CHANGEDOCUMENT_READ_POSITIONS - Change document: Read change document items

BAL Application Log Documentation   PERFORM Short Reference  
This documentation is copyright by SAP AG.

This function module reads change document items and processes both the old and the new values according to their category. In some cases, the units and currencies are added on to the value fields. The appropriate table header is also determined.

The change document number is required as a minimum entry.

Performance notes:

Access to change document items is made quicker if the function module CHANGEDOCUMENT_READ_HEADERS was already used to read the associated header details.

If the function module CHANGEDOCUMENT_READ_POS is called directly after the function module CHANGEDOCUMENT_READ_HEADERS is called (with a change document number found there), the number can be read from the internal data filled in CHANGEDOCUMENT_READ_HEADERS.

If possible, do not use wild cards in the parameter values.

The program RSSCD100 uses this function module and is a possible application.

Here, the header details are also read first and then the associated items.

Example call:

DATA: NUMMER LIKE CDPOS-CHANGNR,
TABNAME LIKE CDPOS-TABNAME,
TABKEY LIKE CDPOS-TABKEY.

DATA: BEGIN OF EDIT_FORM OCCURS 50.
INCLUDE STRUCTURE CDSHW.
DATA: END OF EDIT_FORM.

...
