Change Logging Settings for Data Elements
Data elements can be logged via changed documents if they are connected up with the change document creation process. In transaction S_AUT10, you can determine whether or not a data element is logged via the change document creation facility.
If the Logging checkbox has been selected for the data element, the latter is logged via a change document. You can deactivate logging for the data element by unchecking the box.
You can invoke the function for setting up the logging of data elements either by selecting a certain table or directly via the desired data element.
If no change document object exists for the selected table, the system issues an appropriate warning message. In such case, changing the logging settings for this data element has no effect. Use in non-registered change document objects constitutes an exception to this.
If you change the logging settings for a data element, this takes effect across the whole system on all table fields that are based on this data element.
When you save the changed setting, the system first creates an inactive version of the changed data element. Only when you activate the settings do you generate an active version of the changed logging setting.
To be able to carry out the logging of a data element, the latter must be connected to the change document creation facility (see Creation of Change Documents).
You can only change the logging setting if the selected data element is not locked by another user or request.

Enter the technical name of the table and choose Continue.
The data elements of the table are displayed in the right-hand part of the screen.
Select the desired data element and choose the Use in Change Document Objects pushbutton to determine the change document objects in which the data elements are used.
With the where-used list, the system determines which tables use the data element in question. However, it only checks those tables that are also assigned to a change document object. In the check with regard to change document objects, only registered change document objects are recorded, which means those that were created with transaction SCDO.
As a result of the check, the system lists the tables and table fields plus the change document object in which the selected data element is used.
NotePerform the where-used list function before each change to the logging setting to determine possible effects on other tables.
