Hi Vilmos,
I am facing a report related issue. while opening purchase order confirmation report, i am getting below error.
The message with Action 'schemas.microsoft.com/.../GetPartitionKey&; cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
I followed the blog mentioned below but couldn't help me.
Did you face any such issue? There wasn't any customization on that report.
