Lock step in multiple instances (referenced process)

Hello everyone, Im new here, hope you can help me.

I´m trying to invoke multiple instances of a Referenced Process. I invoke this referenced process several times correctly, creating multiple instances, but when the first child is executed, the parent instance continues without waiting for the others.

I read “Administering webMethods Process Engine

Hello Hernan.,

once after calling the referenced processes, you should join all theose processes to teh parent process and place a join ‘AND’.
so the parent will wait until the child completes.

Thank you…
