Consuming Web Service in C# application (SAP)

This error occurs when remote server doesn't provide a response to your request and connection is broken before request is complete. To fix this issue, first setup a request that includes QaaWsHeader and ReportBlock configuration, then create the Request and in last using ServicesSoapClient, you can make method to send results.

Understanding SAP Web Service Components

When consuming SAP web services in C#, you need to configure three main components ?

• QaaWSHeader ? Contains authentication and session information
• GetReportBlock ? Defines the data retrieval parameters
• ServicesSoapClient ? Handles the actual web service communication

Example

Check out the below code and it may help ?

Sellers.QaaWSHeader qaawsHeaderDatos = new Sellers.QaaWSHeader();

Sellers.GetReportBlock_WBS_Sellers getReportBlock = new Sellers.GetReportBlock_WBS_Sellers();

getReportBlock.login = userWS;
getReportBlock.password = passWS;
getReportBlock.refresh = true;
getReportBlock.startRow = 0;
getReportBlock.startRowSpecified = true;
getReportBlock.endRow = 1000;
getReportBlock.endRowSpecified = true;

Sellers.GetReportBlock_WBS_Sellers_Request WSRequest = new Sellers.GetReportBlock_WBS_Sellers_Request(qaawsHeaderDatos, getReportBlock);

Sellers.BIServicesSoap BiService = new Sellers.BIServicesSoapClient();

Sellers.GetReportBlock_WBS_Sellers_Response FinalResponse = BiService.GetReportBlock_WBS_Sellers(WSRequest);

object[][] yourTable = FinalResponse.table;

Code Explanation

The code creates a QaaWSHeader object for authentication, configures the report block with login credentials and row limits (0-1000), then sends the request through the SOAP client. The response contains a two-dimensional object array with the retrieved data from the SAP system.

Conclusion

By properly configuring the QaaWSHeader, ReportBlock parameters, and using ServicesSoapClient, you can successfully consume SAP web services and handle connection timeout errors in your C# applications.
