Execute Job won't allow adding material lines apart from default Repair order item.

Hi,Need your help. I have an issue in Depot Repair Job execution.

Scenario 1)  - I create a repair order with Org as 'A'. The logistic lines are created and I create a job as well. I click execute Job and I see the RO material default as material line as well. In addition, I can issue any material to the job.

Scenario 2) - I create a repair order with Org as 'B'. The logistic lines are created and I create a job as well. I click execute Job and I see the RO material default as material line as well. I wanted to issue  material by adding another material line, but the job number does not default and does not show up in list of values.
