Deleting from the Change Log 

Use

Deleting data from the change log for an ODS object is recommended if several requests, which are no longer required for the delta update and also are no longer used for an initialization from the change log, have already been loaded into the ODS object. If a delta initialization for the update exists in connected data targets, the requests have to be updated first before the respective data can be deleted in the change log.

Only a temporary, limited history is then retained. The change log can possible become so large you might want to reduce the amount of data volume and delete data for a specific time period.

Procedure

Since the change log is also stored as a PSA table, you can use the function for deleting data from the PSA to delete data from the change log.

  1. In the ODS object administration, use the main menu to choose Environment ® Delete Change Log Data.
  2. Proceed further as in Deleting Requests from the PSA.

Or:

  1. Go to the PSA tree.
  2. Use the main menu to choose Settings ® Display Generated Objects, so that you can display the InfoSource for your ODS object. Your InfoSource has the same name as your ODS object, along with the prefix ‘8’.
  3. Use the context menu to choose Delete Change Log Data.
  4. Proceed further as in Deleting Requests from the PSA.
