Physical stock transfer from same plant not supported

What causes this issue?

You have set the special procurement indicator for a
<GL:stock_transfer>stock transfer</>, but the internal plant from which
the material is to be procured is the same plant that is to receive the
material and for which the <GL:quota_arrangement>quota arrangement</>
is valid.

How to fix this error?

Is the procurement plant in the item correct?

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

Have you entered the correct plant on the initial screen for the quota
arrangement? This is the plant that is to receive the material.
