Custom fields on MIGO screen not updated to MSEG

Hi folks,

I have built a new custom tab in MIGO using the BADI 'MB_MIGO_BADI'. Its working fine and the custom fields are able to save the data to ztable but couldn't able to save those data to MSEG even though i have appended those custom fields in MSEG.

POST_DOCUMENT method in the BADI has the MSEG as import parameter and hence it doesn't allow as to fill the custom data in MSEG over there.

Is there any other specific way to fill custom data on MIGO to MSEG table ? Thanks in advance.

Regards,

Shyam.
