2.6 LDS Process Flow

This topic explains the process flow for LDS.

• Prepare new LDS environment for LDS processing.
• Create LDS schema equivalent to Business LOB only with Metadata.
• Create Data source in application console for newly maintained LDS schema.
• Maintain corresponding DSN Entries in SMS schema.

1. Launch LDS Module Setup Maintenance(SMDLDMOD) screen and maintain LDS module record using the newly created instance and cut-off date identified for LDS processing.
2. Launch LDS Pre Process(LDPREPRC) screen, and click Preprocess Check button.
   The list of mandatory checks to be cleared before proceeding with LDS process is provided.
3. Click PreProcess LDS button to initiate pre-process execution once the mandatory checks are cleared.
4. Launch LDS Status(LDDVWSTA) screen to monitor status of each activity in Preprocess stage.
5. The system will create LDS Module and also will identify and store the records to be moved to LDS schema and retained in LOB schema after successful preprocess execution.
6. Launch LDS Process(LDPROCES) screen once the preprocess execution is completed successfully and sanity checks are cleared, initiate the following.
   The following activities are initiated:

   • Export LDS Data
   • Export Business Data
   • Truncate Business Data
   • Import Business Data
   • Post Process
7. Launch LDDVWSTA screen to monitor status of each activity in Post process stage.
8. Launch SMDUSRDF screen and create user with view access to LDS module alone.
9. Log in with the newly created user into LDS module.
10. Launch LDPROCES screen and select Import LDS Data and click Execute.
11. Log in using newly created user into LDS module to view LDS screen and reports.

Thus explained the pre-process and post-process execution operation of LDS record.
