layout controller

Java class that determines the number and position of controls on a page.

layout profile

layout set

Comprises various groups of settings that influence the appearance of the Knowledge Management (KM) user interface. It contains a layout controller, a command group for the details dialog box, and settings for collection renderers and resource renderers. A layout set can be used in a layout profile or in an iView, for example.

Lean Sigma

Lean Sigma is a blend of two methodologies. In general, the lean approach focuses on eliminating all types of waste, including overproduction, waiting time, transportation, processing, inventory, motion, and scrap. (See Six Sigma.)


See Lightweight Directory Access Protocol.

Life and Work Events Builder

Administration tool for creating and editing Life and Work Events in the SAP Enterprise Portal.

Life and Work Events runtime

iView that displays Life and Work Events as task lists for users in the Enterprise Portal.

Lightweight Directory Access Protocol (LDAP)

LDAP is a networking protocol for querying and modifying directory services running over TCP/IP. A directory is a set of information with similar attributes organized in a logical and hierarchical manner.

linguistic search

Search mode that, by using word stemming and linguistic analysis, retrieves documents containing linguistic variants of a search term (for example, "mice" and "mouse".

linguistic search

A search method that finds linguistic variants of search terms as well as exact instances. For example, if you search for "mouse" this search method also finds "mice"


A connection to a document or document-like object. The link name can be different from the name of the document. If a link points to a document that is versioned (see versioned folder), it points to the most recent version by default.

linked server selector

Drop-down selection list appearing in the Query Editor UI for choosing a specific database (represented by the Microsoft SQL Server linked server). The linked server name is a required parameter for direct access, and the selection of a linked server initiates direct access.

Link Load Balancing

Link load balancing technologies can be applied to manage traffic for a data center across multiple links to the Internet, choosing the optimal link for transmitting data to a given location based on performance.

List form

A template made available by the Unification Server by means of which the Database Unifier displays the record set retrieved by a user query in tabular form. The query may be launched by clicking a link or by a Drag and Relate action.

list-edit XSL

XSL stylesheet used by the form-based publishing application for presenting multiple documents in an HTML form that enables users to select and edit individual documents.

list-view XSL

XSL stylesheet used by the form-based publishing application for displaying multiple documents in an HTML form.

Local Persistent Object Reference (LPOR)

LPOR is used anytime workflow needs to implicitly instantiate the ABAP class, for example, when raising an event.


The lock mechanism prevents a user from deleting an iView from a page.

lock server

A backend machine in a clustered portal environment that accesses the persistence layer for all the portals in the cluster. The persistence layer includes the Portal Content Directory (PCD), user management, system databases.


A logger is a virtual entity used to control how messages generated by a Java package in the mySAP Enterprise Portal are logged. Packages are assigned to a logger. In turn, one or more logger classes can be assigned to each logger and each logger class writes to a different log file.

logger class

Defines the output format of logging information in the Enterprise Portal. For example, the logger class SimpleFileLogger writes logging information in text format to a file. One or more logger classes are assigned to a logger.

logger pattern

Describes which information and in which format logging information is to be written to log files. You can set the logger pattern in the Logging Console or in the logging configuration files on the Java iView Runtime.

logging level

Level at which logging information is written to a log file or screen. For example, if the logging level is set to INFO, all information messages, warning messages and severe messages are written to the log file or screen, whereas if the logging level is set to SEVERE, only severe messages are written.

logon ticket

A logon ticket is a piece of information used for user authentication and Single Sign-On with SAP Systems. It is issued to a user when he or she logs on to an SAP System that is configured to create tickets (for example, the SAP Web Application Server or the mySAP Workplace). The logon ticket is only issued after the user has been authenticated, for example, using user ID and password.
