Hi experts, 

making post to https://myXXXXX.s4hana.ondemand.com:443/sap/opu/odata/sap/API_SALES_ORDER_SRV/A_SalesOrder

We need to create lots of sales order line items and when reach aprox 400 line items, we get this message error. It seems a "timeout" , but don´t know why.

Could not get any response

This seems to be like an error connecting to https://myXXXXX.s4hana.ondemand.com:443/sap/opu/odata/sap/API_SALES_ORDER_SRV/A_SalesOrder. The response status was 0.

If I create less line items ( for example 350 ) , we get no error and sales order is created.

Thanks for any help or suggestion .
