**
Personnel calculation rule** XALP is used to process
wage type /001 (valuation basis 1).

1. Personnel calculation rule XALP
ensures that an employee is not paid less than his/her basic salary
for any work carried out on the basis of a different payment.

A comparison with the employee's basic salary (master valuation basis) is used to determine whether the value of the valuation basis for the different payment (valuation basis with ALP split) is greater than or less than the value of the master valuation basis.

If the value of the master valuation basis is greater than the value calculated for the different payment, then the value of the master valuation is used as a basis for further accounting.

If the value of the master valuation basis is less than the value calculated for the different payment, then the value of the valuation basis with ALP split is used as a basis for further accounting.

2. With the help of personnel
calculation rule XALP, processing is effected for a premium and the
extra pay indicator, if it is specified for a different
payment.

Three steps are processed for personnel calculation rule XALP:

1. In the first step, wage types /001
(valuation basis 1) are generated in table IT for the basic salary
and for the records with a different payment (valuation basis with
ALP split).

2. In a second step, the valuation
basis with ALP split is compared with the master valuation basis,
and the results are valuated.

The system determines whether a premium has also been specified for the different payment. Personnel calculation rule XALQ is accessed for this purpose and then reads table T510P (premiums). The resulting values are processed in the personnel calculation rule.

3. Finally, function
*ZLIT* summarizes the entries in table ZL
and their corresponding wage types and writes them to table
IT.

**Example**

1. Calculate a higher valuation
basis

An employee works for one day in another position which is recorded via the window*Different Payment* in
infotype 2003 **Substitutions**.

The employee's normal hourly wage is $12 an hour. However, the other position is only paid at the rate of $10.50 an hour. To ensure that the employee does not lose money because of this work center substitution, personnel calculation rule XALP is used to ensure that the employee's normal salary is used as the basis of the calculation.

2. Premiums

In the standard SAP R/3 System, calculated premiums are written directly to valuation basis /001.

In personnel calculation rule XALQ, however, you can also specify rules to determine, for example, that a premium must not be greater than 10% of the master valuation basis.

**Requirements**

1. Wage type /001 (valuation basis 1)
must be set up.

2. The premiums must be maintained.
For more information on this, please refer to the sections
**"Group personnel areas
for premiums"** and
**"Determine
premiums"**.

3. Before you modify personnel
calculation rules, you must have a sound knowledge of how personnel
calculation schemas, personnel calculation rules, functions and
operations are used.

**Standard settings**

The personnel calculation rules mentioned above are part of standard calculation schema XT00

**Recommendation**

Initially, you should use the settings in the standard SAP System. If you want to make changes, you should use the existing personnel calculation rules as a model.

**Activities**

1. Check that personnel calculation
rules XALP and XALQ meet your requirements

2. If necessary, adapt personnel
calculation rules XALP and XALQ so that they meet your
requirements
