Environment Variable for calculated field

Posted on 1 Oct 2024 09:15:33 by SteRe 254
Hi all, 
I would like to create a new field to my table with dynamic value. 
The value would be a link which is to be built from a base URL + dynamics parameters given by specific fields at the current record. 
Rigth now I have a new field type formula using concatenate function to combine a static base url and values of relevant fields. So far so good. 
But I would like to make this base URL part also dynamic as my Dev system should link the dev instance of the linked page, test to test and production to production. 
So my idea was to create an environment variable to store the base URL, but I did not found the right way to get the current value of this variable into my formula. 
 
Would be happy to get any guide. Thank you!

    My code would be used in a Flow (Power Automate). If you wanted an environment variable in PowerApps, then just store the value in a list, and use the Lookup() function to get and set it.

    Environment Variable for calculated field
    Hi all, 
    I want wo provide some update in here. 
    It turned out my initial request can not be fulfilled by the system - there is no option to directly request value of an environment variable within the new field typ formula so far. 
    I understood there are workarounds using workflows or cloud flows to update the value. Works, but in this case I don't need the calculated formula field. I can simply use a string field and set it value with a cloud flow based on chages in other fields. 
     
    I figured out another alternative for my use case. As I would like to like another company-internal website I can also embedd this as an iframe to my form. In this case I need to inject the iframe URL running a little JS. So I have two options now how to solve my problem (POC for both working) and I can check with the users which alternative they prefer from a UX perspective. 
     
    Thanks for your support.

    Hi
     
    Once you add the environment variable and you publish it, and you refresh your flow (just reload it), you will be able to add the Environment Variable.
     
    Then when you publish all customizations and you export it as managed, and import it into the next environment, you will update the value on import.
     
    So I dont know why you are having an issue, as you didn't share anything, but what i said and what you did is correct.

    @abc_123 do you refer to a direct use in the formula field or a power automate flow to be built to get the value?

    The syntax for an environment variable is:
           @{parameters('displayname (new_displayname)')}
     
    You could create a new variable, and then populate it with the environment variable and the "relevant fields".
     
    This is in an Automatic Flow, putting the environment variable, the ID, and a field called AmountConsumed together
    @{parameters('envMyVal (new_envMyVal)')}-@{triggerOutputs()?['body/ID']}-@{triggerOutputs()?['body/AmountConsumed']}

    do it with a classic workflow or a power automate or an async plugin.
