It is possible that you might be missing a group if you have nested groupings (parent/child groupings) since you mentioned that you have a drilldown report. &nbsp;<br />
For example if you have four groups nested in hierarchical fashion (e.g. &nbsp;Group1 -&gt; Group2 -&gt; Group3 -&gt; Group4) and by chance your columns only accommodate three groups (e.g. Group1 -&gt; Group2 -&gt; Group4) for example, then the values would be different and your result would not calculate correctly.<br />
<br />
<br />
Also, based on your Excel Spreadsheet, you need to provide a condition in your expression (e.g. using IIF) to determine if the values in the row are ELA or MHG in order to calculate the correct ratio for each row. &nbsp;It looks like your aggregate functions is aggregating for both ELA and MHG.

I have a drilldown report and Group results for ELA/MHG are not calculating RATIO separately....  Any idea what I am doing wrong?

Ratio=Sum(Fields!ccSTA_MED.Value, "ReportDB")/(Sum(Fields!ccSTA_MED.Value, "ReportDB")+Sum(Fields!ccSTA_TELE.Value, "ReportDB")+Sum(Fields!ccSTA_ICU.Value, "ReportDB"))

SSRS - Ratio not calculating correctly

SQL Server Reporting Services (SSRS) is a server-based report generation software system from Microsoft. It can prepare and deliver a variety of interactive and printed reports and is administered via a web interface or its web service. Its web services interface also supports the development of custom reporting applications. Finally, SSRS can also be integrated with SharePoint. SSRS competes with other business intelligence tools, most prominently Crystal Reports.

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server 2005 is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning. It includes support for managing XML data and allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests.
