I mean to say
When picker goes to the physical location, he gets that physically 6 qty while the picking qty was 10. Then he confirm the TO with 6 qty and 4 qty goes to difference field which resultant 999 for 4 qty.
From system point of view the stock of 4 qty is still in the W/H, so the order can be created by customer. But actually the stock is not there. So our Inventory Audit team goes for cycle count the part and decide the 999 should go back to the location or adjust out.
For this auditing takes times for 2 days, by this time lot of other order appears to the system for that the stock of 4 qty. I want to stop that. I want the stock to be automatically block when it goes to 999.
