ALE-IDOC Scenario using Custom IDOCBy SachinDabhadeAim: Transfer the data from one system to another using user customized IDOC.

Sender System:Server: 172.25.8.185Client: 200Data from Z table: zsach1ReceiverSystem:Server: 172.25.9.198Client: 800Data from Z table: zsach1Data is fetched from Z table on the sender system and inserted it in the Z table of Receiver system using ALE/IDOC.Settings on the Sender EndTable Creation T Code SE11.

Defining the Basic TypeT Code WE30Click on NewThis will take you to next screen as followsHere you have connected the basic type to the segment type.Enter again and this will take you to screen as follows This shows the relation between the basic and the segment types.Next you need to make the entry of the segment in the system table.Tcode : WE81Next is the following entry which is required.

Here you are specifying the message type and the basic type and the release version.This is all about the configuration you need to do on the sender side.Now on the sender side you also need a program that will fetch the required data, couple it in the IDOC format and post it.Here is a small piece of code that could be useful.*&---------------------------------------------------------------------**&Report ZSACH_CUST_IDOC **& **&---------------------------------------------------------------------**& **& **&---------------------------------------------------------------------*report zsach_cust_idoc .parameters :p_logsys like tbdlst-logsys.data :gen_segment like edidd-segnam value 'ZSACH'.data :control_dat like edidc,gen_data like z1hdr .tables :zsach1.data: begin of inttab occurs 0,lname type z1hdr-lname,fname type z1hdr-fname,end of inttab.data :int_edidd like edidd occurs 0 with header line,int_edidc like edidc occurs 0 with header line.select * from zsach1 into corresponding fields of table inttab.ifsy-subrc ne 0.message 'no data' type 'I'.exit.endif.control_dat-mestyp = 'ZSACH'.control_dat-idoctp = 'ZSACH'.control_dat-rcvprt = 'LS'.control_dat-rcvprn = p_logsys.
