Message no. F5808 by SD module

hello experts

Currently, this error code appears in SD transactions, indicating that GL account is a related problem. I think it's a problem with FI. How can I enter it to solve it?

Or I want to know how to solve it!

==========================================

Field Order is a required field for G/L account 3706 501000

Message no. F5808

Diagnosis

The value for field "Order" in the interface to Financial Accounting is an initial value but you are required to make an entry in the field selection for G/L account "501000" in company code "3706" linked to the field selection for posting key "81".

System Response

Error

Procedure

It might be an error in the configuration of the G/L account field selection. The initial application, used to call up the interface must otherwise define a value for field "Order". If this is the case, contact the consultant responsible for the application used to call up the interface or get in contact with SAP directly.
