Got great help from John Laird at Tidal support - Thank you John!!! and problem is fixed - here is his answer:
Yes, I found out that this was added in 8.5x support. There is now a parameter which you can set the retention through Tidal. The default is 7 days. Just add it to the connection options tab in the configuration parameters. Disable/enable when you get a chance to ensure the new configuration takes effect. The following is the parameter to add to the configuration parameter.
RETENTIONDAYS=<#ofdays>
RETENTIONDAYS | 7 | The number of days the process result is viewable in PeopleSoft Process Monitor before it is purged by Process Scheduler. The value populates the PeopleTools table field SPRCSQUE.PT_RETENTION_DAYS at runtime. |
