Dear All,
I have found the reason.
source_rel_ind gets X when itme quantity is greater than quan_po_e
this happens due to the Report "BBP_GET_STATUS_2".
See line 863
IF ls_hlp_refdata-quantity > et_sc_refupdate-quan_po_e
Hereby I am facinf a new problem. Why and Where is the field "quan_po_e"
populated in the SC????
