MIGO : looking for user exit or BADI for batch number

Hello,

I am looking for a solution using an user exit / BADI (or something else ?) for MIGO.

Here is my problem :

When using MIGO (movement code 101) with purchase order reference, I would like to use the vendor batch number (which is in my purchase order : EKET-LICHA) and copy it in the MIGO transaction field (GOITEM-CHARG).

The point is that the "MB_MIGO_ITEM_BAdI" BADI but it only lets me to update the plant and the text post of the MIGO...

I only would like to update the batch number.

Example :

I have one purchase order with "BATCH01" as vendor batch number.

When doing my MIGO, I call this purchase order and some fields are copied from the purchase order. At this moment, I would like to copy "BATCH01" that comes from my purchase order to the field Batch in my MIGO (GOITEM-CHARG)

Any solutions ?

Thanks for your help.

Regards.
