2992710 - Unable to decrease the length of a published custom field - Custom Fields


  • You're trying to decrease the length of a published custom field but are unable to save it.
  • Pop-up error is seen on saving with the following messages:
    • Field cannot be saved. Correct invalid entries first.
    • Field length must not be decreased. 


  • SAP S/4HANA Cloud
  • Custom Fields app


This is the expected behavior.


  • The field length cannot be decreased once a field is published.
  • As stated in the SAP Help Portal documentation "When you publish a field with a certain length, you cannot decrease the field length later on."

If this is a feature that you would really need, we would like to invite you to participate in the SAP Customer Influence initiative.
