What does operation MULTI RAA do?

Operation MULTI RAA is used to multiply the value of the rate field by the value of the amount field and store the result in the amount field. This operation is useful for calculating the total amount of a wage type based on its rate and quantity. For example, if the wage type is hourly pay, the rate field contains the hourly rate and the amount field contains the number of hours worked. By using MULTI RAA, the amount field will be updated with the total pay for that wage type. References = SAP Help Portal: MULTI RAA
