BAI2 file format- 4 record

Hello SAP Folks-

I have a question I can't find an answer too: What should be in the Overflow type field? A 6 or a 4? When is it appropriate to use a 6 or a 4 in that field? I have 2 BAI2 file records coming from 2 different banks and one uses a 4 and the other user a 6 in this field.

I understood that it should always be a 6. I don't know when or why you would use a 4 or perhaps it doesn't matter?

Please clarify anyone if you can.
