Set analysis with Dates

[parpatra]

Hi,

I have a requirement whhere I need to check how many IDs have their DATE_A in the same range as my  reporting Date.

I am trying a expression in a bar chart where:

Dimension=MONTH

Expression= =COUNT( {<DATE_A={"<=$(MAN_DATE)"},DATE_A={">=$(MIN_DATE)"},YEAR={"2011"}>} ID)

But this expression is not grouping things by Month, as it would be in a bar chart. My MIN DATE AND MAX DATE are calculated columns in t my calender  table.

MIN_DATE= ADDMONTHs(REPORTDATE,-3)

MAX_DATE=REPORTDATE

Any help is appreciated.

Thanks

Hello parpatra,

two things to mention:

your var MIN_DATE includes an expression (Addmonth ...). Due to this you have to use (in addition to $()) the $(=) - operator within your chartexpression. This would then look like:

COUNT( {< DATE_A={"<=$(REPORTDATE)"},DATE_A={ ">=$(=$(MIN_DATE))"},YEAR={"2011"}>} Val)

Second Note:

My var MIN_DATE looks like:

ADDMONTHs( $(REPORTDATE),-3)

and

REPORTDATE includes a valid (german) date:

'28.10.2011'
