Problems Calculating Data
The topics in this section document problems you may
encounter when calculating or summarizing data.
- Unexpected Summary Values in Nested Sets
If a report contains nested sets, summaries other than the inner set summaries may contain unexpected values. For example, you insert a summary in a crosstab that contains a set with years in the rows. - Null Results for Calculations Using SAP BW Data Sources
When using a SAP BW data source, the expression you use in your calculation is evaluated as a null value if your expression contains a null item. For example, in the calculation some_expression = result, the result is null if a row or column that the expression references includes a null value. - Incorrect Results with IBM Cognos PowerCubes and Time Measures
If a report uses an IBM® Cognos® PowerCube data source and a combination of data items, you will encounter incorrect results. - Incorrect Results in Summaries When Using OLAP Data Sources
When using an OLAP data source, summaries that use for clauses give incorrect results.
