Purpose
This program is a tool of thesearch engine service. Itis to be used for system administration and can be executed in thedialog or in the background.
You can use this program to delete change pointers.

Integration
For business objects that use the search engine service, a changepointer is generated every time an object is changed. The changepointers in the search engine service therefore represent events. Theyare the basis for delta indexing. For more information about deltaindexing, see the documentation of the indexing programCOM_SE_DISPATCHER.
During delta indexing, the evaluated change pointers are not deletedimmediately. Instead, their status is changed from 1 = Initial to2 = Processed. This means that they can be reactivated ifrequired. For more information, see the documentation of the programCOM_SE_CPOINTER_REACTIVATE.
The most important reason for the reactivation of change pointers is thereconstruction of the search engine indexes based on a data backup ofthe search engine. The change pointers of the search engine service cantherefore be deleted as soon as their time stamp is after a data backupof the search engine.

Prerequisites
None.

Features
This program only deletes entries in the database table COM_SE_CPOINTERin which the change pointers are stored. The program does notcommunicate with the search engine or the application from which thebusiness objects in question have come.
The selected change pointers are deleted no matter what their processingstatus.

Selection
Specify the date up to which the change pointers are to be deleted. Thedate is interpreted by the system in accordance withUTC. It corresponds to thetime zone "Greenwich Mean Time" (GMT).
For safety reasons, the default value on the selection screen is thelast day of the year before last.
If required, you can restrict the program run to a business object andan object type contained in this business object.

Output
You receive a confirmation of your selection and the number of changepointers deleted.

Example
If you backup the data in your search engine once a week, you can deletethe change pointers of the search engine service up to the beginning ofthe previous month with a monthly backgroundjob.##################################################################
