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.
