Passing Parameters with OpenDocument in SAP Design Studio navigation to Webi

Hello All,

We're passing parameters/Prompts from design studio to Webi report, In On-click event of design studio we need to pass the Null values from one of the field ,we have set of value around 10 and Null value is one of them , and We're following as below - but it is not working as expected , null value been ignored from the Webi Report.

APPLICATION.openNewWindow("BOE/OpenDocument/opendoc/openDocument.jsp?iDocID=xxxxsIDType=CUID&sType=wid&sReportName=Report Detail&sRefresh=Y&lsMpmfild1=&lsMpmfldxxx=&lsMpmField3=abc;xyz,pqr; ; &lsMpmPriority=");

is there way to pass the null value into the prompts in Webi report.

please advise on this.

Thanks in advance.
