Custom read failed: Unknown error QlikviewSAP olapconnector

Hello Everyone,

I am using SAP olap connector to pull the data from SAP BI. Whenever i pull more records(millions of rows) to store in qvd, i am getting this error  "Custom read failed: Unknown error". But i am able to pull less data without any issue.

I try to implement the solutions mentioned in the forum like increasing timeoutfetch, using sleep etc., but it doesnt help.
