If it fails with the Sales order parameter = Yes then they set it to No and that will fix the problem and vice versa - no rhyme or reason. Sometimes on AN2 or AN3 view. This is not duplicable in Test only PROD. Sometimes they rebuild all snapshots - no recent RDBMS upgrades - seeing this error 5-6 times per month. Started about 6 months ago


STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run data collections
2. Intermittently PDP concurrent request fails with multiple errors
3. Set PDP sales order parameter to opposite setting and rerun collections to get successful collections run
