ADSCDME is a TASK code. You have RESTYPE=TASK secured in the IDMS security table RHDCSRTT that is being used by the CV. If the #SECRTT macro for RESTYPE=TASK has parameter SECBY=INT, then it means there is no Resource CATEGORY defined in the system dictionary that contains this Task Code. For internal TASK security you must define all TASK codes that may be executed in a Resource Category and Grant Execute to all Users who should be allowed to execute the TASKs in that Category.
If you have SECBY=EXT then the TASK resource (determined by EXTCLS and EXTNAME parms on the #SECRTT macro) is not defined in the External Security Manager.
If you secure RESTYPE=TASK then every TASK Code defined to the System via the Sysgen Compiler must be defined and access must be granted to whoever should be allowed to execute the Task in question.
