Hello, I would like to implement a "set" data structure in appian.  My use case prefers a "set" data structure as opposed to a list or dictionaries, because a set only contains unique values, or in my use case, unique sets.  I tried to search in the documentation, but to no avail. 

Hi, In our application users have initiated actions many times to upload a file due to some integration issue for file upload. Issue has been resolved. Now the support guys have been asked to trigger the instances from Monitoring. Now the problem is if we trigger blindly without seeing we may end up running multiple instances for same file upload and it may lead to file duplicate issue in the integrated system. Could someone tell easy method to trigger only one instance for the same request?(I do not want to open each instance and see and then run. It will take time) Thanks Faisal

Hello.  I have a question regarding process models when setting scheduling to repeat a node daily. If the scheduler is set to repeat daily on weekdays, does this take into account holidays we have inputted into our calendar as well? I could not find documentation going into it. Image below. For context I want to have an email sent every nonholiday week day for 14 days.

Hi All,         At What Scenario will use Activity Chaining and Swimlane?  Thanks in Advance!

Hi All, can use MNI configuration for start process smart service. As we have an advantage of process will start different or same engine  based on the load and memory consumption will not be much . Bcoz, we have design where we need start more than 1000 process instances ?  will it allow iterate more than 1000 atleast incase of start process smart service -since memory issue will handled by loading into different engine?

I am trying to export data from an editable grid in an interface to a PDF file. The only problem is that the data that I have managed to get exported does not appear displayed with each field being displayed in different rows as it was supposed to. It is displaying as showed below: I have tried using "char(10)" in between lines but it has not worked. Below, an example of the code that I have implemented in order to do so: Could you please help me understanding how to get something like this: N; N; N; (...) instead of something like this: N; N; N; (...)??? Thank you for your attention.

Hi All, Could you pls any one explain MNI and when do we use MNI ....what is the Purpose of MNI Thanks in Advance!

I am new to Appian and I am evaluating this platform recently.  I defined a workflow without "process start form" it worked as expected and data finally has been save into db; This is my workflow and it is as simple as enough: And then I tried to add a "process start form" (I didn't want it but seems a "start form" is required if you want to start a process from the site pages), in my "process start form", there is nothing but a "Notice" text block and a "Submit" button(submit = true). but it behaved oddly since then. It showed that it only has "Start Node" and "End Node" now when I debugged it.  From the debug monitoring tab it seems totally not my workflow. Please can anyone tell me what's wrong?

I have two user Input Forms(A,B) in Process Model. Form- A Enter Data, Form-B review  the data and view the uploaded files using the StartProcesLink(). When i clicks the StartProcessLink() it opens another interface with read-only. When i complete the StartProcessLink() form it navigating back to Form-A instead of Form-B? Noticed backend when it completes the StartProcessLink() Process instance,   Creating new instance with parent process and Old parent instance still Active. Any inputs or is this limitation?

I have a connected system that needs to be manually clicked in order for it to get a token. Once you press the "Authorize" button, it somehow saves the token in Appian and then you can call an integration. Can that same functionality be replicated in a Process Model? What needs to happen for the integration to get that token in the PM? Or is there a way to get the token in a PM?
