R20 SOURCE(FIELDS) member is missing DB2V12 fields. Should there be DB2V12 fields in this member? Was something missed during the customization phase of the install?
HGHLVL.SOURCE(FIELDS) is outdated. The FIELDS member used to be generated using some batch job but that changed. Now Insight to automatically generates the fields. The current fields are in the online help. All the fields are described in the online help. For example, if you know a field name, you can do a "Find" for it in the FIELDS member. In the online help, you need to know which IFCID record it is a part of. Then you can see the details about it based on the IFCID.
