That's what I ended up doing, then on powershell I ran a script to parse and extract the constant's value and output the key value pairs to a csv file.

I do not know of a way to do this through Appian without some development but you could add them all to one app and export them which would give you the files and names with all the constants

Hi Oscar,
I don't think there is any OOB functionality to achieve this. As suggested by Jose try using custom plugin to achieve this functionality.

Thanks but they would like to avoid adding more plugins to the environments. Ideally this should be done with OOO functionality.

Hello Oscar,

Depending on which version are you, Maybe this functions can help you in your requirement

Custom Content Functions has the fn!getConstantsFromFolder: Returns constants from a folder
forum.appian.com/.../summary

Constant Utilities has the fn!getconstantobjectbyname
forum.appian.com/.../summary

Get Constant By Name has the function PCF_getConstantByName
forum.appian.com/.../summary

Hope this helps

Jose

Update: I tried exporting all of the environment's constants into a patch file, then I created a powershell script to parse the xml files and retrieve the constant's name and value then store it into a file. While this achieves the final purpose, I don't know yet if it will pass business requirements. Ideally this process should be done entirely in Appian.

Thank you for the response, I think this could work to an extent but I don't know if I'll be able to create a table for this purpose. The requirement is to export all the constants across the board not a subset.

Hi Oscarb,
Assuming that you know the constant names, then what you can do is like Create a process model to store the constant values in Process variables and then persist these details into DB.
Need to check how programatically we need the list of all constants available in Environment.
