Changing a datatype for a column in an odata datasource

Hi,

I'm trying to import an odata datastream via an OData Source component. The datastream contains a column with decimals in it (like 0.42). The OData Source component defines this column as a DT_NUMERIC with precision 38 and scale 0. 

For some reason the decimal part of the number is cut off during the import. I have tried a derived column with a type cast to decimal(38,2) and a data conversion.

I also tried changing the data type at the most logical place for me: right at the source in the OData Source Component with the external columns but SSIS displays an error "Property value is not valid" and then starts telling me "

Error at Retrieve Werkorders [TDO Werkorders [246]]: The data type of output columns on the TDO Werkorders cannot be changed, except for DT_WSTR and DT_NTEXT columns.

Error at Retrieve Werkorders [TDO Werkorders [246]]: System.Runtime.InteropServices.COMException (0xC020837D)
   at Microsoft.SqlServer.IntegrationServices.OData.ODataSource.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
   at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostSetOutputColumnDataTypeProperties(IDTSManagedComponentWrapper100 wrapper, Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)"

I have been looking at this for over a day now. Does anyone have a clue?

Thanks in advance. Regards,
