Hello Spencer,
Thank you for your time and reply.
The issue is a bit tricky.
I'm working on Service Requests, The access sequence used to determine Reporter is from IBase (Contact Person).
Now when I enter IBase in Service Request, I want it to show popup( with all the possible partners determined ) for the first time, but I don't want it to be determined again if I cancel the popup.
Determination time has to be recurring because I don't want it to be determined just when saving or when entering a product.
If I stop the re determination , Reporter would work fine ( It would show the popup once and never after that ) but then my Service Employee Group Partner Function will not be re determined.
I want the re determination to be stopped just for Reporter.
I have tried all the possible options in SPRO.
I cant think of any code change that would make this work.
Please let me know if you have any solution to this.
Thank you again for your time 
.
Regards,
Pratheek
