You need a more detailed description of an acid, and the current 32 bytes of the NAME field of an acid is not sufficient.
Before you consider to add a new User-defined extra field in the FDT, is there a possibility to expand the NAME field of an acid to be larger than 32 bytes? For example 50 bytes.
Is there any option of usermod or FDT-update?
There is no way to expand NAME field, because it is part of security record and cannot be expanded.
The only way to add user description is either to use the INSTDATA field or create user FDT fields.
