problem with end date using a LET variable

[Anonymous]

Hi Guys,

I have the following variable:

LET vPeriod      =            date(Makedate(YEAR,Month,1),'YYYYMM');

When I use one of these expression in my field date(Makedate(YEAR,Month,1),'YYYYMM') as Period, it works

Now I want to create the end period using the Let statement 'vPeriod'

Load

year,

month,

Date(monthstart(addmonths('$(vPeriod)',12)),'YYYYMM') as EndPeriode

From Database......

I don't get any error when reloading. However no data can be found in the EndPeriode.

What am I doing wrong?

Hi,

     Did you checked without $()?like this

Load

year,

month,

Date(monthstart(addmonths(vPeriod,12)),'YYYYMM') as EndPeriode

From Database......

Hi iSam,

Just do not warp the expansion using single quotes:

Date(monthstart(addmonths($(vPeriod),12)),'YYYYMM') as EndPeriode

Hope that helps.

Hi Miguel,

If i do that, I get the following error:

Error in expression:

')' expected

My expression seems to be oke right?

      date(monthstart(addmonths($(vPeriod),12)),'YYYYMM') as EndPeriod

Thanks for you help!

Hi,

If I remove the $ sign I get the error that the field cannot be found. Which makes sense

Thanks for your help so far.

Hi Aboumejjane,

Maybe this solution is not so smart, but I think it works:

LET vEndPeriod = Date(monthstart(addmonths(vPeriod,12)),'YYYYMM');

LOAD data,

     Year,

     Month,

     if (1=1,$(vEndPeriod)) as EndPeriode

FROM ...

I hope it helps

Hi Isam,

You are using Date() function with a value that is not a date (the variable). According to your LET script above, the following works here, note the Date#() function:

Date(MonthStart(AddMonths(Date#($(vPeriod), 'YYYYMM'), 12)), 'YYYYMM')

Hope that helps.

Hi Miguel,

Thanks for your help and sorry for my very late response!

I found the problem. I was using the date function twice, once in the in the variable and once in my expression.

It should have been     Let vPeriod =  Makedate(Year,Month,1);

Load

*,

Date(monthstart(addmonths('$(vPeriod)',12)),'YYYYMM') as EndPeriod

I haven't tried your solution yet, But I assume that that will work also.

Many thanks for your help!!!
