Rules for posting key 15 and acct 75010 set incorrectly for "KOSTL" field

Hello,

I am posting a customer check payment in F-28 but I got the above error. I had checked out all the configuration of both the Gl account & posting key in Field Status Maintainence. The output is as follows:

Rules for posting key 15 and acct 75010 set incorrectly for "KOSTL" field

Message no. F5272

Diagnosis

One of the rules specifies that the field demands a required entry, the other rule says that the field is to be suppressed.

Procedure

Correct one of the two rules for the field selection.

You find the field status group in the G/L account master record:

Execute function

You can find the rules for the field status group in the Financial Accounting Implementation Guide in the activity Maintain field status variants.

You can find the posting key in the Financial Accounting Implementation Guide in the activity

Define posting key.

Please suggest.
