I am enhancing a zfield in extract structure for 2lis_13_vditm. I have added the zfield in the append struture & activated it.
Zfield is populated from the table VBAP. I wanted to write an User Exit (EXIT_SAPLRSAP_001) to populate this zfield at CMOD.
As I am not well versed in ABAP,I would really appreciate if you can help me to write a code to populate this zfield from VBAP.
