When using a flow in powerapps to update a page in NAV it says:
"status": 400, "message": "Invalid Mashup Expression using supplied values.\r\n inner exception: The value is not updatable.", "source": "127.0.0.1"
Do you update item in Dynamics NAV using a flow looks like below? Could you show me how is your flow configured?
Could you try the action “Dynamics NAV-Create item” to see if it works and back to me the result?
I have seen a similar error on another thread with Dynamics Financials, record creation of Dynamics Financials is currently not supported, I am not sure if the similar error is caused by the same reason. Please check the thread for a reference:
Thanks for your reply. Could you show me a screenshot of your flow configuration with the action "Update item"? Please also provide your Flow id.
I am trying to involve someone who are familiar with this issue to take a further investigation on it.
I haven't got an update item flow yet. I thought that create item would be easier to make, and when the create item is working I wanted to look into updating.
edit: Maybe the title was a bit misleading. I never had an update flow, with updating I ment creating.
I have some updates for you. The NAV connector is ready only at this time so you will not be able to call back and create or update records. So you are getting the error message with the action “Dynamics NAV>Create item”.
PGs are working on write back now, I don’t have a timeline on this issue. Once I got a timeline, I will back to you.
