Table as input for SAP Netweaver Gateway service

Hi All ,

          I am using SAP Netweaver gateway 7.3 and trying to create Service using Remote FM.

         we have requirement to fetch data based on multiple selection of week, for that we need to keep Table as input parameter in FM.

         But when i am creating Service using import command in SEGW. it is not working.

          if any one has done table as input parameter in Gateway , kindly let me know the process.

        Thanks in advance.

Regards
