I looked for a detailed document about ME51N-ME52N-ME53N add custom field in SCN but i have not found fully described. That's why i decided create this blog.



























Symptom :





























Some customers need to add custom fields for their purchasing request documents then try to copy this field other subsequent purchasing documents such a purchase order. You can benefit from this blog for these requirements.

Related OSS Notes : 


1- Add ZZUSER to CI_EBANDB .



2- Create subscreen and fill out modules.

RESULTS :

Purchase Requisition 



EBAN is updated correctly !



I hope that you will need to copy custom fields to subsequent documents such a purchase order. You have to add same field to subsequent purchasing document and fill out fields in subscreen referance to purchase requisition.

If you want to copy PR custom field to PO custom field with a referance, you can benefit from PBO of customer screen in SAPMM06E 0111 CUSTSCR1 SAPLXM06 0111 ! (Screen exit PO)

Enhancement IMP --> MM06E005 Customer fields in purchasing document .

Read custom field PR .
 IF i_aktyp EQ 'H' OR i_aktyp EQ 'V'
SELECT SINGLE zzuser
FROM EBAN
INTO @DATA(wa_eban)
WHERE ebeln = ekpo-ebeln
AND ebelp = ekpo-ebelp.

IF sy-subrc IS INITIAL.
gs_ci_ekpo-zzuser = wa_eban-zzuser.
ENDIF.
ENDIF.

Thanks for your time !
