Avoiding Tolerance For Amount Limits For Debit Posting

Hello Gurus,

Please provide your inputs for the below scenario:

According to the standard customization setting we can "maintain the tolerance groups for amount limits and can assign users", while doing manual posting via "FPE1" for example.

However, this restriction is for both debit and credit posting.

In my case my client is looking for the restriction for credit postings only, not for debit postings.

I have found that, while doing posting, FM FKK_AMOUNT_TOL_CHECK” & FM “FKK_DOCUMENT_TOL_CHECK, checks the rule we created at customizing, and restricts users for doing the postings as per the rule.

Please suggest the event where I can modify the standard check according to my requirement, as I don't see implicit enhancement is right option for avoiding the check for debit postings? Or we should follow any other way?

Thanks

Anurag
