How To Fix CNV_10020128 - Elem. rel. &1: Determ. with fixed val. obj. as source obj. not possible

CNV_10020128 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 128

• Message text: Elem. rel. &1: Determ. with fixed val. obj. as source obj. not possible

What causes this issue?

Fixed value object &V2& has been stored as the source object for
elementary relationship &V1&. This is not allowed.

How to fix this error?

Determination using a fixed value object as the source object will
always lead to the same target value. Enter this target value in a
fixed object value, and assign it as the target object to a
determination path (if you want to delimit by the source object).
If no delimitation is planned, you can also assign the fixed value
object directly in table CNV_10020_DTFLD as the source object without
specifying a path.
