BOM integrity in SAP with respect to part version, engineering changes-DMS

Hai folks,

We have a concept of engg bom and plant bom, when a part no. is intiated for the change management

it goes through a version change which is handled through DMS in SAP.

The scenario is, i want to sink the version of the part with my document version .(i.e in our plant our component part number and drawing document number are same.)

When i do a bom comparison using CS14, different field comparison's are thrown, except for the version difference.

I doubt , since DMS is a centrally controlled area, it makes no sense to compare versions in the same SAP boundary, but can it be managed through some DMS object links in our system.

Pl throw some concepts to ensure different BOM intergrity with respect to part versions and engineering changes.
