You use the Last Refresh Date cell from the Templates in the Report Manager on your report page. You then reformat the cell as Tuesday, January 22, 2012. What is the result when you edit the…

When you directly edit the formula using the Formula toolbar to concatenate a string literal with the LastExecutionDate() function, the explicit formula takes precedence over the custom date format applied to the cell. The date value returned by LastExecutionDate() is implicitly converted to a string in its default short date format (1/22/12), discarding the 'Tuesday, January 22, 2012' formatting that was set on the cell.

A 'Computation Error' is triggered by invalid mathematical operations or unresolvable calculations, not by string concatenation with a date function, which is a supported operation.

An 'Incompatible Data Types' error occurs when types cannot be reconciled at all, but Web Intelligence performs implicit type conversion when concatenating a string with the output of a date function.

Web Intelligence does not wrap date values in double curly braces when rendering concatenated formula output; the date is converted to its default short string representation instead.
