Hi Veselina,
Thank you for your prompt reply,
Yah Right , we cannot use same cancelled billing type(ZS15) to same cancelled billing types( ZS15) and tried that option before posting the issue in SCN in test system but I thought that is not good practice.
Due to that reason , I posted this issue in SAP SCN but if go for new billing document type creation ,also copy control need to do and little bit extra activities need to perform
But I will do R and D , will update the status accordingly
But small clarification, shall we use same cancelled billing type number series to new billing type?
Best Regards
