Rules for Deleting Objects

Select an object to delete. The object that you are deleting and objects that are deleted because you are deleting the object, must meet these object projection rules:

• The object's maximum access must be Delete. Maximum access is the highest level of protection for an object in the child encyclopedia.
• The object must not be checked out with protection access greater than Read.
• When deleting a modifying association, the maximum access of the associated object must be at least Delete, and the associated object must not be checked out with protection access greater than Read.
• When deleting a referencing association, the maximum access of the associated object must be at least Access, and the associated object must not be checked out with protection access of Deleted.

If the object does not meet these rules, the CSE issues an object protection error when you select it. You can make changes to meet the rules and attempt to delete the object again.

The CSE permits deleting these objects:

• Activity cluster
• Batch Job
• Batch Job step
• Business area
• Business system
• Component model
• Crit success factor
• Current data store
• Current info system
• Data cluster
• Data column
• Data table
• Denormalized column
• Dialect (non–dflt)
• Deletion of non-primary dialog
• Dialog flow
• Entity subtype
• Event
• Environment
• External object
• Facility
• Goal
• Index
• Information need
• Link table
• Location
• Navigation diagram
• Objective
• Online load module
• Operations LIbrary
• Org unit (non-root)
• Performance measure
• Procedure
• Procedure step
• Service Manager
• Screen
• Strategy
• Tablespace
• Tactic
• Type map
• User def matrix
• User-defined object
• Window load module
• z/OS LIbrary

The CSE prevents removing these objects under the conditions listed:
