Both JR and JI Transactions are related to JobOps. A JI Transaction (Positive Qty or Negative Quantity); is related to the Issue of Material Into a Job Ticket. You can issue to a Work Ticket, then Unissue from a Work ticket (so the Qty can be negative or positive... Most often it is a negative issue from inventory count). JI transactions are usually a component of the manufactured item. The JR Transaction is when the PARENT Item is Manufactured and Put into Stock (Received into Stock); even in a Make to Order scenario, the IM_ItemTransaction File will show you the JR transaction (then a SO Invoice to take it out). Let me know if you have further questions or if I can help.
