VF02 . Proforma inv printing issue
I have developed a Z smartform for proforma invoice . Now the functional people gave me a output type created for that . Through NACE For billing V3 i assigned my Z form to the output type and in place of driver program i used standard one for invoice that is RLB_INVOICE . Then I went to VF02 GOTO->HEADER->OUTPUT and maintained a row using that output type . After SAVING it got me back to the initial screen of vf02 .And when I am clicking BILLING DOCUMENT-> ISSUE OUTPUT TO an ERROR is coming "DOCUMENT IS CURRENTLY BEING PROCESSED" thus i cant see the prev . And if go to SM12 thr i noticed a lock has thr in table VBRK . After Deleting that lock i can open it again by VF02 . So if u pls help me to sort it out i shall be very thankful .
