Substitution on complete document level - Error
I'm trying to create a substitution step on complete document but I have the following error:
You may not substitute any fields for this Event
Message no. GB175
Although substitutions are permitted for the boolesche class 15 (application area FI, Event 0003), the application did not release any field for substitution.
Processing is terminated. You cannot change any field for this Event (even within a substitution exit). Defining a substitute therefore makes no sense.
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.
I read the OSS SAP notes but I didn't undestand how to proceed.
Thanks a lot
