Introduction to Rules 

A rule is a Boolean expression that you can use in a prerequisite statement, in a check, or in another rule. Rules enable you to refer to frequently used Boolean statements simply by specifying the rule name.

RULE1 AND COBL-BLART <> 'SB'

In this example, the rule is named RULE1. When the system processes this statement, it first processes RULE1 and then checks whether the document type is SB.

To create a rule:

  1. Enter a rule name.

    2. The rule name can be a maximum of 11 characters long.

  2. Create a statement in accordance with the rules described in Creating Boolean Statements for the FI-SL System.

    3. Starting with Release 4.0A you can enter a rule statement either directly or using the Formula Builder.

    If you enter the statement with the Formula Builder, the system uses the new syntax rules for Release 4.0A. For more information, see Syntax Rules for Boolean Statements and Formula Builder.

    If you enter the statement directly, you must use the old syntax rules valid in Release 3.0 or 3.1. For more information, see Old Syntax Rules for Boolean Statements.

  3. Enter the name of the rule in another statement.

You can use rules in:

For more information on using rules in ledger selection, see FI-SL Master Data: Special Purpose Ledgers.

For more information on using rules with rollups, see Creating a Rollup.

For more information on using rules with the Report Writer, see Defining Selection Criteria.

When you use rules in validations and substitutions, the rule must belong to the same Boolean class as the validation or substitution you are creating. For more information on Boolean classes, see Boolean Classes.
