Manually Creating and Editing Message Control Records 
Use
You can manually create and edit message control records (NAST records) for agency documents to enable you to select parameters, such as message type or communication parameters, that are not defined in Customizing for message determination.
Prerequisites
It must be possible to process the agency document in change mode (for example, documents that have not yet been transferred to Financial Accounting).
Procedure
The agency document is displayed in change mode.
You go to a list that displays the NAST records created for the document.
You can enter the following parameters:

If you create a NAST record manually, you must also enter an archiving mode (such as Print only) for the message under the Communication method. You can also maintain additional data such as the time when the message is to be sent.
