How Up to Date Are Your SAP Standard Payroll and Time Management Schemas?

Ensure that your standard schemas are up to date and avoid the risk of missing important SAP updates in your modified schemas.
Key Concept

Standard SAP Releases 4.6C through SAP ERP Central Component provide Payroll and Time Management schemas, which customers either copy to their own versions (local clients) for further modifications or call from their schemas. Most payroll experts use these standard schemas as a point of reference within their system.

Do you make changes to an SAP standard schema in your development client? For example, you might apply an SAP Note fix or add documentation to a schema call or function. If the answer to this question is yes, then your SAP standard schemas may not be as up to date as you imagine.

SAP standard schemas are stored in client-independent table T52C0. However, if any edits are made, they are stored in client-dependent table T52C1, therefore creating a local copy of the schema. All updates applied to the standard schema in client 000 are not reflected in the modified schema in your local client (client 100).

Most companies believe their SAP standard schemas are up to date because they apply HR Support Packages (SPs) in a timely fashion. This is not necessarily the case. Use the following best practices to determine how up to date your SAP standard schemas for Payroll and Time Management really are and how to resolve discrepancies:

1. Understand what happens when you amend a schema in a development client

2. Recognize if changes have been made to your productive client

3. Learn how to revert your schemas back to the SAP standard
