Issue/Introduction

In IDD, a change is made to a group element which is part of a record that is included in a MAP or a SCHEMA.

Attempting to REPLACE this ELEMENT within the record doesn’t work. It fails with DC601045  "NOT IDD OWNED - ANY CHANGE IS INVALID"

A client has requested a SCHEMA record be changed that is IDD owned.
I added a 'V 2' of the record in IDD.  Then I changed the SCHEMA to SHARE STRUCTURE OF REC V 2 and VALIDATED the SCHEMA.  
Then I try to change the rec in IDD and get the following errors -

MOD REC PCBASIC V 1.

Release: IDMS 19.0

Resolution

In IDD, it is not possible to change a record that is Schema or Map-Owned.
To make any change to a Schema or Map-Owned record, it must be removed from all the schemas and/or maps to which is currently defined before IDD will
allow the record to be changed.

Steps to modify a record that is schema and/or map owned in IDD.

Where n = is the current version number.
Where nn = the new temp version number.

1. In IDD: ' DISPLAY RECORD record-name VERSION n.'
   To produce a cross-reference list for all entities where record is defined.
   
   
2. ' MOD REC record-name VERSION n NEW VERSION IS nn. '
   Now all schema/maps/etc that where pointing to 'record-name VERSION n', point to
   to 'record-name VERSION nn'.
   
   
3. Since 'record-name VERSION n' no longer exists it can be added to the
   dictionary with the desired new structure in IDD.
   'ADD REC record-name VERSION n.' {with the desired new structure]
   
   
4. Modify the schema/maps so that now it points to the newly added 'record-
   name V n' and generate all affected schema/maps/etc
