is there any correction program is available to rectify the match & approve for BaaN IV C4 Accounts payable .

There are several corrections programs in this area. If they work, is depending on what your specific problem is. Check available programs in tf/cor module.

Around SP8 (not sure) new functionality is available. Check if you have e.g. session tfacp1535m000 on your system. If so, you can post corrections manually and then assign them to the purchase order line where the problem is.

Fixing your reconciliation is potentially a large task.
Good luck!
