Hello Vikrant,
It is possible that the STEUC field display the data from field J_1BNBM as we can see in codes of program LMEGUICII:
--------------------
READ TABLE my_dynpro_fields INTO ls_dynpro_entry
WITH KEY fieldname = 'STEUC'.
IF sy-subrc = 0.
ls_dynpro_entry-fieldname = 'J_1BNBM'.
MODIFY my_dynpro_fields FROM ls_dynpro_entry INDEX sy-tabix.
ENDIF.
--------------------
Field J_1BNBM is determined in LMEPOF42. If there is no material code, please check the material goup and check table T023, field J_1BNBM for the material group. If T023-J_1BNBM contains the data, it could be displayed in screen field MEPO1344-STEUC.
Regards,
Diana
