You can use certain criteria (such as a specific period or user) to search for data that was changed in the system. The data that is found in this way is sorted by table logs and change documents, and displayed in the form of a list. In this way, you can trace the change history of certain data, and therefore perform an evaluation of the data in the system that complies with GxP.

To search change documents, the corresponding transactions must be linked with the "change document creation" function, and they must be active. In addition, logging must be active for the table fields containing changed data.

For the system to be able to display the results of the evaluation, in authorization object C_AUT_TCD you must have the authorization for the transactions in which changes were made. If you do not, the system cannot display the full results.

There are two modes for performing an evaluation: standard mode and extended mode. When you start the transaction, standard mode is called up initially.

In both modes, you first enter the selection requirements that you want the system to use to search for changed data. Selection conditions can include:

• Date and time of change
• Person who changed the data
• Transaction code used to make the change

Once you start the search function, the system finds all the data that meets the selection conditions, and displays this information in list form. If you double click on a list entry, you can display detailed information for this entry, such as the exact time of the change, the changed data value, the person who made the change, and so on.

You do not require much technical knowledge to enter selection conditions in standard mode. However, evaluation takes longer in this mode because you do not enter many selection conditions, and the system therefore searches an extensive dataset.

Selection conditions in standard mode include:

• Date and time period in which a change was made. This is a required entry.

• Name of the user who made a change to the data.
• Transaction to which a changed table or change document object was assigned. This is a required entry, but you can also enter a placeholder (such as ‘*‘).

You also have the following additional search options:

• Long text

• Evaluate details

In extended mode, you have not only the selection conditions available in standard mode, but also a whole series of other selection conditions which you can use to define the search for changed data. This can reduce the evaluation time considerably. To enter the additional selection conditions effectively, however, you require more in-depth technical knowledge of the processes and links in the logging functions of the SAP System.

There are four additional variants available for evaluation in extended mode:

• Only take account of change document objects
• Only search in table logs
• Search in change document objects and table logs
• Search in long texts

You select an evaluation variant by entering the selection conditions on the relevant tab page.

When evaluating table logs and change documents, you can use the following conditions to limit selection in addition to those available for standard mode:

• Type of change (Insert, Update or Delete): only newly inserted, updated or deleted are searched:

• inserted: a new data record was added to a table.
• updated: the data value in a table field was changed.
• deleted: a data record was deleted from a table.

• Table name: technical name of the table you want to evaluate. The system only searches in the table you enter.
• Table field: technical name of the table fields you want to evaluate. The system only searches in the table fields you enter.

If you only want the system to search in table logs, on the Table logs tab page you can enter the table keys of the table you want to evaluate.

If you only want the system to search for change document objects, you can also enter the following conditions:

• Change document number: the number under which the change document is stored
• Object value
• Change document object: technical name of the change document object
• Table key: the key of the changed data record

If you want to perform a combined search for change document objects and table logs, the selection criteria mentioned above for variants 1 and 2 are available on the relevant tab page.

If you want to evaluate long text logs, you can enter the following selection conditions in addition to those available for standard mode:

• Text object: describes the application object belonging to the text
• Text ID: more detailed specification of the text object
• Text name: together with the text object and text ID, identifies the text.

Once you have entered all the selection conditions, the following options are available to you:

• Copy current selection conditions and enter further combinations of selection conditions
• Delete current selection conditions, most recently copied selection conditions, or all copied selection conditions
• Display a list of all selection conditions copied so far
• Display number of hits for the current selection criteria

• Save or import own selection conditions as a variant.

You can delete selection conditions that you have already copied to the system at different levels:

• Delete current selection: the current selection conditions displayed on the screen are deleted (in standard and extended mode)
• Delete last copied selection: the selection conditions most recently copied to temporary storage are deleted (extended mode only)
• Delete complete selection: All selection criteria are deleted from temporary storage (extended mode only)

Choose Display selection conditions to list all selection conditions that you have written to temporary storage with the Copy selection function since the last evaluation, sorted according to the sequence of your entries.

Before the actual evaluation, you can use the Number of entries function to check how many logs exist for the current selection conditions, to decide whether you need to reduce the number of logs by entering further selection conditions.

This check does not take account of authorizations and client dependencies. Therefore, it is possible that fewer table logs and change document are included in the actual evaluation than were determined during the Number of entries check.

You can save a group of selection conditions as a separate variant, and quickly access it using Get variant. If you have created a variant, the Evaluation of Audit Trail function (AUT10) starts immediately in extended mode (otherwise in standard mode).

• 140: for change document objects and table logs
• 150: for table logs only
• 160: for change document objects only
• 170: for long texts only

The following prerequisites must be met before an evaluation can be run as a background job:

• You have entered AUT_REP10 as the name of the program that is to be processed in the background.
• The selection conditions must be stored as a variant. This must relate to one of the selection screens 140, 150, 160 or 170.

Long texts cannot be displayed in this type of evaluation
