Synchronous Processing in NER

Hello All,

I am trying to call multiple BSFN's in a single NER.

So in one of the BSFN a UBE is getting called, and it is taking some time to process it.

Also this UBE will update the status, and this status should be passed to the next BSFN as input.

But in the NER, the next business functions is not waiting untill the UBE gets completed and thereby this business process is not getting completed.

Is there any synchronous processing in NER?

or any other process to resolve this issue.

I thought of using sleep BSFN, but this might slow down the performance.
