We are deploying BIP reports to SaaS instance using uploadObject method of SOAP API, But description is not migrated to target instance even though we pass it in zippeddata input parameter to SOAP request. So to add description to the report after deployment, we are invoking updateReportDefinition SOAP API method passing only report name and description, but with this description is updated and existing layout is getting deleted. Please advise on if there is any parameter we need to pass to update description alone or any other API is available to achieve this functionality.
