Fiori - BAPI Return Message in oData Service

Dear All Gurus,

I have created a Gateway Service (For a Custom App) to create Purchase Order (ERP) Using BOR object "PurchaseOrder.CreateFromData1".

When I execute the program in GW Client , Im getting below output (please find attached txt document for the full output). I understand that this is ann error throwing from BAPI and I guess this is from the BAPI Return structure and feel like the complete message is not showing but only the 1st line of Return message. Due to this I am not able to identify what data is missing and where is the cause of this error ...

Plz advice how to get the full message
