Replace multiple values with a single value (constant or calculated).

Use cases

• Creating flags that can later be used in expressions. In this case the flag will designate a group (set), therefore verifying if a value belongs to the group can be done by checking the flag. For instance, instead of expressions with multiple comparisons, e.g.

  if([x]='A' or [x]='B' or [x]='C' ...) 

  it can be more convenient to flag A, B, C,.. with 'Yes' and then rewrite expressions using the flag:

  if([Flag]='Yes', ...) 

• Group values for charts (e.g. changing insignificant dimension values to "Other")
• Calculating new values of a column only for particular values in another column, leaving the rest unchanged.
