Save GOITEM-EQUNR and GOITEM-SGTXT in MESG while posting MIGO GI

Hi Experts,

I have a requirement to capture equipment and item text in MSEG table while posing Goods Issue using MIGO transaction.

Screen fields are goitem-equnr and goitem-sgtxt.

I have referred the following link and implemented exit EXIT_SAPMM07M_001 but no luck.

IF E_SGTXT is initial.                                                             

   E_SGTXT = I_MSEG-SGTXT.                                                          

ENDIF. 

Could you please help me in getting solution for this?

Thanks in advance,

Regards,

Naushad
