Hey Guys, Any idea why AND gateway is getting stuck at second instance.

Please make sure that again to initiate, both the Paths should be reaching this gate, Else i will be waiting for the second one.

(AND gate)it * will be waiting for the second path ...sorry for the typo

It seems like you've got more than just the two flows running down the two webservce call paths. Try right clicking on the XORs before the webservice calls and having a look at how many instances of each there are; no doubt there'll be more than one instance of at least one of them.

I feel like you are making things more complicated than necessary. Since you only need to either Create or Update the TRAMS AJAX POST, just one way or another. Why don't you use one XOR gateway instead of an AND + two XORs? Then at the end of the 2 paths, you won't need the dummy Script Task + AND join, just draw the arrows from both "Check Step Count" and "Check StepCountUpdate" directly into Check for Error.

@ricky: Don't make any decision gateways (OR / AND) to have two incoming flows .. even if it is supported as per documentation, it works for first time however will stop working on the second encounter (in a loop) .. we have faced this issue earlier .. Instead, put a dummy / pass through script activity to intake all the inputs (2 or more) and the output of script activity should be connected to the AND as input .. So, all decision gateway will have one incoming flow and 1 or more out going flow .. Hope I am clear ..

Instead of script task can we also have Complex gate to join all inputs and set 1 incoming Path and define 1 outgoing path to the following XOR gateway?

Has the behavior of XOR gateway been the same on latest Appian 17.1

insert a blank script task before the AND gateway and join the two flows coming from the two dummy script tasks into that. then the output from the blank script task can be feeded to the input of the and gateway.....all gateways except complex gateway can only have one input flow coming in....otherwise they will get stuck

Agree, those ANDs are not required, only one XOR can do the job.
