I have to update REGIOGROUP field in the ADRC SAP standard table.So I created FM for this purpose and did call it before the save event( i.e Collecting data to internal tables event).In this FM I got the REGIOGROUP value and updated this value in the IADRC internal table of function group SZA0.Because this table is used at the time of save.Before updating ADRC table IADRC values are moved to *IADRC.Here my problem is I can't see the REGIOGROUP value in *IADRC but I can see this value in IADRC.Please help me to solve this problem.Thanks in advance.
Please have a look at the code
save data back to memory
assign ('(SAPLSZA0)IADRC') to <adrc>.
assign ('(SAPLBUA0)IADRC') to <row>.
loop at lt_adrc.
read table <adrc> assigning <row> index sy-tabix.
move-corresponding lt_adrc to <row>.
