pauls985 , here comes the difficulty..

If the you are capturing only the validation message in sub process, have a process variable of type list in both parent and sub process

Pass the pv as reference to the sub process (or we can have a separate output)
In sub process , add your validation message by appending to it.(here we can either append to the list or add at specific index i.e tp!instanceindex)
In main process we can then process the pv now.

If the variable is cdt, it is not recommended to pass as reference.(we do as pass as reference - not a best practice)

In this case , we have move the flow in main process when each instance completes
Have pv as cdt in input mapping and capture the sub process out when each instance completes.
Have another cdt of (same type as above)list, and in script task append the sub process out put to this list
After script task add wait node , to wait for all instances completes(have a logic to find out all instances completed)

ok so I now have this working and my master proc will start X number of sub procs :)
Each sub proc should perform validation on the data I've passed to it, and Id like it to map to another array within the master proc. So once all the sub procs complete I am left with an array in the master of all the instances where validation failed.
However the return mapping doesn't allow it ? I can map back to a multi entry field - but at run time the last sub instance to run is overwriting the prev instances. So I'm not getting an array ..

I haven't seen anywhere...We have used the same approach in our design...

Brill that was the problem. Out of interest is this documented anywhere ?

pauls985 , in subprocess node inputs, Please map as ..

Subprocess pv = Parent process pv[tp!instanceindex]...you have to hard code tp!instanceindex since it will not be available in expression editor...
