Function documentation Optional Supplementary Segments Locate the document in its SAP Library structure

Use

You define optional supplementary segments in format trees for incoming files to identify a data record that corresponds directly to the previous record, but which is not mandatory in the file.

For instance, a file may contain payments per business partner, and sometimes a note to payee is included with the payment. You represent the payment with a payment segment, and the note to payee with an optional supplementary segment.

Activities

You create a supplementary segment as a normal segment, and assign it a reference ID and the same level as the segment it is to correspond to. Then, in the segment that the supplementary segment corresponds to, you enter the supplementary segment's reference ID on the Opt. Supplem. Segments tab; the system then knows that the two segments belong together.

You also need to enter optional supplementary segments in the assignment rules in the header data.

Example

To illustrate how optional supplementary segments work, refer to the template format tree SAP_EXAMPLE (tree type MCSH). It contains the following segments, with the note to payee being an optional supplementary segment to the payment:

Segment

Reference ID

Level

Header record

HEADER

1

Business partner

BUPA

2

Payment record

PAYM

3

Note to payee

VWZW

3

Trailer

TRAILER

1

Assume your incoming file contains the following data records:

HEADER------------------------------------------------
BUSINESS PARTNER------------------------------
PAYMENT 1-------------------------------------------
PAYMENT 2-------------------------------------------
NOTE TO PAYEE------------------------------------
PAYMENT 3-------------------------------------------

Based on the format tree, the DME Engine reads the payments of the business partner and writes them to the converted file. For payment 2, it recognizes that a note to payee is included, and writes it together with the payment record.
