MT940 EBS Interpretation algorithm 015 (Assignment Number) error Difference too large for clearing

[former_member705087]

Hello Experts,

I have searched various forums but couldn't get a solution for my issue. Hence I am posting this question.

My system gets an MT940 from the bank to clear customer open items. I have made the below configuration in OT83.

Rule AVCI 1 is supposed to debit the cheque incoming account and clear the customer sub gl account based on the assignment number given in the bank statement

Here is my MT940 statement

:20:202010209
:25:10000002
:28C:26
:60F:C201009GBP104799,00
:61:2010091009C300,00FCHI0910202001//0910202001
:86:999/0910202001
:62F:C201009GBP105099,00

Here is my customer open item with assignment field having the value 0910202001

When I process this statement in FF_5, I get the error "difference is too large for clearing". Posting is failing in both the areas 1 and 2.

Note that I have given the BELNR range in FF_5 selection paramters.

However the program is not able to identify the customer open item based on the ZUONR value.

Please help.
