No posting. No entry with key BAI 738 + in T028G

Hello Everyone,

I am getting the error "No posting. No entry with key BAI 738 + in T028G" while loading the EBS file. I had configured the External transaction type 738 as a Debit (Outgoing) transaction. Even the Bank says it is correct. But, I am not sure why SAP system is treating 738 as '+' transaction. Can you anyone let me know if you have faced this kind of error?

Thank You.
