MIGO field selection - vendor batch number

Question

I created a new movement type by copying from the standard SAP movement type 501 (GR w/o purchase order).
When posting a GR with this movement type and a batch-managed material, the Batch field is open for entry but the Vendor Batch field (GOITEM-LICHA) is suppressed. I suppose this is because SAP does not expect you to enter any vendor-related information if you do not have a PO. And similarly if you have vendor-related information (like a vendor's batch number) you should be using a PO.
However the business requires a Vendor Batch number to be entered in this scenario.
Does anyone know how to make the Vendor Batch field open for input when using a specific movement type?
I'm thinking maybe a BADI like MB_MIGO_ITEM_BADI is my only option. I've tried the MIGO field selection (OMJX) but couldn't make this work. Any input would be appreciated.
Thanks!

Answer 1

I am afraid I must confirm that, as you have already seen, it is not possible to enter a Vendor Batch (LICHA) in a goods receipt without reference to the purchase order with the movemement types 501, 511 or 561.
There is no standard system setting or program code available which can set this entry as required or optional. This kind of requirement can only be achieved through a software modification,
Also, please notice that although you can enter a Vendor Batch when posting a goods movement with reference to a purchase order, you cannot display it later with transaction MIGO:
Please, kindly check the information contained under the attached note regarding this matter:
330585 - MIGO: Vendor batch in material document display.
As stated in this note, under the 'System response after the note is implemented' section:
"After the attached correction instructions are implemented, the field
  can no longer be seen in the display of the material document for the
  vendor batch using Transaction MIGO. Displaying the vendor batch does
  not make much sense since it might have changed since the posting of
  the material document. The material document itself does not have the
  information of the vendor batch that was entered at that time. In the
  system, only the information of the current vendor batch exists for
  the batch."
Sorry not having a positive answer ! =/
