Hello Christine,
The process for unconditional actions is to select each object, therefore each partition of the tablespace and index and also any nonpartitioned index.
You would have to use a (TSP)/(IXP) condition to process the partitions collectively, but you could select a condition that would always trigger e.g.
(TSP) Total number of pages allocated => 0
You may be able to customize your image copy model to ignore partitions > 1 to achieve this too
e.g. add following type test to your model
#IF(%PART,EQ,1)
.... model content here
#ELSE
#ENDIF
This may be problematic as ibm action codes will pick up the step jcl model for each object that is processed.
Regards,
Steve
