What causes this issue?

Specific items in the document refer to another document with qty.
schedules, e.g. purchase order items with reference to a contract. Qty.
schedules already exist for these contracts, but not for the items of
the document. The structure of the quantity schedule depends on the
document type table in the application.
The <DS:GLOS.release order>call-off</> updates the called-off quantity
in the relevant contract scheduling line by using the
<DS:GLOS.delivery_date>delivery date</>.
The update is not dependent on the QS permission indicator for the
document type, and thus the update is constant.
