This is required for reconciliation account. The reconciliation account updated during the create mode should not be changed later on in the change mode. This will create a lot of problem. In the change mode the field should not be available for change. It should be only in the display mode.
To do that I followed the standard Process:
SAP Customizing Implementation Guide-Financial Accounting (New)-Accounts Receivable and Accounts Payable-Customer Accounts-Master Data-Preparations for Creating Customer Master Data-Define Screen Layout per Activity (Customers)
Here In this Screen after getting into my company code. I couldn't find the transaction type "Change Customer(Accounting)" Instead I am getting "Select Group".
How to configure the Screen for this activity??
A Detail help is well appreciated.
