• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 044

• Message text: Elem. rel. &1: Length of det. obj. &2 is less than fixed value object &3

What causes this issue?

During the definition of the elementary relationship &V1&, determination
object &V2& was assigned fixed value object &V3& (the number in brackets
is the length/ number of characters).
The length of the determination object is less than the length of the

• The SAP error message CNV_10020044 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a mismatch in the length of a field in the source data compared to the expected length defined in the target structure.
  
  Cause:
  The error message can be broken down as follows:
  
  Elem. rel. &1: This refers to the element or field in the data structure that is causing the issue.
  Length of det. obj. &2: This indicates the actual length of the data object in the source data.
  Fixed value object &3: This refers to the expected length defined in the target structure.
  
  The error occurs when the length of the data being migrated (det. obj.) is shorter than the required length defined in the target structure (fixed value object). This can happen due to:
  
  Incorrect data mapping or transformation rules.
  Source data not conforming
