PM49696: using specific() perm on object without access to modify parent produces save error

Rational DOORS 9.4

APAR status

• Closed as program error.

Error description

• If you have parent and child objects, and a user has admin
  access to the child, but only read access to the parent, if the
  user uses the specific() perm on the child object, then saves
  the module, an error will be given stating:
  
  '
  error is reading/writing ?module name?
  Unable to save the module - data structure is incorrect.
  
  Please manually copy or export and data you require and discard
  changes in the module.
  consult you system administrator
  '
  
  To recreate:
  
   - setup a parent and child object
   - assign read-only access for a user to the parent
   - assign full admin access for a user to the child
   - open the module as the user in exclusive edit mode and run
  the following DXL (assumes the child has absolute number 2)
  
  '
  Module m = current
  Object o = object 2
  
  specific (o)
  save m
  '
  
  Workaround:
  
   - use the isAccessInherited() perm to determine if there is
  actually any point in using the specific() perm, where access is
  not inherited there is no point.
