Delete reduntant PSA data

Question

Hi All,
For an Absence Quota Infocube, we are using pseudodelta mechanism. For automizing this process, we have built process chain. We have used the process type -Delete Overlapping requests, to delete reduntant data in the infocube.
This is a Time Management infocube, it fetches huge amount of data every week. So the PSA also gets bulky over a period of time. The PSA size should be controlled and this should be automatic.
Also, this datamodel has a ABAP routine at Infopackage level. The code logic fetches data of last year and the current month's data if the Calendarmonth of dataextraction is JAN, for all other months it fetches data of current and previous month data.
Due, to the above routine. We cannot use the process type -Delete PSA Request. If we use it, then the infoprovider will have only few months data.
Can you please suggest me a way to delete the PSA contents automatically and at the sametime should not loose any data
Regards,
Vasavi

1. If you are doing this in BI 7.0, write a routine at infopackage level.
Take 0REQUID and 0calday as two parameters. Put a check on request ID which is loaded on which date.
Suppose request ID 12345 is loaded on jan 30th and req ID 67890 is loaded on 3rd Feb.
Now as per your scenario, it should take data for current & previous month only. SO this code will chk for req ID along with the date. If date is greater than 2 (here if calday format is yyyymm, the it considers month older than two months)., it'll delete it.
Here it'll chk req iD 12345 and date as 201001, which is older than 2 months, it'll delete it.
Remember - you can delete data from PSA only request wise and not record by record.
2. If you are doing this in 3.5, then it is much simpler every end of the month, go to PSA , rt click > Deleet PSA Data> teher is an option- OLDER THAN..> put the last date from where you want to keep data till date.
I hope it'll help you.
