Delete data from commission headers/lines

Hi

We have just gone live with our new OIC system and we are running into data collection issues where some of the logic that was applied before pushing the data into OIC was having some issue and now the business needs to go in and manually correct the data.

Is there a way where the transaction data be deleted from the commission_headers and commission_lines and also API and once we run a full calc the attainments for the reps who were getting credit from these transaction should be reset?

Will this work. any suggestion?? to see if we can get a data fix script for this?
