Number of error messages due to non-availability
For all materials, the system counts how often error message VL150 is
issued. This error message is issued when the material of the quantity
that has been confirmed in the order is not available during delivery
creation.
Causes
1. Availability checking rule in the order is not as comprehensive as
in the delivery (e.g. with purchase requisitions in the order, no
purchase requisitions in the delivery)
2. Regarding the material, there are orders in which no requirements
are transmitted. If these orders are delivered, they may take away
confirmed quantities from other orders under certain circumstances.
3. In Materials Management, withdrawals have taken place (e.g.
scrapping, inventory difference...)

How to fix this error?

1. Check which reasons apply and, if necessary, correct it.
2. Rescheduling, if necessary (only if 'Quantity/Date' is not fixed in
the order). Note during rescheduling that the program is a long-running
transaction and should only be carried out as a background job.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
