FBRA error F5 136 can not reverse the clearing document

After using the function POSTING_INTERFACE_CLEARING in Customized procedure.

I found that the balance of line items processed by the same clearing voucher is not equal to 0.

Using DB02 SQL editor entering the code:

SELECT RBUKRS,AUGDT,AUGBL,RACCT,SUM(HSL),COUNT(*) FROM ACDOCA WHERE XOPVW='X' AND BELNR NOT LIKE 'B%' AND AUGBL<>'' GROUP BY RBUKRS,AUGDT,AUGBL,RACCT HAVING SUM(HSL)<>0

and find some clearing ducuments:

And then I tried to reverse these clearing ducuments error F5 136.

This issue makes the problem that :Open item balance is not equal to account balance.

I have search notes about this error message, but all relevant notes are telling about The cash discount, this has nothing to do with my problem.

Has anyone ever encountered a similar problem? Please let me know and give me some tips.

Thank you so much!
