Under certain circumstances it is possible to have two different documents with the same document number in Microsoft Dynamics GP.

For example, after creating an SOP document but before posting it, a document can be created and posted in receivables transaction entry with the same document number. When this happens, Microsoft Dynamics GP will append a sequential number to the end of the SOP document number during the posting process.

The “Modifed Document Number” will then appear in document inquiry and various reports including the DynamicZip Tax Reports. However, the document number is not modifed in SOP transaction history.
