Message Long Text :
Cause . . . . . : Reference catalog &1 can not be deleted until all its dependent catalogs have been deleted. Recovery . . . : Either specify *DELETE on the DEPIMGCLG parameter to delete the dependent catalogs along with the reference catalog or use the Work with Image Catalogs (WRKIMGCLG) command to see a complete list of dependent catalogs for catalog &1 and delete them, and then try the request again.
