I'm relatively new to MS Access and creating a Document Register to maintain unique identifiers for documents based on Project and Document Information.
My Table is as follows:
Project : Document Type : Sequence Number
ABC Email 1
ABC Memo 1
DEF Email 1
ABC Email 2
I want the Sequence Number to Autogenerate/AutoCalculate. It should only increment when there are previous records and the record would otherwise be a duplicate. It needs to be stored as part of the field because it cannot change once provided.
Please help!
