Hello Team,

Could you please assist me on the below issue.

I am trying to process down payment request , F-47 but I am not getting partner bank field in more data.

I have checked OBC4 and the posting key level field status both are partner bank field is optional.

I have checked one test system which is EHP 7 where I get this field, can you please assist me whether this enhancement issue or anything I am missing.

In advance thanks for your help.
