If can use business rule to do the data alignment?

Background: 

I usually handle some similar case, someone consumed the Service Offerings data and created some report/dashboard, due to some reason, there are some data discrepancy from parent business application to map application service to service offerings after/during migration/transformation. 

In above of scenarios, I have to create the fix script which it will based service offering data to compare with parent appsvc/busapp, and perform the subfix if any data discrepancy.

Fix script just for one fix, normally there are some business rule to control the data from busapp to appsvc to SO, but I'm wondering if can use business rule to control the legacy so data issue instead of use fix script again & again? Or if any other idea to improve it?
