physical documents list for upload

Hello Experts,

Greetings for the Day!!!

We are about to implement DMS at one of our client location. Though the question may sound too basic, client wants to know how other companies utilize DMS from the physical (NON-SAP) documents point of view. for eg.,

1. for PO, we can attach RFQs,Terms & conditions(MoUs) etc..,

2. for equipments in PM, their mfg manuals & related docs.

3. for projects/WBS in PS, the drawings,consultancy docs etc..

kindly help me in differentiating different documents per business transaction for PO,MIGO,MIRO,sales order,delivery&invoice.

Best Regards.
