Environment

Release : 15.5.1, 15.6, 15.6.1, 15.7, 15.7.1
Component : CA PPM DATA WAREHOUSE

Resolution

This is a known defect: DE52941, fixed in 15.7.1.2 and 15.8

STEPS TO REPRODUCE: 
1. Login to Clarity PPM.
2. Schedule Load Data Warehouse - Incremental to run every hour.
3. Adjust around 10K transactions through WIP adjustment.
4. Post to WIP those adjustments while the Load Data Warehouse job is executing.

Expected Results :- Load Data Warehouse - Incremental shouldn't have any issues.
Actual Results :- Load Data Warehouse - Incremental fails with error ORA-02298: cannot validate (PPM_DWH.DWH_FIN_TRANSACTION_LN_FK1) - parent keys not found when transactions are made whilst the job is running

Workaround: Avoid adjusting WIP transactions when the Incremental Load is running.

Solution: Upgrade to 15.7.1.2 or 15.8 (and higher)
