An interest document is posted while invoicing but it was not included in open item in DBERDL table. I checked in ERDB table where it shows the document type of this document is clearing document. Ideally document type in ERDB of this document should be "Print with invoice". The main sub of interest document is maintained in the configuration node of "Item selection in invoicing". Then also it does not included in DBERDL. what could be the reason?
