hello everyone! We have a requirement that only the original journal creators and assigned approver can edit a Journal Entry. I have tried using the lock Record action in WFs but unfortunately, I am having trouble formulationg the condition that will allow this. do you have any ideas on how do this?

Might need to create a custom field to store the created by But then your condition is User is none of Next Approver AND User is none of Createed by

Yes, those exactly are the conditions i created. I got the workflow running now by adding AND which i did not put before. I was wondering why it worked now, don't workflows default to AND when not using expressions?

Yes that is strange...usually if you don't use expressions Netsuite assumes "AND"
