I'm putting together an SSRS report in BIDS 2008. I've got a parameter - we'll call it ParamA - that's set to allow multiple values, and, in Available Values, I've set it to 'Get values from a query'. When I run the report, I get the following error:
An error occurred during local report processing.
The definition of the report '/Report2' is invalid.
The report parameter 'ParamA' has a DefaultValue or a ValidValue that depends on the report parameter "ParamA". Forward dependencies are not valid.
When other people get this error, it seems to involve multiple datasets, and the forward dependencies always deal with two different parameters. I'm using only one dataset, and only one parameter is cited in the error.
Any advice would be great.
Have you checked the order of your parameters in the report designer toolbar. If they are ordered incorrectly the report will fail because of the order required to make the dependencies work. You use the little blue up and down arrows to set the order of report parameters
I think I figured out the problem. Using a multi-value parameters requires that each such parameter have its own dataset. I only had one dataset, and I was trying to point the MVP at it and run the report off of the same set. I don't know why that doesn't work, but I added a dataset for the MVP, and the error went away.

First I would like to apologise for any mistake and misuse of the english language as it is not my natural language.
I built a few reports using SSRS. Each one are feeded through different stored procedures.
Each stored procedures has two parameters: id and date. When I display the report the parameter I only want to be visible the date that will be supplied by the user. The id should be hidden and with the default value of 1. So, I turned the parameter id to hidden and set up a default value with the value 1. Im setting the default value on a report's definition level instead on the datasets used to feed the reports. PLease see below the steps I have done:

I've been through some websites(stackoverflow included) and I've seen similar issues. I followed the suggested tips but still no success.
Any help on this will be very appreciated.
Thanks
P.S. Im using VS2015 to design the reports and SQl Server 2014.
Without knowing more, my first instinct suggests that you have your parameters ordered incorrectly. If you have a parameter, P2, with a default value that is processed after a parameter without a default value, P1, and both parameters are hidden, then the report will fail citing that P1 is missing a value.
See my screenshot below as an example. You need to make sure that the parameters are loaded in the order, vertically, that they should be processed, especially if one parameter is dependent on another. Take a look at the ordering and leave a comment if you need further information.

Try opening the report manager via the Report Server web interface (http://[serverName]/[instanceName - reports is default]/Pages/Folder.aspx?ItemPath=/[directoryOfReport]). Click on the dropdown list beside the report name and choose manage. Check out the parameters tab and make sure the default is set properly. Sometimes, if you've messed with parameter properties numerous times in BIDS or report builder, the settings won't translate onto the server itself. Let me know if that fixes it.
I am receiving the following error from my child report: "The report parameter 'prmDefaultValueForSnapShots' has a value of DefaultValue or a ValidValue that depends on the report parameter 'prmStoreName'. Forward dependencies are not valid."
I have a parent report that feed values to the child report to display all sales data for the specific store. However, this report is rather large, thus I'm trying to set a snapshot for it on the Report Manager to execute in the early mornings for better user experience. For the snapshot to work, I need a default value on the parameter and I have been unable to make it work.
If anyone has any idea how to resolve this particular issue. Please, give me any suggestion as you can.

I have been researching this issue since Tuesday and I have not had any luck.
I'm not entirely sure I understand your goal or configuration. I'm also not sure if prmDefaultValueForSnapShots and prmStoreName are parameters of the main report or the sub-reports, and which of the two throws the error.
However, this error may occur if a parameter depends on another parameter which is not yet provided. Note that the order of the parameters is important. By "order", I mean the order in which they are defined, which is also the order in which they appear in the list (you can reorder them using the arrow buttons).
Is it possible that prmDefaultValueForSnapShots depends on prmStoreName, but is defined before it?
Issue I get for one of my shared data sets only on certain parameters. If the parameter returns nothing for that dataset then I seem to come across this problem, there is a tablix in this report that uses the shared dataset and if I remove the tablix but keep the shared dataset I still get the error on the report preview.
The dataset uses a MDX query (SSAS) to get its data, if I run the query from the query designer it returns 2 rows but the dates in the rows are outwith the scope of my report so the report would return 0 and I assume thats my issue.
Anyone got any ideas/tips?
Uses SQL Server 2008 R2
Thanks
Managed to get round this issue by having an embedded data set rather than a shared one.
Gets around the issue, very annoying though!
I am using SSRS 2005. I have one parameterised report. I am using 3,4 cascading parameters. my last parameter can have upto 5000 values in it. I want to know that what is the maximum limit of multi-value parameter becuase when i select deselect some parameters I got one error "Operation is not valid due to the current state of the object." I wonder if it is due to lot of values in one of the parameter.
Please guide.
Thanks
I can't find a source for a hard limit of number of parameters but to be honest if you're using 100s I think you're going to run into usability issues first.
I'd suggest grouping the options by one or two more cascading parameters that narrow down the range if that's possible for your application.
From here
There is a constraint (on .NET framework or Web server I think) that allows only 1,000 values to be loaded under parameter drop down boxes
I have what I thought was a very basic SSRS scenario. I have two datasets in my SSRS 2008 report; dsMTD and dsYTD. They both contain the same columns, the only difference is the SQL statement that fills them both (but I don't imagine that's really relevant to the problem).
I have a textbox on my report, and I wanted to show the SUM of a certain column within the report. I tried to make my expression as follows:
=Sum(Fields!cost.Value, "dsMTD").ToString()
This works fine in SSRS 2005, but the expression in SSRS2008 gives an error of "Unknown Collection Member" on the field reference in my expression.
Am I not doing something right? I've recently installed CU6 for SQL Server 2008 on my machine, and wonder if that has changed something?
Just ignore this. The error is just misleading I assume. At first I was running and my dataset actually had no rows, which explained why a value wasn't coming back. I intially thought this was connected to the "Unknown Collection Member" error, but when trying to a different dataset that does have data, I still get that error, but also get the correct value.
I'll try and ask for help on things that actually are wrong next time!
