SSRS linked table fields - reporting-services

I am trying to adapt a report we run from our Epicor ERP system. The relevant tables that this report uses are "Part" and "PartMtl". PartMtl relates a parent part to it's child parts, and Part holds the details about a part. So the report is a parts list for a particular part (determined by PartMtl), and then each child part has some details (which it gets from the Part table).
The query doesn't actually contain any JOIN statements, it just pulls the fields from the PartMtl table. I added a JOIN statement to pull the fields I want from Part, but that didn't work. Then I noticed that the query already pulls some fields from the Part table, but not with a JOIN statement. The fields in question start with MtlPartNum, and then have an underscore and the name of the field in the Part table. I tried to add my fields to the query using this format, and then adding them to the list of fields, but this throws an error about a non-existent column in PartMtl.
My question is, what is going on behind the scenes in SSRS that is setting up those underscored fields as being part of the Part table instead of the PartMtl table? When I try to add fields in the same way it just assumes they are part of PartMtl and throws the error.
="SELECT T1.RptLanguageID,T1.Company,T1.EstScrap,T1.EstScrapType,T1.FindNum,T1.MtlPartNum,T1.MtlSeq,T1.OverRideMfgComments,T1.OverRidePurComments,T1.PartNum,T1.QtyPer,T1.UOMCode,T1.ViewAsAsm,T1.Calc_Consecutive,T1.Calc_CurrAltMethod,T1.Calc_CurrRevision,T1.Calc_RequiredQty,T1.Calc_UOM,T1.MtlPartNum_IUM,T1.MtlPartNum_PartDescription,T1.RelatedOperation FROM PartMtl_" + Parameters!TableGuid.Value + " T1"

The reporting system is Epicor ERP 10 uses a report database to hold the data for the reports. When the report is run the data is generated into the reports database using tables with the GUIDs in their names i.e. PartMtl_" + Parameters!TableGuid.Value. These tables reside in a separate database to the main ERP DB.
The field names are probably pulled in as Linked fields in the Report Data Definition. These are managed through a form in the application and the documentation should tell you how to add fields.

Use query's hidden columns/fields in MS Access report

I have a query which joins a few tables. The query asks for a parameter when it is run. Then it displays a few columns/fields from its results, the other fields (like, the entered parameter and other fields that are common to all rows) are hidden. I'm trying to create my first Access report based on this query and I'd like to use some of these hidden fields as a record source for text-boxes/labels but I've been unable to do so. Those fields don't appear in the list of possible record sources.
I've tried the Add Existing Fields button and selecting the field I want from Fields in related tables but when the bound textbox shows up in the report with an error like Invalid Control Property. No Such Field in the Field List which I think means the fields are still invisible to the report. Would appreciate any help getting this done.
The answers is to edit the query and include the missing columns so that they are available to the report.
For non-selected query columns, the use of the word "hidden" is misleading. The way that SQL works--even beyond SQL in the overall concept of datasets--is that only subsets of data are requested in a query. If certain columns are not selected in a query, they are plainly and simply NOT available in the resultant dataset.
It may be possible to re-aquire the excluded columns with another query, but that still does not imply that missing columns were just "hidden". In the case of a subsequent query to get different columns of data, the database engine must re-analyze the new query, re-read the data, then compile the data from the new set of columns to be returned in a completely new subset of data. It is a complete round-trip process that is much more involved than just un-hiding the data.
Forms and reports are completely different types of objects that can mark fields as "hidden", but a query is not the same despite being displayed in a datasheet. Objects like Access Forms and Recordset objects in (VBA) code are designed to hold subsets of queried data, so they are able to temporarily hide (or ignore) or un-hide certain fields without re-querying the database. (Technically an Access Form has its own Recordset object for holding and managing queried data.)
Even though Access is "self contained" with both database and user-interface elements, it is still primarily a standard RDBMS (Relational Database Management System). The principle idea in efficient data handling of an RDBMS is to get only what you need for the current operation. Consider that SQL can be used to query data from a remote server. Even Access can get data from and update data on SQL Server, for example. If data fields were only "hidden" when not included in a query, that would imply that the entire database (or at least an entire table) would be passed back and forth, and that the only thing hindering getting at any column would be "making it visible" as though it is actually immediately available. That would be terribly inefficient both for memory and for remote communications.

