User exits in the screens


Additional header data is on screen SAPMV45A 0309, additional item data on screen SAPMV45A 0459. These screens contain the Include screens SAPMV45A 8309 or SAPMV45A 8459 as user exits.

Fields which are also to be included in the sales document for a specific installation should be included on the Include screens for maintaining. If an application-specific check module is needed for the fields, this can be included in the Include MV45AIZZ. The module is called up in the processing logic of the Include screens.

For field transports, you do not have to make changes or adjustments.

Example
A new field, VBAK-ZZKUN, should be included in table VBAK.

If the check is defined via the Dictionary (fixed values or check table) the field must be included with the fullscreen editor in the Include screen SAPMV45A 8309. In this case, no change has to be made to the processing logic.
