Twelve month ago as parameter in SSRS - reporting-services

I have two main parameters in a Report:
First is to be used to set the month (e.g. Dez 2017), from this Parameter the Report shall set its fromParameter itself (e.g. Dez 2016 in this case).
What is the easiest way to solve this issue? Is there a dateadd formula, calculating backwards from a Parameter?
My first Parameter is set by a formula like this(creating the last month):
('[Date].[Fiscal].[Month].&['+Format(DateAdd("d",-39,now()),'MMM yyyy')+ '] ')
Or do I have to calculate the "fromperiod" first in a query? How could this look like?
In the end the reporst should still be flexible, so changing its 12 month period based on would the user is selecting in the end.

Try this expression for the start date parameter default value to set it 1 year before the the parameter end date.
=DateAdd(DateInterval.Year, -1, Parameters!EndDate.Value)
Or you could do the reverse if you wanted to base it off the parameter start date.

SSRS select parameter month and change par. first and last day of this month

i need to create parameter list of months and then (after select) recalculate two others paramateres in date format ([first day] and [last day]) of this month, can you please help me?
You are querying a database server to generate the list of months, although there's no need to do that. I suggest to rather create a list of months in the report and let the report calculate the month's names, so the language depends on the Language setting of the report (which can be the language configured in the user's browser).
For example, to calculate the Label for the Value 1, use an expression like =MonthName(1).
The Parameters FirstDay and LastDay (or just the values whenever you need them) can be calculated using these expressions:
FirstDay: =DateSerial(Today.Year, Parameters!Month.Value, 1)
LastDay: =DateSerial(Today.Year, Parameters!Month.Value, 1).AddMonths(1).AddDays(-1)

SSRS Dynamic Date Parameters

I'm fairly new to reporting and need help with the following?
I have a report that has two date parameters statically set to default to the last financial year. i.e. the FROM parameter 01/04/2015 and the TO parameter 31/03/2016.
When the actual date next year is 01/04/2017 I need these parameters to change forward by one year, I know I maybe able to do it with a case statement and a getdate + dateadd .
I have a small table which creates a year period based on certain dates which I then join onto the data then I use that to filter.
for instance:
1516
1617
1718
so if #year_period = 1516 then the previous year would simply be #year_period-101 and the future would be #year_period+101

Comparing todays date against first day of the week

I am trying to set a default parameter value in SSRS report. I want to test the current date to see if it equals the first day of the week (in my case Monday). If it is the first day of week, then I want the default value to be current date minus 2 days, if it is not the first day of the week then I want the default value to be current date minus 1 day.
I seem to have a syntax problem but it doesn't tell me where. My parameters are StartDate and EndDate.
this is what I've tried:
=iif(weekday(Today(),FirstDayOfWeek.Monday)==1,DateAdd("d",-2,today(),DateAdd("d",-1,today())
this is the generic error I get:
The value expression for the report parameter 'StartDate' contains eror:[BC30201] Expression expected.
Where am I going wrong?
You are trying to use Sql syntax in a SSRS VBA expression. SSRS VBA allows very similar expressions for date manipulation to Sql, the main difference being the use of the DateInterval enum.
So your expression needs to use VBA syntax:
=IIF(Weekday(Today, FirstDayOfWeek.Monday) = 1, DateAdd(DateInterval.Day, -2, Today), DateAdd(DateInterval.Day, , -1, Today))
It appears that you are missing a closing parentheses after the first logical part of the if statement and another to close the statement.
=iif(weekday(Today(),FirstDayOfWeek.Monday)==1,DateAdd("d",-2,today()),DateAdd("d",-1,today()))

SSRS - weekday name

any advice appreciated
I have as a column heading the expression =WeekdayName(weekday(fields!date.value))
This returns the day of the week, however, it is returning a day of the week one day in advance, eg when I put Monday's dates in the parameter it shows as 'Tuesday' in the report.
My question is can the above expression be tweaked to show the WeekdayName one day before, eg =WeekdayName(weekday(fields!date.value -1)) ? I tried this but got an error.
Thanks.
So you want to subtract one day from the your incoming date then you can use the
= DateAdd("d", -1, yourdateField)
This way you can subtract the any number of days from your date.
But did you try to see why it is giving the day of previous date. Do check the system date time or else check with the
=WeekdayName(weekday(Today()))
and see if it gives you the correct day of week for current date.
Weekday and weekdayname functions have both another optional argument for defining the starting day of the week.
Problem is the 2 functions don' t default this argument to the same value so depending on your server settings you should explicitly set the second argument of these functions.
No need to invoke a date function. As the weekday() function returns and integer you can offset the result and use the Mod operator to keep it in bounds:
=WeekdayName((weekday(fields!date.value)+5) Mod 7)+1)
The parenthesis are important to ensure the addition comes first.
Just for reference:
OP asked again because of the weekday offset and this is the correct provided solution.
=WeekdayName(weekday(Today())) gives me tomorrow
=WeekdayName(Weekday(Today(),FirstDayOfWeek.System))

How to get current month name in SSRS?

I need current month name as default perameter name in my ssrs report. How can I get current month name using an ssrs expression?
For example "27-09-2012" would become "September"
and one more i need....
27-09-2012 to previous month name as well (August)
First question:
=MonthName(Month(Fields!datefield.Value))
Second question:
=MonthName(Month(DateAdd("m", -1, Today())))
I think the second question answer might be something like that, first converting the date to month then subtracting 1 from the month value and then converting it to month name.
Further reading:
SSRS Reports get Month name from Month Index or from date
Converting month number to month name in reporting services
OFF: I would change the date format you are using to 2012-09-27 as it works in every setting and should give you peace of mind when converting date formats.
Don't subtract 1 b/c it won't work for January.
Use this:
MonthName(Month(DateAdd("m", -1, CDate(Today))))
As a note, I tried the suggestion of =MonthName(Month(today())). What I would get is #error for whatever field the expression was in. However, =MonthName(str(Month(today()))) worked for me. I am unsure of whether or not the MonthName method changed to require a string or if it is some issue with my program. Just figured I would post this in case anyone else was having the same issue.
For Previous Month i found universal way : =MonthName(Month(CDate(Today()))-1,False) for SEPTEMBER (Full Month Name) 'OR'
=MonthName(Month(CDate(Today()))-1,True) for SEP (Short Month Name)
