Inayas,
In general, Product Allocation searches from the most detailed level until the least detailed level. It searches until it finds a match in CVCs. Once it finds the first match, it then compares the order with the remaining allocation for that specific CVC and renders a pass/fail. Nor further checking is done.
In your case, if your order contains the elements LOC1/US/MAT1/123456/123456789, then it finds the remaining unallocated quantity for that specific CVC and performs the check, and renders a pass/fail. Once the check against that CVC is done, nothing else is checked.
Now, if the order did not contain the elements LOC1/US/MAT1/123456/123456789, but instead it only contained LOC1/US/MAT1/123456/ and 'something else', then it would find the allocation for your 'level 2'. It would then check for remaining allocation for level 2, and render a pass/fail. Once the check for this CVC is done, nothing else is checked.
The system searches from the most detailed level to the least detailed level. If it finds no match between the data contained in the order and any existing CVC, then it renders a failure to confirm based on allocation.
To implement such a scenario should I be looking at Product Allocation procedure sequence??
The above check does not require a sequence. Exactly what scenario do you want to implement?
