Regarding an Interface

I had a debate with regards to the definition of an Interface.
Can I call an Interface an object?.Far as I know,everything in Java can be called as an Object.
Am i right?.

Source: SCJP Book by Kathy and Bert(310-035),Chapter 07,page 406.
"Youre an object. Get used to it. You have state, you have behavior, you have a job.
(Or at least your chances of getting one will go up after passing the exam.) If you
exclude primitives, *everything in Java is an object*. Not just object, but Object with
a capital O. Every exception, every event, every array extends from java.lang.Object".
This has driven me into believing that everything except primitives is an object.Did I understand it wrong?.It depends what you mean by "everything". All the things I listed above are part of Java but are not objects.
Apparently this book is only referring to things that hold values, but even that's not right, since objects are not part of Java's type system. Only primitives and references are.
Don't get so hung up on it. What difference could it possibly make to how you write your code if "everything is an object" vs. "not everything is an object."

Facing some issue regarding Requisition interface table

I am facing some issue regarding Requisition interface table..
Purpose: we have to massage data & create massage data & create Requisitions.
Issue Detail:
Before:
Previously it was Auto Create Purchase Requisition
On the move transaction form step 10 to 20, this step will trigger creation of requisition.
and Creating Requisition successfully.
After:
After stopping Auto Create Purchase Requisition functionality the Requisition interface data is not getting populated in the Requisition Interface tables as well.
Please provide your inputs.

It's standard functionality not to populate the req interface while you don't want to autocreate.
Thanks,

Regarding Message Interface , Service Interface

Hi All
My scenario is File to File from 1 application server to another application server ,without any transformation in PI 7.1 for service interface to be involved for Interface Pattern Stateless and Stateless (XI 3.0) compatible can only be used with Category Abstract
only abstract catgory is possible , can'nt i make 1 outbound & another inbound for this ?

Regarding message interfaces in JDBC implementation

Hi Bhavesh,
I have been trying to implement the jDBC scenario as mentioned by you in the blog "JDBC Receiver Adapter -- Synchronous Select Step by Step",could you please help me out with interfaces(how many interfaces do we need on the whole).
Regards
Madhu

Madhu,
Please refrain from directing questions to someone in particular. There are lots of XI experts around here who can surely help and directing questions to one person is going to discourage others from answering .
Answering your question~~ refer into this blog by Arpit and use the same concepts as he has described for File - RFC - File. The only difference will be in the datatypes and message types,

Regarding XIF Interface and Sale Transaction in CRM

Hi,
I have done the configuration in CRM system using XIF interface to communicate with other system.
We are in the process of implementing CRM, Product and Partner data has to upload in CRM. We are not using R3 for anything.
When i create a sales transaction using transaction code CRMD_ORDER,System allow me to save/create a business transaction even though i can see the error attached to it and at the same time I can see the BDOC number in SMW01.
But i dont see any relevant OUTBOUND IDOC against the BDOC, evenif i have configured it for external system and I was expecting Outbound IDOC with error status, please correct me if i am wrong.
I am using WE02 and WE05 to see my outbound idoc and i have not found anything here.
Am i missing some step in configuration which is required for converting BDOC to IDOC, Please suggest me.
Steps which i followed to configure the system are
1. Create a suitable RFC destination in the SAP IMG Define Target Systems for RFC Calls .
2. Create a logical system.
3. Create a receiver port (transactional RFC) in SAP IMG Define Port, indicating the RFC destination you created earlier.
4. Create a partner profile, for example, partner type LS with the partner number CRM_XML_BC, in the SAP IMG Maintain Partner Profile Manually.
5. Enter all outbound parameters for the logical system CRM_XML_BC in Create Outbound Parameters in the Outbound Parameters window .
6. Create a site (transaction SMOEAC). To do this, select Object Type Sites and Create Object. Assign your site a suitable name and select Site Type External Interface for IDocs. Assign the partner profile created previously as a Site Attribute.
7. Use object type Subscriptions to maintain a subscription for publication of the object with the predefined site.
8. Create an entry for the new site using XIF customizing transaction CRMXIF_C1 via F4 help (BDoc Type = <objname>, IF Type = 'CRMXIF_*_SAVE_M', Set relevant flag for complete Data and Return). The flag Flag for complete data is only relevant for the objects "order", "business partner", and "business partner relationship". It flags whether only delta changes or the object instance should be transferred completely. The object "business document" is always sent completely, regardless of flag status.
Thanks & Regards,
Manoj Tiwari

Hi Joao,
Thanks alot for your quick reply.
Yes i have selected "post it immediately" instead of "collect Idoc". should i select "post it immediately"??
About the Outbound parameter i specified everything like message type (crmxif_order_save_m), port , RFC destination of type R3 since we have SRM system, basic type (crmxif_order_save_m01), package and post the idoc immediately.
Here in our distributed environment we are sending data from CRM to SRM, means our target system is SRM.
I have created the Site of site type "External interface for idocs" and give the partner Number of SRM system and created subscription too as part of XIF setup.
Please reply me if i am going wrong in my approach.
Thanks & Regards,
Manoj Tiwari

Regarding SAP interface inforamation.

Hi All,
I want to know some basic information about interfaces as :
1) Where we can check, is particular interface is active or not?
2) What type of master data does the IDoc contain (i.e. material master) ?
Awaiting for your kind reply.
With Regards,
Preeti.

