How to read rules and Schemas

1. Structure of relationship in Rules and Schemas:

• a)Schemas consist of Functions and Sub-schemas
• b)Some functions have the rules attached to it as one of its parameter
• c)Rules consist of a set of operations to perform some actions
• d)Operations and Functions are the executable components

As per the diagram Set of Operations make a Rule which in turn attached to some functions and those functions embedded in Schemas or Sub-schemas (Inside the main schemas) to decide the flow of the payroll program.

Structure of a Schema:




Func: This column is used to give a function name.

Par1, Par2, Par3, Par4:

• 1. Function has maximum four parameters.
• 2. The function can have zero to four parameters as per the definition of the function.
• 3. Pressing F4 we can get the list of all the values which can be used as parameters.
• 4. For some functions in the first parameter is the name of the rule created.
• 5. These parameter values are predefined the function is being created.

D:

• 1. This column is used to comment and uncomment a function.
• 2. If (*) is being put then the line is commented and will not be executed in Payroll processing.
• 3. If nothing is given then the line would be executable.

Desc

• 1. In this column description for the function is being used.

Functions: Functions are used for;

• Performing some payroll computations (E.g. INEPF function calculates the PF amount of an employee during payroll run)
• Calling rules (E.g. P0045 function calls a rule INLN to compute the loan details of a personnel number).
• Getting data from Infotypes (E.g. P0581 will get the data from Infotype-581 for payroll processing).
• For some decisions. (E.g. IF & ENDIF function is used to execute as per the true and false decisions) etc.

Rules:

• Rules are used for holding a set of operations for a particular requirement to be accomplished.

Attributes:

• Program Class.
  • a. There are two program classes to be assigned to the rule while creating.
  • i. Payroll (C).
  • ii. Time (T).
• Country Grouping.
  • a. For Payroll program class the country grouping should be mentioned. (E.g. 40 for India).
  • b. For Time management rule the country grouping should be (*).
• Employee Sub-grouping.
  • a. All the wagetypes have an attribute of employee sub-grouping.
  • b. It varies client to client.
  • c. Value 3 means EE sub-grouping is 3.
  • d. Value * means all EE Sun-groupings.
• Wagetypes.
  • a. The wagetype in the internal table which is meant to be processed by the rule.
  • b. If a value for Wagetype is being given then the particular wagetype is being queried for processing.
  • c. If **** has been given then all the wagetypes present in the particular internal table will be processed.

Structure of the Rule.



Frequently Used Internal Tables in PY Processing:

• The Payroll driver uses lots of internal tables used for storing data temporarily in the program for processing. Some of the important internal tables are:

The structure of internal tables:



EE Sub-grouping:

1. The Wagetype is assigned to a particular Employee sub-group.
2. 3 is a particular employee subgroup for basic pay wagetype.
3. * value means for all EE sub-grouping.
