SAP Logistics Information System (LIS) is a set of flexible tools for collecting, aggregating and calculating data from the operative applications. In addition to this, the data can be used as the basis for planning. Hence, information systems can be used for controlling, monitoring and planning purposes. SAP Logistics Information System is part of the overall information system in the organization and corresponds to the logistics part of the SAP system.

Structure of SAP Logistics Information System
SAP Logistics Information System consists of the following levels:
- OLTP (Online Transaction Processing)
- Logistics Data Warehouse
- OLAP (Online Analytical Processing)
OLTP (Online Transaction Processing) level consists of the different operative applications like Sales, Finance, Materials Management. This is the online transaction processing level. In this level, the system responds immediately to the user requests. The processing speed in OLTP is normally very fast. The data in concern is generally current data which is processed at this OLTP level. OLTP consists of the original source of data and used to run basic business tasks.
Logistics Data Warehouse
Logistics Data Warehouse lies above the OLTP level. Whenever a transaction is performed on the OLTP level in Sales, Finance or any other operative level, reduction in the data volume happens which is further reduced to statistically relevant parts. This data is supplied to and aggregated in the Logistics Data Warehouse.
OLAP is also called as Online Analytical Processing. OLAP is used to process historical data. In this level, reporting tools for data evaluation are present. This is used for planning and problem solving. Some of the reporting tools include the following:
- Standard analysis
- Flexible analysis
- Early warning system
