You can specify the name of the form routine that is called when the system runs the function or operation. This form routine usually has the name FU<Function name> or OP<Operation name> (for example FUWPBP for the function WPBP). If you select the user-defined field, you can enter a name that differs from this convention.

You can use the country assignment to specify the country version for which the function or operation should be available. This assignment is also transferred to the function or operation parameters. For example, when you delete a country version from the country assignment, this country version is automatically deleted in the country assignment of all parameter values.

The Parameter list allows you to maintain parameters and their characteristics. There is information about the use of the parameters' structure in the documentation about each function or operation.

You can enter fixed values for parameters with type blank. You can display or change the possible fixed values by selecting the parameter and choosing <Detail>. In the Value for Parameters dialog box you can see the values that are valid for this parameter, and their meaning. For each individual parameter value you can display the country versions in which this parameter is valid by choosing Select.

You can use infotypes in the standard function bar to display the infotypes that a function uses. The system uses this information to generate the personnel calculation rules. If the function OPT is available with parameter INFT in the personnel calculation schema, the system only reads those infotypes that are required in this personnel calculation schema. You can enter your own infotypes here.

You can display tables in the payroll log over the input and output parameters in the standard function bar. In the payroll log the system shows the tables entered for each function, separated according to input and output.

The model determines how the syntax of an operation is structured. The individual points of the syntax can have different meanings depending on the model. Using the model you can specify the length of the operation name and the length of different parameters. There are numerous models available in the standard system which you can use to create your own operation.

When you create a new operation the system automatically generates a standard check routine that checks whether the specified parameter model and the parameter values entered are correct.

However, the system does not check whether the combination of the individual parameter values is correct.

You need a customer-specific check routine for this which is called instead of the standard check routine. The switch Customer-specific check routine indicates that such a specific check routine exists for this operation.

For the individual parameters of an operation, you can display or change the country versions in which this parameter is valid. To do this, select a parameter and choose Select <Detail>; Detail.. The country versions valid for this parameter are displayed in the Valid Countries for Parameter <Parameter> dialog box.
