MIGO - Save EQUNR and SGTXT in MSEG table

Hi Consultants,

I got a requirement to capture equipment and line item text in MSEG table while posting Goods Issue using MIGO transaction.

screen fields are goitem-equnr and goitem-sgtxt.

I have implemented the below code in EXIT_SAPMM07M_001 by referring the link https://scn.sap.com/thread/1684133 But no luck.

IF E_SGTXT is initial.                                                             

   E_SGTXT = I_MSEG-SGTXT.                                                          

ENDIF. 

Could you please help me in getting the solution for this requirement? If anyone have already implemented and if it is possible, provide me the code.

Thanks in advance.

Regards,

Naushad
