MDRD121 - Overview

• Message type: E = Error

• Message class: MDRD - Messages for Delivery Relationships

• Message number: 121

• Message text: Delivery relationship was determined automatically, maintenance possible

What causes this issue?

The selected <DS:GLOS.8F1666FFD6F0DB468B7643C63EECC977>delivery
relationship</> was determined automatically using method '&V1&'.
Delivery relationships can be determined using different methods (for
example, existing documents - method '1', customer-specific method -
method 'X').

System Response

The delivery relationship can be maintained manually. If you change and
save the delivery relationship manually, the system changes the method
for the current delivery relationship to manual maintenance - method
'M'. If the delivery relationship is determined automatically at a later
point in time, it will be redetermined according to the method defined
in Customizing. The manual changes will be overwritten.

How to fix this error?

If you do not want a delivery relationship that was entered manually to
be overwritten by a new automatic determination, you can set this in the
program for determining delivery relationships (transaction
<DS:TRAN.WDRD1>WDRD1</>).

Procedure for System Administrators

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