In SAP 2007 PL 13,after Removing record by right click remove ,I am not able to add the document. It gives error "Document no already exist". After diagnosis Of ONNM and NNM1 table ,I got that next no does not increases in NNM1and ONNM Table.
but this problem came after upgrading from 2005 to 2007.
it happens for some times.
I could not find any reason because I had generated Document no by sap object.
Is it any patch required,I had already run PL 09,10,13
please help me
thanks in advance.
