Hi Gaurav,
i was going through this thread so i found that while confirmation user has activated tick for final confirmation right.
CATA and CN30 are basically used for identifying the reason for display the pool of incorrect confirmations. please check for difference:
CN30 will display the pool of incorrect confirmations that occured during transfer and which could not be posted. From here, you can select the details of the record and click on check confirmations button to view the error.
Whereas, COFC will contain the error records created because of an issue in actual cost calculations & postings and the same transaction will allow you to post process the actual cost after you fixed the errors.
CATA is used for transfer data from all objects whether related to PS or PM or any other whereas CAT5 is related to only transfer to PS only.
please confirm which process or TCODE is used for confirmation by business.
thanks
Sunil
