Prompt issue with Web Service

Hi All,

I have done the following steps to create webi report using web service as source.

  1. Created webi report using bex query as source with mandatory prompt as "Fiscal Year" and saved the report as "Source_Rep"

  2. Right clicked webi table and selected "Publish as web service" and created a webi service query.

  3. Used webi service query as source in webi and saved the report as "Target_Rep"

Is there any way to  change the prompt value in "Target_Rep" to show the output based on prompt without depending on source report?

I tried to  edit Target rep and input prompt value with "Fiscal Period". But the report result is not refreshed for new prompt value and showing the same result as source report.

Thanks

Priya
