Modify Record Dynamics NAV OData Datasource

[SteveApps]

Hello,

my app is showing Sales Orders and Sales Lines. On the SalesLines Gallery i can press a button which switches me on the form, where i can edit the selected entry. But when i submit the changes, it says: Invalid Mashup Expression using supplied values. inner exception: The value is not updatable.

before i tried Dynamics NAV as datasource, i have tried Excel and it worked with it.

Could it be that powerapps can only read data using a Dynamics NAV Odata Source?

Thanks in Advance

Hi SteveApps,

The NAV connector is ready only at this time so you will not be able to call back and create or update records.

Here is a thread from Flow Forum which is related to Dynamics NAV, please check this for a reference:

And now I haven’t got any updates on this issue, I will back once I got any updates.

Best regards,
