How can I delete all loads for a specific infopackage in a process chain?

Question

Good day all,
I've got a BW 3.5 system. and I have a cube which is loaded by two infopackages, I will call them "Current" and "History" which load each month.  On an ongoing basis I only want one "Current" infopackage load and many "History" infopackage loads.  At the beginning of a month before I load a new "Current", I would like to delete any loads in my cube that were loaded by "Current".  It's not an overlapping selection request, so the automated delete won't work - so I'm open for suggestions.
Thanks,   Ken

In the InfoPackage settings - Data Target tab, use the Automatic loading of similar/identical requests option.
Instead of deleting "overlapping", you can request selection through the routine using the following tables:
rsreqdone contains the request numbers and the InfoPackage technical name.
rsseldone contains request numbers and their selection criteria.
Use something like this:
TABLES: rsreqdone, rsseldone.
DATA:   itab_rsseldone TYPE rsseldone,
        itab_rsreqdone TYPE SORTED TABLE OF rsreqdone WITH NON-UNIQUE
        KEY rnr WITH HEADER LINE,
        v_date TYPE sy-datum.
*selecting all requests from RSREQDONE that were loading from this infopackage
select rnr from RSREQDONE into table itab_rsreqdone
where LOGDPID = 'Current Infopackage Technical Name'.
loop at itab_rsreqdone.
*selecting all these requests + selection criteria from RSSELDONE
select single * from rsseldone into itab_RSSELDONE
where rnr = itab_rsreqdone-rnr.
if sy-subrc EQ 0.
v_date = sy-datum.
*if the Month Selection criteria is less than the current system month
*then delete request from target.
if itab_RSSELDONE-low(6) < v_date(6).
*all requests remaining in l_t_request_to_delete are deleted from the data target
l_t_request_to_delete-rnr = itab_rsreqdone-rnr.
append l_t_request_to_delete.
ENDIF.
ENDIF.
endloop.
*do not delete the actual request
DELETE l_t_request_to_delete WHERE
rnr = l_request.
clear p_subrc.
