Hi @Kalaisri_K

DataTable.Merge returns "Expression does not produce a value" Error

Hello Browsing through the forums I encountered this error a fair few times, but none of the solutions seem to work in case of merging Data.Tables. When I try to use the ‘Invoke Method’ activity I get the following error: “‘DataTable’ does not have a public instance method named ‘Merge’ matching the parameter types, generic type arguments, and generic type constraints supplied to InvokeMethod ‘Invoke Method’.” This is what it looks like in UiPath [image] Thanks for your time.

You should add the respective parameter in the properties panel of the invoke method activity. In Your case data table should be added to parameter property.

Please refer to the above link

Thanks,

Hi,

Ideally you should use the ‘Merge Data Tables’ activity which is designed to help you exactly with this!

Best of luck