SSIS - Reuse Ole DB source when matching Fact against lookup table twice

I am pretty new to SSIS and BI in general, so first of all sorry if this is a newbie question.
I have my source data for the fact table in a csv, so I want to match the ids against the surrogate keys in lookup tables.
The data structure in the csv is like this
... userId, OriginStationId, DestinyStationId,..
What I am trying to accomplish is to match the data against my lookup table. So what I am doing is
Reading Lookup data using OLE DB Source
Reading my csv file
Sorting both inputs by the same field
Doing a left join by Id, in order to get the SK
This way, if there is no match (aka can't find the surrogate key) I can redirect that to a rejected csv and handle it later.
something like this:
(sorry for the spanish!)
I am doing this for each dimension, so I can handle each one with different error codes.
Since OriginStationId and DestinyStationId are two values from the same dimension (they both match against the same lookup table), I wanted to know if there's a way to avoid reading two times the data from the table (I mean, not to use two ole db sources to read twice the data from the same table).
I tried adding a second output to the sort but I am not allowed to. The same goes to adding another output from OLE DB Source.
I see there's an "cache option", is the best way to go ? (Although it would impy creating anyway another OLE DB source.. right?)
The third option I thought of was joining by the two fields, but since there is only one field in the lookup table (the same field) I am getting an error when I try to map both colums from my csv against the same column in my Lookup table
There are columns missing with the sort order 2 to 2
What is the best way to go for this ?
Or I am thinking something incorrectly ?
If something was not clear let me know and I'll update my question
Any time you wish you could have multiple outputs from a component that only allows one, all you have to do is follow that component with the Multicast component, whose sole purpose is to split a Data Flow stream into multiple outputs.

I have just used this article on how to derive columns for a data warehouse building:- How to Populate a Fact Table using SSIS (part 1).
Using this I built a simple package that reads a CSV file with two columns that are used to derive separate values from the same CodeTable. The CodeTable has two fields Id and Description.
The Data Flow has two "Lookup" tasks. The first one joins the attribute Lookup1 against the Description to derive its Id. The second joins the attribute Lookup2 against the Description to derive a different Id.
Here is the Data Flow:-
Note the "Data Conversion" was required to convert the string attributes from the CSV file into "Unicode string [DT_WSTR]" so they could be joined to the nvarchar(50) description attribute in the table.
Here is the Data Conversion:-
Here is the first Lookup (the second one joins "Copy of Lookup2" to the Description):-
Here is the Data Viewer output with the to two derived Ids CodeTableFirstId and CodeTableSecondId:-
Hopefully I understand your problem and this is of use to you.

use two different datasets in single report

I have two different-2 datasets with different fileds which are getting populated through two stored procedures with same input parameters.each datsets have different colums and no of columns around 180,my concern is how will i use these two different datsets in single report with two differents fields(two differnt tables).for one dataset i have used report wizard,but not able to figure out for the second dataset.Please suggest for the same..
You can use two different datasets in different reports regions on one Report. For example, If you have two datasets, lets say DS1 showing EmployeeDetail and DS2 showing SalesInfo. You can use them separately in two tables one showing Employees Details and other showing Sales Info. If you plan to merge this data and use it in one table, These are option.
Recommended option : Re-write your query to create single dataset containing possible data you want to show in tabular fashion.
Would work but would be lot slower : Use DS1 in a table in Main Report where each row contains Epmloyee Detail, Wihtin that Row call a Sub-Report passing EmployeeDetail's key which is related to a column in SalesInfo. Create sub-report showing SaledInfo data, call this report in main report passing key value from DS1 to this sub-report.
Specify data set name in third column
Example:
=First(Fields!fieldname.Value,"DataSet1")
Using two different or multiple datasets in a report is not a problem at all, as long as they do not belong to the same data region (charts, tables, etc.)
In addition to Ron's answer, if you are looking to get data from different datasets in one data region, you could also use Lookup or LookupSet in the field expressions.
Additionally, you may also create one dataset and filter out some data from it in data regions. For example, if you have one big dataset of all employees, and you would like to display all employees that joined in the year 2012 in a table, you could filter out the dataset using Filter properties of table.
You can simply add multiple table in your report , and change datasetName from tablix properties for each of your table .
you will also need binding source to fill that dataset .
this.invoiceTableAdapter.Fill(this.ARQutationDataSet.invoice);

