Hi,
Try using the UPPERCASE as it is in BPC
call function 'ZBPC_GETDIM_MASTER'
EXPORTING
DIM_NAME = 'ACCT_PL'
APPSET_ID = 'CATHAY'
H_NAME = 'PARENTH1'
ATTR_NAME = 'QTY'
TABLES
E_LT_RESULT = ltt_result.
I wish the values that you have hard coded either doesn't match with BPC ( due to case problem or mis-spell ).
Check this out as its something very minor.
