Is RFC destination is required for accessing BAPI from java/VB program.

I am not able to understant that all BAPI are Remote enabled ,but no where I observed that RFC destination is required.
Can any body tell me exact flow and things step by step.
Any example/full source code so that I can call from java program.
I have tried some java code posted here but not able to understand ..
please provide me setttings also in SAP and java system

Hi Nagaraju,
Thank you very much. your post resolve one of my basic need .really appreciate your post.
I was not able to execute bapi BAPI_MATERIAL_GETLIST but I executed BAPI_PO_GETDETAIL succesfully.
Still I have 2 doubt.
[1]. I called BAPI function module(BAPI_PO_GETDETAIL) from simple java program,But I need to call API method ( GETDETAIL) created for this BAPI not direct BAPI function module.
[2] this is something apart from original topic.
I have tested your java code in java as well as similar in ECC 6.0
But I am not getting any output in JAVA program.
I am getting output in ECC6.0 only when I will take internal table lt_mara[] with header line.
if I will take separate workarea output is not coming. I think this is the problem in JAVA also.
Please see the code and tell me where I am wrong.

RFC Destination is required for R/3 receiver system

Hi All,
Is RFC destination required for R/3 receiver system? Scenario i,e File >XI> RFC
How XI system communicate with R/3 receiver system?
Regards,

Hi,
RFC dest is not required in this case, XI will communicate thru RFC channel which you will configure as receiver channel. Hence in this channel, you will mention the required parameters.
Please search this fourm and you will get plenty for blogs with step - to -step details of configuring the FILE 2 RFC scenario.

No RFC destination is maintained for the port 'SAPERP'

Hi!
I am facing with a very strange thing.
I am implementing a File_to_IDOC scenario.
Therefore I created in XI system the appropriate Ports in tcode IDX1.
I use one business system with two clients (SAPERB100 and SAPERB200).
I defined there of course the appropriate RFC connections (RFC_IDOCERB100 and RFC_IDOCERB200).
Unfortunately when I go into tcode IDX2 and try to load metadata I get the following error:
No RFC destination is maintained for the port 'SAPERP'
Message no. IDOC_METADATA455
Diagnosis
No RFC destination has been maintained for logging on to this system for the port SAPERP.
This means that no structure information can be provided for this port.
Procedure
Maintain the required RFC destination for this port.
Can some one help me to solve this problem?
Thank you very much!
regards
Holger

HI Holger
You need to have a RFC destination created for XI server type 3 (ABAP) to push IDOC from ECC. Similarly you need RFC destination in XI towards ECC to load IDOC / RFC metadata.
Thanks

Why do we need to define RFC destination and user for material replication

Dear Experts,
why do we need to define RFC destination and user for material replication? Here we use crm middleware only for material replication. Could you please help me to understand it?
regards,

Hello,
As far as I know, you can use the same RFC destination already available in ECC to SRM to replicate materials.
You can refer to note 720819.

The destination plugin required for this action is disabled.

Dear all, I am using Infoviewer first time and for testing purposes I uploaded our Lab rework report. The viewing side is absolutely fine however if I try to send the file via email, ftp etc it gives me the following error:
The destination plugin required for this action is disabled. If you require this functionality, please contact your system administrator.
I have looked on one of the forums where one user mentioned to restart the destination job server. I have tried that but it didn't work. It somehow looks like I haven't installed the plugins onto the server or maybe somewhere it has been disabled.
Could you please help.
Many thanks
Kind Regards

OK. From CMC, I can use do the following:
1. Go to Home>All Objects>
2. Select the object
3. Hit the History tab
4. Click Send to... and select FTP
This is explained on xir2_bip_Admin.pdf.
However, I can't do this via Infoview.
i.e.
When I try to send a file from the History it doesn't end up in the FTP location.
But what does work is if I select the report itself, the RPT format is sent to the FTP location.
This makes sense from a perspective that if you don't schedule a Crystal Report, you will not have a PDF version of it. On the other hand, whay wouldn't I be able to send it from the History selection on Infoview.

Any program for calling bapi from ABAP step by step

any program for calling bapi from ABAP step by step
points will be rewarded,
thank you,
Jagrut BharatKumar Shukla

Hi Jagrut,
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.
ex BAPI:
API_SALESORDER_CREATEFROMDAT1
BAPI_SALESORDER_CREATEFROMDAT2

