Answer 1

MULTI: Multiply
   Object
     Operation
   Use
     This operation multiplies two fields of the current entry of table OT
     and stores the result in a third field.
   Input
     The operation processed the following wage type fields:
     o   NUM (Number)
     o   RTE (Rate)
     o   AMT (Amount)
   Syntax
     OOOOO xyz
     OOOOO       MULTI       Operation name
     x                       first  factor
     y                       second factor
     z                       product
     For x, y, and z you can use the following parameters:
     o   N for the Number field (see operation NUM)
     o   R for the Rate field (see operation RTE)
   o   A for the Amount field (see operation AMT)
Processing
   In theory each field can by multiplied with any field. However, not all
   the possible multiplications are useful.
   For example, you can multiply the Amount field by the Rate field.
   However, both fields are linked to the payroll currency, for example
   10000 ESP and 5000 ESP/h. The result in this case is ESP squared/h. This
   value cannot be mapped usefully in any of the fields Amount , Rate or
   Number.
   This peculiarity should be taken into account particularly for
   currencies with more or fewer than 2 decimal places. The number field is
   interpreted differently from the fields amount and rate, which are
   always seen together with the payroll currency. Currencies, that have
   more or fewer than two decimal places cannot be stored directly in the
   number field.
