When an orchestration calls another orchestration with an ITERATION step in it doesn't return result

Orchestration-A calls orchestration B.

Orchestration B is having a ITERATE step. Say, there is an ITERATE over a Rule, and there are a few steps on the "True" side of that rule.

Once Orchestrator- A is executed, Result of Orchestration-B is not returned to Orchestration A - specifically the information inside the Iteration/loop on the Orchestration-B

It was working on previous toll 9.2.4.

Now its 9.2.5.6- Any one has experienced this??

How to replicate

----------------

Create an orch B (input - Sales order Number)

Step1: create a data request on F4211 - For a sales Order from F4211 get all Items(ITM) for all lines under that order. Load result on a Data Set variable
