Update a record in D365FO with Logic apps

 I am new to F&O Integrations so as Logic apps. I was trying few basic examples with Logic apps to Insert/Update records into D365FO and triggering Logic Apps using Postman. 

I was facing some issues while updating records in D365FO through Logic apps.

Error I was getting is related to -  update blocked by Mandatory Field

  "status": 403,

  "message": "An error has occurred.  update not allowed for field 'ProductNumber'

Was not able to avoid not giving mandatory fields (tried with giving ProductNumber value, " ", 0, fx(null)).

Added screenshot for reference.

Solution/Workaround:

Use HTTP action Patch method instead of Finance and Operations - Update Record

Let us know if it worked. Help others :)
