Patch Types

A patch corrects errors in the R/3 System or makes necessary adjustments, for example, due to legal changes. The objects affected are replaced in your system.

Each patch is valid for only one release (but for all databases and operating systems) and has an exactly defined number of predecessors. The upgrade of the following release or correction release contains all the patches of the previous versions that were available up to the delivery of the upgrade.

SPAM ensures that patches are applied only in the order dictated by the serial number.

To avoid problems, apply every patch as soon as it is available. This keeps your system up-to-date.

• PAT

This type denotes a SPAM update. This contains improvements and extensions of the SAP Patch Manager.

• HOT

This type denotes a Hot Package. This contains a collection of correction for serious errors in Repository and Dictionary objects. The corrections are periodically assembled in Hot Packages and are announced in the OSS.

• LCP

This type denotes a Legal Change Patch (LCP). However, like a Hot Package, this contains the same collection of correction for serious errors in Repository and Dictionary objects.

It may also contain corrections and further adjustments due to legal changes for the SAP Human Resources (SAP HR) component. Unlike Hot Packages, LCPs are offered to all customers along with the SAP HR component.

• FFD

This type denotes an FCS-Final Delta Patch (FFDP). An FFDP brings an FCS system to Final State status before Hot Packages or LCPs can be applied.

• CRT

This type denotes a Conflict Resolution Transport (CRT). A CRT is exclusively used for add-ons, for example, IS-IS or IS-OIL. It resolves conflicts that can occur between a patch (Hot Package or LCP) and an add-on.

Note that a CRT that is valid for an add-on release also resolves all conflicts with earlier releases from this add-on.

SAPKI (SAP add-on)

SAPKJ (Add-on from SAP partners)

SAPKP Country adjustment

• BWP

This type denotes an SAP Business Warehouse Patch (BWP). This contains a collection of correction for the SAP Business Information Warehouse (SAP BW) component. BWPs also contain Basis corrections if they are needed. You can only apply BWPs in systems in which the (SAP BW) has been installed.
