Data Model: Performing Consistency Checks
Data models can be checked for consistency. To do so, there are four check variants available (more information: Consistency Checks: Variants).
To display the screen
Check Consistency of Data Models, choose
Utilities 
Consistency Checks 
in the data model definition or the hierarchy.
To carry out consistency checks, proceed as follows:
-
Define the data models to be checked.
You can check a single data model or a set of data models. By default, the name of the data model from which you called the screen Check Consistency of Data Models is the first value in the selection line Data model. Just as in the ABAP Repository Information System, you can select a certain set of data models here.
You also have the option of selecting the models to be checked from the data model hierarchy and proceeding by choosing
Utilities Consistency Checks . On the
Check Consistency of Data Models screen, you can display the list of
data models previously selected by choosing the arrow pushbutton
=> and making changes if required. -
Specify whether the set of data models to be checked contains only application models, only business objects, or both.
-
Select the checks to be performed. You can select any combination of the four checks by selecting them:
-
All checks: All four checks are performed.
-
Check: Completeness
-
Check: Existence of Predecessors
-
Check: Connectivity
-
Check: Check: Existence of hierarchy_obj.
-
-
Choose Execute or Execute and Print to perform the consistency checks and obtain the check log.
If you choose Execute, the check log will be output only to the screen. If you select Execute + Print, you can specify a printer to which you wish to send a printout of the log.
The check log could be very long, depending on the number of data models checked.
