How To Fix AXT_MODEL135 - Field &1: Field length (&2) is not fully used by picklist codes (&3)

SAP Error Message - Details

• Message type: E = Error

• Message class: AXT_MODEL -

• Message number: 135

• Message text: Field &1: Field length (&2) is not fully used by picklist codes (&3)

What causes this issue?

You have specified a field enhancement with a dropdown list.
However, the length of the value codes entered for the dropdown list (
&V3&) is shorter than the length (&V2&) that is defined for the field.
Note that the specified field length does not affect the length of the
description for a dropdown list item. It only controls the length of the
value codes.
If the field length is too long, this might waste database space and
reduces the space available for other enhancement fields.

System Response

A warning is displayed.

How to fix this error?

Consider reducing the field length.
If you are sure that this length is required, for example, if you want
to add more dropdown list items later, you can ignore this warning.

• What is the cause and solution for SAP error message AXT_MODEL135 - Field &1: Field length (&2) is not fully used by picklist codes (&3) ?

  The SAP error message AXT_MODEL135 indicates that there is a mismatch between the defined field length of a specific field and the actual length of the picklist codes associated with that field. This typically occurs in the context of data modeling or configuration in SAP systems, particularly when working with picklists in applications like SAP S/4HANA or SAP Business Technology Platform.
  Cause:
  
  Field Length Mismatch: The field defined in the data model has a specified length (e.g., 10 characters), but the picklist codes being used do not fully utilize this length. For example, if the picklist codes are only 5 characters long, this discrepancy triggers the error.
  Configuration Issues: There may be an issue in the configuration of the data model or the picklist itself, where the codes were not set up correctly to match the expected field length.
  Data Integrity Issues: If the picklist codes were modified or not properly maintained, it could lead to inconsistencies with the expected field length.
  
  Solution:
  
  Review Field Definition: Check the definition of the field in the data model to ensure that the length is appropriate for the picklist codes being used. If necessary, adjust the field length to match the actual length of the picklist codes.
  Update Picklist Codes: If the field length is correct, review the picklist codes to ensure they are defined correctly and utilize the full length of the field. You may need to add or modify codes to ensure they meet the length requirement.
  Data Model Configuration: Ensure that the data model configuration is correct and that all related settings are properly aligned. This may involve checking the configuration settings in the SAP system or consulting with a technical team.
  Testing: After making changes, perform testing to ensure that the error no longer occurs and that the picklist functions as expected.
