You can link the Warehouse Management system (LE-WM) to various external systems, such as warehouse control units (WCU) or fork-lift systems. The ALE interface is available for communication with these systems. Its functionality is embedded in LE-WM.
The following functions are supported through this interface:

Link SAP System to an external system
  • Send transfer orders

  • Release reference number

  • Send cancellation request for transfer orders

  • Send system inventory records

Link external system to SAP System
  • Report transfer orders (storage bins determined by external system)

  • Report "Cancellation of transfer order"

  • Move storage unit

  • Create/cancel transfer requirements

  • Verify inventory count data

  • Block storage bins

  • Send general information text

The data is transmitted in the form of intermediate documents (IDOCs). In the Warehouse Management system, the transmission data is set up in the form of IDOCs, the external system is determined, and the ALE interface is called up so that the data can be sent to the system found.

This link is based on an asynchronous Remote Function Call (aRFC). The data is placed into intermediate storage when it is passed from LE-WM to the external system, or it is sent directly to the partner system, or transmitted as soon as a certain buffer size has been reached. On the receiving side of the external system the data must be received by a Remote Function Call. The external system is responsible for receiving and sending the received data.

When the data is sent from the external system to LE-WM, the external system is responsible for sending the data (queue technique) and for placing the data into intermediate storage. Here, too, the data is transmitted via Remote Function Call.

  1. Install the required basis components for the interfaces ALE and RFC.
  2. Warehouse view
  3. Communication

In the following section, the required activities for setting up the communication are listed in detail:

  1. Warehouse view
  2. Communication

If the standard interface has been modified, that is, you are using your own message types, your own processing function modules or your own standard tasks for error recovery, you must take these changed into account in the ALE interface. For more information on this subject, refer to the Implementation Guide Distribution (ALE). In particular, refer to the section on User Exits / Developments in the Implementation Guide.

The SAP system communicates with the external systems via the standard interface aRFC. For information regarding which computer types this interface can be used with and how the communication takes place from a technical point of view, refer to the SAP information brochures.

Refer also to the documentation of the communication interface and the general documentation on the ALE interface.
