How To Fix GTR_MF038 - Assignment of field &1 is not possible (see long text)

GTR_MF038 - Overview

• Message type: E = Error

• Message class: GTR_MF - Multifunding Message Class

• Message number: 038

• Message text: Assignment of field &1 is not possible (see long text)

What causes this issue?

Assignment of field &V1& is not possible, for one of the following
reasons.
You entered a customer-defined field and it has no runtime class
assigned. The runtime class is important to get the field value during
runtime to evaluate the condition.
You entered a field to an existing program profile assignment where
multi-funding rules with conditions exist. This is not possible as long
as Conditions exist with the previous fields. When adding new field, the
fields would be initial for the conditions -> this could cause
inconsistencies because condition fields are always required.

System Response

Processing canceled.

How to fix this error?

If you entered a customer-defined field without assigned runtime class,
go to the IMG step <DS:SIMG.SIMG_GMGTR_CUSTSPEC>Maintain
Customer-Specific Condition Fields</> and make the assignment.
