SAP B1iSN UDT to UDT

Dear Expert,

I am stuck up on one scenario for SAP B1iSN UDT to UDT.

I got the following error.

"Exception : com.sap.smb.sbo.wrapper.com.ComFailException: Invoke of: GetGeneralService Source: SAPbobsCOM.CompaniesService.88.0 Description: Service Not Found"

Thanks & Regards,

Tushar
