Lockbox issue - F5 263 The difference is too large for clearing

Hi,

I have a lockbox issue for BAI2 format. When i try to process it FLB2 in BAI2 format with Invoice Search by 1 (Document Numbers), system identifies the customer and document but throws the error message "Accounts receivable posting Error: (F5 263) The difference is too large for clearing"

Below is the BAI2 file that is processed.

Below (also attached for better picture) are the screenshots of the FLB2 transaction. It has posted 'On Account" but did not clear it automatically.

From my analysis above from the BAI2 file, I believe that error is in record 4 because if you see below, it gives Check Amount 501.98 (which i believe is record 6) and Advice Total is 1.98 (Record 4). my understanding is system identifies the check amount in record 6 as 501.98 and identifies invoice # (5555555555) but tries to clear it with 01.98. It starts counting amount as 01.98 instead of 501.98. I contacted bank to see if the file is wrong but they have said file is in correct format as below

4001001601955555555550000050198          0000000000          0000000000                

4 - Constant

001- Batch Number

001 - Transaction Sequence Number

6 - Constant

01 - Overflow sequence #

9 - Overflow indicator

5555555555 - Invoice Supplementary Key (Invoice #)

0000050198 - Invoice Supplementary Key (Invoice Amount)

The last two elements invoice # and amount can be repeated multiple times if there are multiple invoices being cleared

Now since bank confirmed clearly the format is fine and since FLB2 is standard tcode, is there any issue in the way it is being processed

FYI, to see how it runs, I added an extra zero (00000050198) to above file in record 4 and tried to do a test run and it successfully picked the document and cleared it but since bank says the file will be 1 zero less, Is there anything that i am missing
