How To Fix CNV_10020152 - &1 &2: Lengths of SDetObject &3 and fixed value source object &4 differ

CNV_10020152 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 152

• Message text: &1 &2: Lengths of SDetObject &3 and fixed value source object &4 differ

What causes this issue?

For this DTFLD record, <DS:DE.CNV_10020_FIVAOBJ>fixed value source
object</> &V4& has been assigned to <DS:DE.CNV_10020_DTOBJ_S>source
determination object</> &V3&. (The value given in brackets is the
corresponding allowed number of characters.)
The system found that the length of the source determination object
does not correspond to the length of the fixed value source object.
However this must be the case.

How to fix this error?

The most likely reason for this is that a wrong fixed value source
object has been assigned. Correct the definition accordingly.
