Passing internal tables as import and export varaibles

Hi All,

I have a Function module which has 4 import parameters and one return table parameter.. when I tried to create odata service for this RFC, I see that 2 individual entity types are being created.. where as I dont want them to appear as 2 entities.. it should exactly emulate the RFC as taking 4 import and 1 return table type, so how can I achieve this.

Best Regards

Manoj
