&
The Essbase Report Writer & command prefaces a substitution variable in the report script.
Syntax
& variableNameNotes
Any string that begins with a leading & is treated as a substitution variable; Essbase replaces these variables with their associated values prior to the parsing of the report script. Member names beginning with & are considered substitution variables by Report Writer.
Example
<ICHILDREN &CurQtrbecomes
<ICHILDREN Qtr1if the substitution variable CurQtr has the value name "Qtr1".