<b>EG::</b>
<b>Here is the step by step procedure for creating BAPIs.</b>
There are 5 different steps in BAPI.
- Create BAPI Structure
- Create BAPI Function Module or API Method.
- Create BAPI object
- Release BAPI Function Module.
- Release BAPI object.
Step1. Creating BAPI Structure:
- Go to <SE11>.
- Select Data Type & Enter a name.
- Click on Create.
- Note: Always BAPI should be in a development class with request number (Not Local Object).
- Select Structure & hit ENTER.
- Enter the fields from your database. Make sure that the first field is the Primary Key Field.
- Then SAVE & ACTIVATE.
Step 2. Creating BAPI module:
- Enter TR.CODE <SE37>.
- Before entering any thing, from the present screen that you are in, select the menu
Goto -> Function Groups -> Create Group.
Enter a name (Note: This name Must start with ZBAPI)
Let this screen be as it is and open another window and there, enter TR.CODE <SE80).
Click on the Third ICON that says Inactive Objects.
Select the group that you just created and click on Activate.
Notice that the group you created will disappear from the list of inactive objects.
- Go back to ><SE37> screen and enter a name and hit <ENTER>. Then enter the group name that you just created and activated.
NOTE: When you release a function module the respective group will be attached to that particular application. It cannot be used for any other application. NEVER include an already existing group that is attached to another module.
Now click on the first Tab that says [ATTRIBUTES] and select the radio button that says remote-enabled module since we will be accessing this from any external system.
Then click on the second tab that says [IMPORT].
Enter a PARAMETER NAME, TYPE and the structure you created in the first step. Also select the check box Pa. All remotely enabled functional modules MUST be Pa enabled, where Pa means Passed by Value and if you dont select Pa, then that means it will be passed by reference..
Then click on tab that says [EXPORT].
Enter the following as is in the first three fields
RETURN TYPE BAPIRETURN (These 3 field values are always same)
Here also select Pa meaning Pass by value.
Note: BAPIRETURN contains structure with message fields.
Then SAVE and ACTIVATE.
Step 3. Creating BAPI object:
- Enter Tr.Code <SWO1> (Note. It is letter O and not Zero).
- Enter a name and then click on create. Enter details.
NOTE: Make sure that that Object Type and Program name are SAME.
- Enter Application M, if you are using standard table Mara. If you are using your own database then select Z at the bottom.
- Then hit <ENTER>.
- Now we have to add Methods. High light METHODS and then select the following from the menu:
Goto Utilities -> API Methods -> Add Methods.
- Enter function Module name and hit <ENTER>.
- Select the second FORWARD ARROW button (>)to go to next step.
- Check if every thing looks ok and again click on FORWARD ARROW button (>).
- Then select YES and click on <SAVE>.
- Now on a different screen goto TR.CODE <SE37>. Enter Function Module name and select from the top menu Function Module -> Release -> Release.
- Goback to TR.CODE <SWO1>.
Here select the menu combination shown below in the same order.
- Edit -> Change Release Status -> Object Type Component -> To Implemented.
- Edit -> Change Release Status -> Object Type Component -> To Released.
- Edit -> Change Release Status -> Object Type -> To Implemented.
- Edit -> Change Release Status -> Object Type -> To Released.
- Then click on <SAVE>.
- Then click on Generate Button (4th button from left hand side looks like spinning wheel).
- Then Click on the button that says PROGRAM to see the source code.
To check if this is present in work flow goto TR.CODE <BAPI>.
Here it shows business object repository.
- First click on the middle button and then select ALL and hit ENTER.
- Goto tab [ALPHABETICAL] and look for the object that you created. This shows that the BAPI object has been created successfully

Components required for sending Email from SAP [Kernel Release 46D]?

Hi All,
Can somebody please tell me the components and the Configuration settings required for sending Emails from SAP system[Kernel Release 46D] to the mail server[Win NT] using SMTP.
From note 455127, I understood that "Sap Internet Mail Gateway" is required and there are other settings to be done. (SAPconnect with RFC can only be used as the Kernel version is 46D)
It will be great if somebody can explain me in simple steps if He/She has done this before.
Thanks,
Varun

Varun,
sendmail comes with UNIX OS, there are versions of sendmail programs available for Windows too, but i guess you have to purchase them.
Another alternative is a discontinued product called SAP Exchange connector, if you have a Windows environment and MS Exchange server as your mail server, you could use a SAP exchange connector and get your SAP Email config done.

Siddhesh

Can any but help me out
Rajendra

Hi,
Are you using the standard iview. If that's the case you need to configure in the backend. Meaning you need to store the photo in the Org management(HR) which the HR functional guys will do. You just need to add the iview to your role.
Let me know if you require further informationn.
Award points if helpful.

Jintegra problem - accessing Matlab from Java??

Hi:
Sorry if this post doesn't belong here!!
I am accessing Matlab from JAVA using JIntegra for COM. I tried running the example in their website.
(http://j-integra.intrinsyc.com/support/com/doc/other_examples/Matlab.htm)
I have also posted the example below. I am using their trial version and have included all the jars as said. I get the an unexpected output (all zero's) for reading a variable in the matlab workspace. I don't understand why I get this. Can anyone let me know if this runs for you??
Thanks
Pavan
Example code from Jintegra website:
public class MatlabExample {
public static void main(java.lang.String[] args) throws Exception {
try {
// DCOM authentication: Make sure NT Domain, NT User, NT Password are valid credentials.
// Uncomment this line if MatlabExample.java remotely accesses MATLAB :
// com.linar.jintegra.AuthInfo.setDefault("NT DOMAIN", "NT USER", "NT PASSWORD");
// Create the MATLAB object
// Specify host name or IP address of MATLAB machine as parameter if
// MatlabExample.java remotely accesses MATLAB.
// mlapp.MLApp mlApp = new mlapp.MLApp("123.456.789.0");
mlapp.MLApp mlApp = new mlapp.MLApp();
String result = mlApp.execute("a = [1 2 3 4; 5 6 7 8;]");
System.out.println("Execute result is " + result);
double mreal[][] = new double[2][4];
double mimage[] = new double[0];
mlApp.getFullMatrix("a", "base", new Object[]{mreal}, new Object[]{mimage});
for (int i = 0; i < 2; i++) {
for (int j = 0; j < 4; j++) {

Try this:
1) Download JETCOMP.exe (freeware from Microsoft);
2) Put the following code in your app (assuming your database file name is: "DB.mdb"):
try {

Calling MS Access queries from Java

Anyone have any idea if it's possible to call MS Access queries from Java? I have a client who is insistent on keeping MS Access for their database, and it'd be nice if I didn't have to receate all their queries in Java.
I've successfully connected to and queried the Access MDB, but I need to know if it's even possible to execute the stored MS Access queries they have setup in the database.
Thanks!
