What causes this issue?

Document item data differs from quantity schedule data. The assigned
factory calendar for the plant (document item -> T001W) differs from
the quantity schedule data and is only for informational purposes.
&SYSTEM RESPONSE&
The quantity schedule is structured based on a specific factory
calendar, which is dependent on the <DS:GLOS.plant>plant</> assignment
(proposal). If no plant is assigned to the document, the system prompts
you to enter a
<DS:GLOS.factory calendar>factory calendar</> for the
quantity schedule.

How to fix this error?

Ignore this information or go to the QS header screen to assign a
different calendar to the quantity schedule. This is only possible if
you can choose the "Restructure" function as one possible
option, i.e. if (no <DS:DE.OIA_SMENGE>follow-on documents</> exist).
&dependencies&
Calendar assignment in plant Table T001W.
