Wage Type Delimitation for Change Validation 
Use
The Delimit function refers to a single wage type. A wage type table is delimited on the wage type level and must be carried out for each wage type individually.
Alternatively, you can use the Delimit function following the instructions under
Delimiting Objects.Constraints
If you use the Delimit function for wage types, you should note that a wage type is delimited irrespective of the wage type options for retroactive accounting (R1 to R4).
