SAP Library - IDoc Interface/ALE
IDOC consists of several segments, and segments contain several fields. IDOC contains the following three types of records One or many Data Record 3.
One or many Status record. The messages that are exchanged are in the form of IDocs or Intermediate Documents. IDocs act like a container or envelope for the application data.
Every IDoc has exactly one control record along with a number of data records and status records. If we send data to an external partner, we generally speak of EDI, while ALE is a ale idoc in sap to reliable replicate data between trusting systems to store a redundant copy of the IDoc data.
The difference is made clear, when we think of a purchase order that is sent as an IDoc. If we send the purchase order to a supplier then the supplier will store the purchase order as a sales order.
This was last published in February Related Ale idoc in sap. A server connection presents itself to the Gateway and exposes a Program Identifier.
What is the difference between ALE, EDI, IDocs and BAPI?
If the Program Identifier is found in the list of registered Program IDs, the Gateway server then offers a connection to the server, which "Accepts" a connection. Program IDs and Load Balancing If the Gateway Server has a connection to a particular server instance and another server instance presents itself to the gateway, then the gateway offers the connection and then ale idoc in sap functioning in Load Balancing mode.
Using a proprietary algorithm, the Gateway sends different messages to each server depending on demand and total processing time. This may cause unpredictable results when messages are validated by schema and application.
This mechanism is proprietary to SAP application development and might work by comparing total throughput of ale idoc in sap connection, the number of times in wait state, and so on. This means one connection ale idoc in sap receive nine messages and a second connection might receive one message.
If five of the nine messages are rejected for schema validation and the one message on the other connection is rejected for schema validation, you might suspect that you are missing SAP event handling messages.
Load balancing in server inbound to adapter from SAP situations is handled by connecting multiple instances of the adapter to the SAP system.
