help required in F4IF_INT_TABLE_VALUE_REQUEST

hi all,

I am using F4IF_INT_TABLE_VALUE_REQUEST function for F4 list , below is the code im using,

MOVE it_ret-fieldval TO zmatnr.

ENDLOOP.

ENDIF.

My requirement is , In my selection screen i have field ZMATNR , with the above coding i can get the selected MATNR into that, but in addition to the selected matnr i need to get the corresponding WERKS also, which needs to be passed to another variable for further usage, I tried various methods of using "dynpfld_mapping " field tab etc, but nowhere im getting the WERKS value, i dont know whether im doing it correctly. so kindly suggest me to achieve the requirement.

thanks and regs,

Raja
