Reading and Editing Change Documents 

For these tasks, you have three function groups available:

Function Group SCD1

You can determine change documents using the function modules of this function group.

●      CHANGEDOCUMENT_READ_HEADERS

This function module determines the change document numbers with the corresponding header information for a particular change document object. The search can be limited by specifying various parameters (changed by, date, time). You can implement this function module both in the database as well as in the archive.

●      CHANGEDOCUMENT_READ_POSITIONS

This function module reads the change document items for a particular change document number belonging to a change document object and then prepares the old and new values in accordance with their type. You can implement this function module both in the database as well as in the archive.

●      CHANGEDOCUMENT_PREPARE_DISPLAY

The function module prepares previously read change document items.

●      CHANGEDOCUMENT_PREPARE_POS

With this function module, you prepare a previously read change document item for print.

●      CHANGEDOCUMENT_READ_HDRS_ONLY

This function module determines change document numbers with the corresponding header information for an object class. This search process can be limited by specifying various parameters.

●      CHANGEDOCUMENT_UNICODE_CHECK

This function module tests whether the change document was written in UNICODE-enabled form.

●      CHANGEDOCU_ARCHIVE_HANDLE_SET

This function module is for setting the archive handle globally.

●      CHANGEDOCU_CDPOS_READ

Reads the table [P]CDPOS with TABKEY.

●      CHANGEDOCU_GET_VERSION_TABLES

Gets (P)CDHDR information for reading the (P)CDPOS_UID/_STR.

●      CHANGEDOCU_GUID_READ

Reads the table [P]CDPOS_UID with TABKEY.

●      CHANGEDOCU_HAS_GUID

Tests whether the GUID is used in the object.

●      CHANGEDOCU_READ_POS_W_UID

Reads [p]cdpos and [p]cdpos_uid.

●      CHANGEDOCU_READ_PREP_POS_W_UID

Reads CDPOS and CDPOS_UID with partial preparation of the CDHDR fields.

●      CHANGEDOCU_STR_READ

Reads the table [P]CDPOS_STR with TABKEY.

 

Function Group SCD2

Using the function module of this group, you can prepare change documents specifically for an object class.

●      CHANGEDOCUMENT_READ

With this function module, you read change document headers and the corresponding items for a particular object class and prepare the old and new values in accordance with their type. The search can be limited by specifying various parameters (changed by, date, time). You can implement this function module both in the database as well as in the archive.

●      CHANGEDOCUMENT_READ_RANGES

This function module reads change document headers and items, and prepares the old and new values in accordance with their type. If necessary, the units and currencies are added for value fields.

Range tables are passed to the function module. These must be filled correctly.
If all the range tables are empty, no data is read.
