Redefine the Owner and Member List

When creating a User Defined Element Type (UDET) by default it will inherit the same allowed member types (UDMLIS) and allowed owner types (UDOLIS) as it's base type. These lists may be reset.

The types in the new list must be either:

• a system type allowed on the base type.

• a UDET derived from a system type allowed on the base type.

Based on the previous example create a UDET named MYBOX based on a system type BOX.

At the command line type 'Q UDLIST' to see the current owner list as follows:

EQUI STRU PTRA SUBE SUBS TMPL

At the command line type 'Q UDMLIST' to see the current member list as follows:

NBOX NPOLYH NCYL NSLC NSNO NDlS NCON NPYR NCTO NRTO NXTR NREV

Both lists may be completely redefined or the keywords 'ADD' or 'REMOVE' may be used to add or remove particular entries.

The following example shows this functionality in a session:

The allowed owner list and member list for a UDET may be any system types allowed on the BASETY, plus any UDET based on these system types. In the example for :MYBOX the user could not add a ZONE to UDOLIST, or an EQUI to UDMLIST because the system type BOX of which the UDET is based does not allow this.

Another example would be a :MYBOX can only go under a SUBE, and that another UDET named :MYNBOX can only go under :MYBOX or BOX and is achieved as follows:

For the :MYBOX UDET:

UDOLIST SUBE UDMLIST :MYNBOX

For the :MYNBOX UDET:

UDOLIST :MYBOX BOX

Changing the allowed owners/members for a UDET could invalidate some existing instances. These are reported as warnings in the Database Integrity Checker (DICE).
