Create web service for /POSDW/CREATE_TRANSACTIONS_EXT

Hello Experts,

In our POSDM implementation, we are trying to connect third party POS to POSDM via custom Middleware (.net application). I am trying to create a webservice for /POSDW/CREATE_TRANSACTIONS_EXT function module so that via middleware we can upload the T-log into POSDM.

While creating a web service we are getting an error "

SOAP application

"urn:sap-com:soap:runtime:application:rfc:710"

does not exist"

I have also checked the function module is RFC enabled. If anybody can put some light on how to solve this problem would be really appreciated.

Thanks

Mayank
