Error: Requested index value not covered by interface configuration

Hi Experts,

I am getting below error when executing end to end. It is working fine if i executed in Operation Mapping.

my scenario is multi mapping + additional java mapping in SAP PO 7.4.

"Transmitting the message to endpoint <local> using connection AFW failed, due to: com.sap.aii.af.service.mapping.MappingException: Requested index value not covered by interface configuration"

Kindly help me in resolving this issue.

Regards,

Sateesh.
