As you may know, logic apps do not have any triggers available for Dynamics365 for Operations. So we have to use recurrence trigger to read data periodically from a data entity and obviously we want to filter a query. This is pretty straightforward with string or integer fields, but not with enums. Under the hood AX enums are enumeration in OData.
For example, I have new entity “RentalInvoices” and I want to filter it by AXCRMTransferStatus field and select only “pending” records.
