Concurrent access with Database repository by RMA and Business application

Thanks for the response. I have tried to answer your questions below.

It has been designed to check if the application is executing the rules and if yes, the RMA is locked for the business users to perform any further edits.

I would want to decouple this activity, like the business users should be able to access RMA anytime they want and the application should continue to work with the version it had when the processing started. The application is a long running process say about half an hour or more, out of which a portion of the logic consumes the rules. So. the RMA users dont want to wait until the application completes its processing.

There is only one rule service invocation from the application

There are no adb files as of now, its a direct DB access.
