Parameter has no data type- error in service binding for custom entity

I am getting error: Parameter LTID has no data type.

Custom entity:

[Andre_Fischer]

have you tried to use a data element instead of a built in type ?

[Ranjan__Panda]

Example to use instead of abap.char(4) or abap.dats . Use char4, datum or relevant data element.

Thanks Andre. Yes its working with data element. But why does not accept normal data types and it accepts data element?

Hi! Have you found a way to use normal data types? I'm facing the exact same problem here