Microsoft Dynamics Data Import Failing with Unresolved Lookup

I'm attempting to import a csv file in Microsoft Dynamics 2011. The file is an export of sales data from our website and I'm attempting to create new Account, Contact, Invoice, Order, Invoice Product and Order Product entities using this data. I'm using a multi-entity data map to do this.
When I attempt the import however, creating the invoice fails with the message "The lookup reference could not be resolved." in connection with the currency field. This field is a lookup tied to currency name which in all cases is "US Dollar". This is exactly the same name as the USD currency in our database, but for some reason the lookup refuses to assign it correctly. There are no other currencies in our database with this name.
Can anyone offer me an explanation as to why this is happening and any steps I can take to deal with it? Many thanks.
EDIT: More information about my problem.
It seems that problems occur when I try and perform a multiple entity import with duplicates. All the new entries I'm creating from this import is dependent on other new entries created with the same data. I'm creating accounts, then creating customers to assign to those accounts for example. If said accounts have duplicates already in the system, they are ignored. This is expected. However, when it comes to create the customer assigned to that account, the lookup fails with a "Duplicate lookup reference was found" error. This error occurs when there are more than one things in the database that fit the value I'm using with the lookup.
I'm not 100% sure, but I think it's counting both the account that was ignored and the original account that's already in the system when performing the lookup. Can anyone offer more insight on how I might work around this?
I don't know for sure if this is your issue but my guess it is.
In the import wizard you can select how he resolves your lookups.
i.e: when in your CSV file the column contains the name of the currency you will have to select the name field in your import wizard for the currency field.
In the screen here you can see then country is a lookup and the name of the country is the value of CSV file. It must match the field of the lookup. If I select "created on" It doesnt find the lookup. because no country exists where created on equals "Belgium". So you select the Name field of the lookup and that is how he will check your value in the CSV in the lookup field you defined.
1.Put records for each record type in a separate file.
2.Put records for different owners in a separate file.
3.Ensure that the first line of the file contains column headers and that they match the CRM attribute display names EXACTLY if you would like the import wizard to automatically* map the data. *Automatic mapping is required if you intend to import records that are related to another record (See #6). I HIGHLY RECOMMEND USING AUTOMATIC MAPPING EVEN IF YOU DO NOT DESIRE RELATED RECORDS.
4.Make sure the first column heading is not the name of a record type.
5.Make sure data exists in your source file for all CRM required fields (denoted with a red asterisk on the CRM form).
6.Make sure some data exists for each column. If a column has no data delete the column.
7.If your data should be related to another record (i.e. Adding Contacts to existing Accounts) make sure the column header matched the CRM lookup attribute display name. If you have two different attributes in CRM with the same display name you will receive an error (EX. if you created a custom State picklist value to replace the text version and keep the display name the same "Address 1: State/Province"). Also make sure the company name values will match a corresponding account record (i.e. contacts with a Parent Customer value of Microsoft Corp. will not be added to the CRM Account Microsoft) and that there are no duplicate Accounts in the system as the import will not be able to resolve the proper Parent Customer.
8.If you are importing into a drop-down list, ensure all the values exist within CRM and there are no typographic errors and consistent capitalization in the source file.
EDIT: It seems like indeed there are multiple records in your DB that can fit in that 1 lookup. it's normal that he gives an error on this as he can't resolve the lookup. The CRM doesn't know which record to take.
Also you might want to watch out if you are importing a M-N Relationship. You will have to do a M-N Relationship with code. The standard import wizard cannot handle Many-to-many relationships

MS Access Report showing the id of the combobox and not the bound name column

The company I work for have an access database that is linked to a sql server table. The database is on a shared network location so it is used by lots of people in the company (with the annoying problem that only one person can use it at a time).
There are several forms that are used as a front end for the data and on one particular form there are combo boxes that are linked to other tables.
When a report is generated on the form the ID of the combobox is on the form (a GUID) and not the bound item of the combobox.
How can I get the bound items to appear on the form itself? The solution needs to be easy to do or something i can produce that can be regenerated as it's used by non technical people.
In order to make the database usable by many, simply give each user a copy of the front-end.
Forms should almost never be used for reports, the best thing to do is to build a query (the query design window will help) that references each of the relevant tables, for example, if the combobox contained a reference to person type and you might build a query like this for your report:
SELECT a.ID, a.SName, a.MainAddress, c.PersonType
FROM Addresses a
INNER JOIN PersonTypes c ''Or LEFT JOIN if data is missing
ON a.PersonTypeKey = c.PersonTypeKey
If this is not possible, perhaps you could explain in more detail exactly how the report is generated from the form.
