ABAP program to find previous request in cube and delete

There will be cases when we cannot use the SAP built-in settings to delete previous request. The logic to determine previous request may be so customized, a requirement.
In such cases you can write an ABAP program which calculates previous request basing our own defined logic.

Following are the tables used:

RSICCONT ---(list of all requests in any particular cube)
RSSELDONE ----- ( has got Reqnumb, source , target , selection infoobject , selections ..etc)

Following is one example code. Logic is to select request based on selection conditions used in the infopackage:

REPORT ZGET_LAST_REQ_SHORT_RUN.
PARAMETERS: TAR_CUBE(9) TYPE C,
SOUR_ODS(9) TYPE C.
DATA : IT_REQ LIKE TABLE OF RSICCONT.
data : it_REQ_WA type RSICCONT.
DATA : IT_CALMONTH_LOW TYPE /BI0/OICALMONTH.
DATA : IT_CALMONTH_HIGH TYPE /BI0/OICALMONTH.
data : diff type N.
DATA : IT_REQ_CUBE LIKE TABLE OF RSSELDONE.
data : it_REQ_CUBE_WA type RSSELDONE.
data : sour_tar(22) type C.
TABLES : ZBW_PARAM.
CLEAR It_REQ.
CLEAR it_REQ_WA.
CLEAR it_REQ_CUBE.
CLEAR DIFF.
concatenate SOUR_ODS '_TO_' TAR_CUBE INTO SOUR_TAR.
SELECT * FROM RSICCONT INTO TABLE IT_REQ WHERE ICUBE = TAR_CUBE.
LOOP AT IT_REQ INTO IT_REQ_WA.
SELECT * FROM RSSELDONE INTO TABLE IT_REQ_CUBE WHERE RNR = IT_REQ_WA-RNR AND SOURCE = SOUR_ODS AND FIELDNAME = 'CALMONTH'.
ENDLOOP.
LOOP AT IT_req_cube into it_req_cube_wa.
IT_CALMONTH_LOW = IT_REQ_CUBE_wa-LOW.
IT_CALMONTH_HIGH = IT_REQ_CUBE_wa-HIGH.
diff = IT_CALMONTH_HIGH - IT_CALMONTH_LOW.
if diff <= 3.
ZBW_PARAM-ZKEY1 = 'INV_SHORT_REQ'.
ZBW_PARAM-ZKEY2 = SOUR_TAR.
ZBW_PARAM-ZDATA = IT_REQ_CUBE_WA-RNR.
MODIFY ZBW_PARAM.
ENDIF.
endloop.

Once after reqnumb is found out, you can pass
cubename, reqnumb as inputs to FM : RSSM_DELETE_REQUEST and get the job done.
