Hi. Sridhar.
Did your job finish? FDM_COLL_SEND01 reads/update/delete/insert table FDM_COLL_TROBJ while sending AR to collection management and other transactions also insert into table FDM_COLL_TROBJ while clearing AR(objtyp BSEG) or changing Customer master(objtyp KNB1).
If you have huge data in FDM_COLL_SEND01, running program itself needs so long time.
