I have a document library, where I have few properties to add, like name, title, type, project number etc.
For Example if the project Numbers are ABC, DEF, GHI etc.
As of now the unique document ID appears as below:
ABC/01 where ABC is project Name and 01 is the unique ID which sharepoint generates.
Now, when I add a second document related to a different project DEF. The ID becomes DEF/02.
Is it possible to generate a number DEF/01? If not using ID column, is there any other tools which will enable me to auto number the items based on the column value.