Hi Preeti,
In the first place, what type of interface are you looking for whether interfaces within SAP like SAP PP-WM / PP-QM etc. or whether an interface from 3rd party systems to SAP?
To your second question about the contents of the IDOC Master data, if you have the document already created goto tcode WE02 enter message type, date and time parameters and execute. Then check the individual EDI segments - Header and Detail segments. This will be based on standard EDI format.

Regarding Conditional Interface Determination

Hi All,
I need small confirmation on behavior of conditional interface determination,
My source message is like below
<?xml version="1.0" encoding="UTF-8"?>
<PROS_CustInfo><Structure>
                                  <name>ABC</name>
                                   <data>100</data>
                             </Structure>
                             <Structure>
                                  <name>XYZ</name>
                                   <data>101</data>
                             </Structure>
</PROS_CustInfo>
I am having 2 Receiver RFC messages for same receiver.
If name=ABC then i need to send this data(ABC, 100) to first RFC by using 1st mapping else
if name=XYZ then i need to send that data(XYZ,101) to second RFC by using 2nd mapping.
But in my message name contains ABC and XYZ also. Now how conditional interface determination bahaves. Will it execute 1st mapping or 2nd mapping or both.
If you find any related post please share.
Thanks,
Madhusudhan

Hi Madhusudhana,
because of the problem, that only one condition can ever be true at runtime, you can avoid this by using count function. Because you can't build a Statement like count(xy) > 1 with ExpressionEditor of SAP PI, you have to use this expression with SAP PI:
/PROS_CustInfo[count(Structure[name='XYZ'])>=1] EX
This condition works on whole document.

Regarding Component interface controller

hi all
Can anyone explain me use of Component Interface Controller under Component with example.
Thanks in advance
Imityaz

Hi,
Interface Controller
One Web Dynpro Component may declare the use of another Web Dynpro Component to form a u201CParent-Childu201D usage relationship. In such cases, the only point of interaction between the parent and child components is the functionality found in the childu2019s interface controller.
if an interface controller is part of a component interface, the controller editor is in change mode and the context, the events and the methods can be implemented and edited directly.
Refer this thread,step by step procedure is there.

Regarding Message Interfaces

Hi Guys,
I am new to SAP XI. Only thing I know is Message Interfaces are very key role to play in SAPXI. In case of any IDOC Are BAPI you can directly import them to I.R as interface objects. for example there are lots of IDOCS Available like BATMAS, MATMAS, ORDERS, CREMAS, there is lot of confusion on this what information this IDOCS contain how can we Know that particular IDOC contains the information Meeting our requirement. In case I am integrating MM Module Are SD module with SAP what interfaces I need to use pls any one explain me with clear scenario. and also pls help with some realtime docs so I can understand the things better. Thanks in advance.
Regard's
Kiran.B

Hi Kiran,
       There is no confusion about IDOCs. The requirement shows the what type of IDOC u want to used.
The XI guys will take care of the Import the IDOC from particular R/3 system.
Like same RFC Function Modules also..
When ever we used IDOC we need configured setting in R/3 & XI Systems.
__Configured steps in R/3 System:__
1) RFC Destination-- SM59
    --> Create the RFC Destination
   --->Crate the RFC Destination type 3(R/3 system)
   ---> specify the server address of the Integration server as target hosts
2) Port----WE21
   _---->Create the port for transaction RFC
> Enter the RFC Destination
3) Partner Profiles--WE20
Configure the steps in XI System:
1) Create the RFC destination (SM59)
2) Create the IDOC port into IDOC adapter(IDX1)
3) Load the meta data of IDOC into IDOC Port(IDX2)

Doubts regarding Inbound Interface

Hello All,
Im trying to import item categories into base table mtl_item_categories... for that in plsql program
1) i loaded data into staging table
2)performed some validations
3)inserted into interface table-- mtl_item_categories_interface
After this should i call the api INV_ITEM_CATEGORY_PUB.Create_Category_Assignment explicitly or not?????????
Thanks in advance.
Edited by: user13552077 on Jun 29, 2011 12:50 PM

Hi,
In order to import Item Categories from interface table (MTL_ITEM_CATEGORIES_INTERFACE) to base table, please run the concurrent program using below navigation, this should create item categories in inventory.
Inventory>Items>Import>Import Item Category Assignments.
Excerpts from previous post: ------------
Hi before using the mtl_item_categories_interface you have load all the ietms into inv with the help of mtl_system_items_interface when you do this automatically a default category id and category set_id will be assigned to the loaded items. so when you try to insert it wont take it. instead you have to update the category and category set id if necesaary..so the status should be update and you should provide the defalut category and category set id and along with the desired category id and category set id which you wish to populate. still facing the issue post me ur code I will correct it as i already did this conversions

Regarding QM interfaces

Hi All,
I have to develop QM interfaces...The Scenario is as below.. Please guide me how to proceed
1. Once inspecton lot completed, data has to go to external system in table format.
2. After that results recording and UD has taken care in the external system
3. Once results are updated with ok, UD has to update automatically in the SAP system
4. In case of rejection, defects will send to SAP system and based on defects need to update Notification in SAP system
5. After that notification need to send to External system.
6. I have to send master data like characteristics, Catalogs, sample procedures and sample scheme
Pls help me how i have proceed....
I already check with QM-IDI interfaces, but Results updation and UD updation and Notification updation will automatically done, this purpose will solve.
If it solves pls provide me the techniqes to handle these QM-IDI secenarios...
