When using a source output library or any output library that is being shipped, make sure that the nodes being used are the same number that is defined in the mapping rules. What this means is that the name of the source output library prefix.qual.sys.sub should be the same as defined in the mapping rules.
Here is an example of a mapping rule in Endevor:
if the actual dataset being used is the following:
the mapped dataset has 4 nodes and actual dataset has 5 nodes. The number of nodes must be equal
in order to use the package ship utility.
