Booking A Back To Back Sales Order Moves Lines To "Awaiting Supply"

 Hi

The issue can be reproduced at will with the following steps in 12.1.1
1. Define an Item code for B2B ordering
a. Purchased Item
b. Build in WIP - Enabled
c. Make or Buy - BUY
d. Customer Orders Enabled =Y
e. Assemble to Order = Y

2. Create a Sales order and Book the same.
3. Check line status. The status shows "Awaiting Supply"

It should have been 'Supply Eligible' to progress the order further

Note 757923.1 already referred.In the site level,MRP: Default Sourcing Assignment has a value which I dont want to change

Best regards

Vinod
