ITS ERROR WF COMPLETE ACTIVITY ERROR Ora-20002: 3133: Activity Instance 'Ship_line' Is Not A Notified Activity
This error occur for few reasons
1. if any of line that is eligible for ITS process(oe_interfaced_flag = N) is not in NOTIFIED status.
2.If line is processed by ITS is part of the fulfillment set and some of the lines in that fulfillment set are not in NOTIFIED status.
When I say not in NOTIFIED status , FROM Order Management prospect I mean NOTIFIED status for SHIP_LINE activity. But same is true if you are using Stand alone workflow and you are getting thsi error.Ny Saying this I mean , the activity that workflow is expecting to be in NOTIFOED status is not NOTIFIOED.
Solution to this is
Correct the line back to NOTIFIED status if possible , other wise try to bypass it.
