ALE Configuration Needed

Question

Hi every one,
I want steps involved in ale configuration.
Lets take example two systems are Sysa and sysb
Thank you

Answer 1

hi
CATSDB CUSTOM IDOC TRANSFERMATION BETWEEN 2 DIFFERENT APPLICATION SERVERS
For this scenario Client 800 of application server SAPADM is the Sender and client 800 of application server SAP-REMOTE is the Receiver
1. Creating Logical Systems
o       Login using 800 client
o       Go to T. Code SALE
o       Expand Sending and Receiving Systems
o       Expand Logical Systems
o       Click on Define Logical System
o       Click on New Entries
o       Create CATSSENDER, ECC Logical Systems
o       Save and come back
o       Assign the CATSSENDER Logical System to client 800 of Application Server SAPADMAssign the ECC Logical System to client 800 of Application Server SAP-REMOTE
2. Creating the RFCs
o       Go to T. Code SM59
o       Expand R/3 Connections
o       Enter RFC Name as CATSSENDER
o       Connection Type as 3
o       Language as EN
o       Client as 800
o       User as SAPUSER
o       Password as YESV13
o       Target host as SAPADM
o       Click on Remote logon button to test the RFC
o       Enter RFC Name as ECC
o       Connection Type as 3
o       Language as EN
o       Client as 800
o       User as SAPUSER               
o       Password as YESV123
o       Target host as SAPADM                                                                               
o       Click on Remote logon button to test the RFC
3. Creating the Message Type
o       Go to T. Code WE81
o       Click on change, continue
o       Click on New Entries button
o       Give message type as ZCATSTIME and description
o       Save and back
4. Creating the Segment
o       Go to T. Code WE31
o       Give segment name as ZSEGMENTTIME
o       Enter Short Text
o       Enter the Field Name and Data Element in the text boxes
o       Save, continue,
o       Click on Edit -> Set Release
5. Creating the Basic IDOC Object
o       Go to T. code WE30
o       Give obj. name as ZTIMEIDOC
o       Click on create
o       Select create new radio button, give description and continue
o       Select the IDOC obj name and click on create button
o       Enter the segment name which is create earlier
o       Select the check box if you want to make the segment mandatory
o       Enter 1 in minimum number 99999 in maximum number, continue
o       Save and backo       Click on Edit -> Set Release
6. Creating Customer Distribution Model
o       Go to T. Code BD64
o       Click on change and Create model view button
o       Enter the short text and Technical name as CATSSENDER
o       Select the model and click on Add Message Type Button
o       Give the Sender as CATSSENDER,
o       Receiver as ECC,
o       Message Type as ZCATSTIME
o       Select the model view & click on Environment -> Generate Partner Profiles
o       Select Transfer IDOC Immediately and Trigger Immediately radio buttons
o       Click on Execute
o       You should get a list in green color which means it executed successfully.
o       Back to main screen, select the model view
o       Click Edit->Model view->Distribute
o       Click on continueo     
You should get a list saying model view is distributed successfully.
7. Checking the Port
o       Go to T. Code WE21
o       Expand Transactional RFC
o       Find the port from the list which is created using BD64 for ECC (Receiving system) RFC Destination.
8. Checking the Partner Profiles.
o       Go to T. Code WE20
o       Expand Partner Type LS
o       Select the Partner profile ECC
o       Double click on Message Type ZCATSTIME in Outbound parmtrs.
o       Check Receiver Port is assigned correctlyo     
Check the Basic type as your Basic IDOC object.
9. Assigning the Message Type to Basic IDOC Object
o       Go to T. Code WE82
o       Click on Change & continue, New Entries button
o       Give the Message type as ZCATSTIME
o       Give Basic Type as ZTIMEIDOC
o       Release as 4.6C
o       Save and back10. Creating Inbound Function Module (Posting Program)
o       Go to T. Code SE37
o       Create a function Module ZCATSDB_TIMESHEET_SURESH
o       Set the Processing type as Remote Enabled Module and mode as start immed, in Attributes Tab.   
o       Import Parameters
          P_WORKDATE                    LIKE               CATSDB-WORKDATE
          P_COUNTER                        LIKE               CATSDB-COUNTER
          P_LSTAR                               LIKE               CATSDB-LSTAR
o       Export Parameters
o       Tables 
             S_PERNR                      LIKE           ZCATSPERNR
[PERNR is select option parameters in ZCUSTOMIDOC report program so that it should be passed to function module ZCATSDB_TIMESHEET_SURESH in tables section. And also in tables section we used ZCATSPERNR, which is a global structure, which contains four fields as
Ø     SIGN
Ø     OPTION
Ø     LOW
Ø     HIGH]
o       Exceptions

CALL FUNCTION 'ZCATSDB_TIMESHEET_SURESH'
  EXPORTING
    p_workdate = workdate " passing workdate parameter
    p_LSTAR = LSTAR
    p_counter = counter
  TABLES
    s_pernr    = pernr. " passing pernr select option
IF sy-subrc EQ 0.
  MESSAGE i000(zaluri) WITH 'IDOCS CREATED FOR EMPLOYEES BETWEEN' pernr-low ' AND ' pernr-high .
MESSAGE i000(zaluri) WITH   'IDOCS CREATED FOR EMPLOYEES BETWEEN' PERNR-LOW 'TO' PERNR-HIGH.
gives information message if idocs are created for given  employees
ELSE.
  MESSAGE e000(zaluri) WITH 'NO IDOCS CREATED FOR EMPLOYEES' pernr-low  'TO' pernr-high. " gives error message
" if idoc is not created
17. Transferring the CATSDB records from sender Application Server SAPADM   to  receiver Application Server SAP-REMOTE
-         Execute Report Program ZCUSTOMIDOC
-         Give the Range of PERSONNEL NO'S, Date, Activity Type, Counter to Transfer
-         Give Message Type as ZCATSTIME
-         Give Receiver Logical system as ECC
-         Execute
-         You should get the IDOC Number
-         Take the IDOC Number and go to T. Code WE05 & Execute
-         In Outbox you can see the IDOC Status
-         Select the status record in left side window
-         Double click on the Status record in right side window-         You can see the Control Record, Data Record and Status Records for that IDOC
If the ICON is green and the status code is 3, it means the IDOC is passed to PORT Successfully
18. SENDING IDOCS FROM APPLICATION SERVER SAPADM
TO APPLICATION SERVER SAP-REMOTE USING WEDI
-         Go to T. Code WEDI & execute or T. Code WE19
-         Give idoc number it is generated recently
-         Continue & double click on segment to view data in segment
-         Click on EDIDC to give port, partner no, message type, partner
type of receiver. [For sender no need to give any port no leave it as
blank]
-         Click on Standard Outbound Processing button and click continue
-         You will get a message as idocs successfully transferred
Now Login in Receiver 800 client
-         Go to T. Code WE05 & Execute
-         You can see the status record in left side window
-         If the status no is 53 and color is green, it means the IDOC is posted to Application successfully.
-         You can see the Log Information by double clicking on the status record in right side window.
-         Now in left side window, you can see the Control Record, Data Record & Status Record of the IDOC
-         Now go to T. Code SE16
-         Give the table name CATSDB & press F7
-         See the contents of the table
-         The table is updated with the catsdb records transferred from 800 client with our selection program.
reward if u find useful
