New fields in Requests/Accounting Documents 
Requests are saved as parked documents or accounting documents. Some new fields were added in order to fulfill industry-specific requirements:
Posting date (document header)
The posting date can be defined in the system’s Customizing, when using the system for the first time, is subsequently determined and updated again at each day-end closing. The system places the posting date in the document header for every accounting document. Besides this, the system marks the document as an actual posting, if there are cash-relevant FI G/L accounts in the document. For more information, see the documentation on the program Posting date closing (RFFMKTABS).
Document category (document header)
Requests are classified from the document category (payment requests, acceptance requests etc.)
Reason for deduction (document header)
The deduction reason can be defined for requests, so that it can be understood later why the deduction was made. Deduction reasons are defined in Customizing.
Region
The region is a further classification characteristic. Requests can be assigned, for example, to different areas, using the assignment to regions. This makes corresponding evaluations possible. Regions are defined in Customizing.
Reason for reversal (document header)
If you reverse requests and specify the reversal reason in the document, it can be understood later why this reversal was executed.
Preliminary poster (document header)
The user who parked the request is noted in the accounting document, that is, in the posted request. This field is available in the standard from 4.0A.
Commitment item (secondary index G/L accounts (BSIS, BSAS))
The index mentioned above was extended by the commitment item (FIPEX) in order to make related evaluations possible.
File number
You can allocate a file number on the header level of an FI document, in the request. This is a manual field and can be assigned freely. The system does not carry out any checks for this.
