Incorrect accounting document & PC being picked for LI rental postings

Hi Experts,

Currently I'm faicng an issue in my project wherein when I'm doing the LI postings (posting transaction used is RERAPP) for a specific LI contract type ZBE6, contracts are picking a wrong PC and showing the accounting doc type as AB instead of K1 in FBL3N.

However, the LI postings for another LI contract type ZBE5 is picking the correct PC & showing the correct accounting doc type in FBL3N.

Should I reverse the rental postings for the contract type ZBE6 and re-do the postings. or else is there any other method to fix the wrong accounting doc generated & wrong PC being picked for contract types ZBE6.

Thanks & Regards
