SAP Error Message - Details

• Message type: E = Error

• Message class: GB - Messages used by the Boolean code generator

• Message number: 175

• Message text: You may not substitute any fields for this Event

What causes this issue?

Although substitutions are permitted for the boolesche class &V1&
(application area &V2&, Event &V3&), the application did not release
any field for substitution.

System Response

Processing is terminated. You cannot change any field for this Event
(even within a substitution exit). Defining a substitute therefore
makes no sense.

How to fix this error?

If the substitution is a substitution belonging to the FI application
component, you can release fields for substitution (as described in OSS
note 42615). Note that for most fields, this action implies a
modification to the SAP standard system.
