preallocation tock check

Our client want to have check on movement type 999 for preallocation stock.

I have checked wm movement type 999 for the preallocation.

I am confused on the how to create scenario to test this.  Can you please explain how can I test this scenario.

Ok, now I got it, the German titel on that transaction is quite different to preallocated stock, and we are actually not using it at.

As you rightly said, LT51 is used if there is no stock for a material.

999 movement is used to move existing stock between bins.

This sounds pretty contradictory.

why would one maintain a preallocation if you have stock that could directly be used?

why was an existing preallocation not fulfilled when the receipt was done?

why would one ignore the preallocation with the receipt and do it uncertain events like a 999 movement.

The check can be activated to any movement and this check is carried out with the putaway into the destination bin
