pro forma invoice attachment

Hi experts,

we are generating proforma invoice for shipment when loading date is set. we are triggering a print output. I could find a badi class CL_SD_BIL_IMPL01 that prints the adobe form. I have to capture this PDF after printing. I couldnt find any badi/userexit after this badi. This method is called in UPDATE TASK by FM RV_MESSAGE_UPDATE.

System is S4CORE on premise.

Thanks and Regards,

Aditya
