BADI/Userexit needed for creation of invoice reference to automatic invoice created during PGI using the transaction code VL02N

Hi All,

I have a requirement to create the invoice reference to automatic invoice created during PGI using the transaction code VL02N.

Please help me to provide the BADI/userexit to get the automatic invoice created during the PGI so that i can put the code for creation of invoice reference to automatic invoice created in background as per outbound delivery entered in VL02N.

I had put the code in BADI's method : BADI: LE_SHP_DELIVERY_PROC even in BADI: LE_SHP_GOODSMOVEMENT but not getting the invoice number reference to VBFA-VBELV and VBFA-VBELN . Means no entry created in BKPF.

I have also put the code in user exit: MV50AFZ1 but same issue no entry generated in BKPF reference to delivery number entered in VL02N and click on PGI.

Please suggest .

Thanks in Advance.

Regards,

Jatin
