calling SAP function directly within power app

(1) ShareShare
ReportReport
Posted on by 304
Hi,
I'm currently trying to recieve data from our SAP system via a function to display this data in a gallery inside the app.
I already succeeded with building a flow that calls this function and returns the result to the app, which works fine. But is there a way to do so directly inside the app, without using a flow?
 
I found the SAPERP connector and the SAPERP.CallRfcJson function, but I can't get it to accept my parameters. More precisely, it's about the "rfc inputs" parameter. Since the function doesn't expect any input, how can I avoid this parameter? It seems like it's required (if I understand the error message correctly). Below I will put in a screenshot of my code and the error:
 
 
 
 
 
Could somebody please provide me with assistance?

    Hi @LisKr
     
    Please make sure to share the documentation and a screen shot of what you are referring too, so we can find it faster. Are you using V2 or V3? And where did you get the JSON you expected it to use? I see one of them there, but its not what you would use.

    Did you tried passing the values to the power automate ?
     
    • Pass the necessary values to power automate.
    • In Power Automate get the variables value
    • Call the SAP ERP function and check .
