Creating & Sending an IDoc to ERP using JCO 3.0 and IDoc Class Library 3.0

[former_member1]

This blog will help in creating an application to send the IDoc from JAVA to ERP System.

JCO 3.0 & SAP IDoc Library 3.0 provides 2 ways in which the IDoc can be sent to the ERP System

1. Sending an IDOC as IDOCDocument
   • In this the user can manually create an IDOC Document and can send it to the ERP System
2. Creating an IDOC as XML and sending as Document List
   • In this User can generate XML and then can send the XML as IDocDocumentList

Prerequisite:

• JDK/JRE 5,6,7
• sapjco3.jar
• sapidoc3.jar

sapjco3.jar & sapidoc3.jar can be downloaded from http://service.sap.com/connectors

If the version of Java 1.3 or 1.4 then user should use JCO 2.1. Class structure is different in that and is not covered in this blog

This blog provides the step by step process to send an IDOC using JCO 3.0 and Java IDOC Class Library 3.0.

The Class BaseIDocInboundWrapper (Step 1) & IDocInboundWrapper (Step 2) can be reused for all the IDoc Types

Step1. Create a Class BaseIDocInboundWrapper

Sample Class Code for BaseIDocInboundWrapper

}

The above Step 1 and Step 2 code is generic for all the IDoc Type.

The main method in the above class demonstrates how this class can be used to send IDOC to the ERP System. There are 2 Ways in which the IDOC can be sent.

WAY 1: The user can create the custom structure of the IDOC and then can send the IDOC as IDocDocument.

WAY 2: The user can generate the XML File for the IDOC in a particular structure and then can parse the IDOC as IDocDocumentList.

Step 3. In this step I will be showing the WAY 2 for sending an XML File as IDOC for the IDOC Type. This step has to be performed individually for each IDOC Type. 

Before proceeding with this step, Create the beans with the same structure as that of IDOC Type that has to be sent to ERP System as this will be referenced in the Class that we will create in this step. The structure of the corresponding IDOC can be found by logging on ERP and with T-Code WE20.

Fill in the Values in the setter methods in each get... methods in the Class. This can be done by changing the method signature to accept parameters.

The main method describes how IDocReceiptXMLInboundWrapper Class can be executed. IDocReceiptXMLInboundWrapper  will internally call the classes created in Step 2 and Step 1.

For Converting the Object to XML, JAXB is used. 

After the program is executed with success message, Log in to ERP System and go to T-Code WE05. The IDoc should be visible there.
