When using BUILD, take precautionary measures to prevent unexpected loss of control table definitions. You cannot successfully build a privilege unless you add the COMMAND, META ENT, STATUS, DIALOG, and WORKSTATION (entities linked to that privilege) to the control tables. Failure to add the entities noted above prior to the SYSTEM.EXTEND.BUILD command can result in the loss of control data definitions. .
For more information, refer to the documentation on using the build command located here.
