What is Mapping Look ups?

Can any one explain me what is mapping look ups in graphical mapping?

Hi,
There are three types of look ups u can do
RFC look up
SOAP look up
JDBC look up
What is Lookup and why we need:
Within an XI mapping it is a common requirement to be able to perform data lookups on-the-fly. In particular, there may be a need to look up some data that is maintained in an R/3 application.
In the error handling topic we have seen the different validations which need to be performed on file. This can be done through Lookup.
Some use cases:
Look up material number from table MARA.
Look up cost center budget.
Look up employee information.
Look up unit-of-measure (UOM) information from table t006a.
Lookup for raising an alert.
The purpose of the lookup may be:
To perform application-level validation of the data, before sending it to the backend.
To populate fields of the XML document with some additional data found in the backend application.
This is a form of value transformation.
The "value mappings" offered by XI are not adequate in this case, since the data would have to be manually entered in the Integration Directory.
There are two ways in which we can do lookup:
Call lookup method from GUI mapping.
Call lookup method from XSLT mapping.
Lookup method from GUI mapping can be called using any of the following ways.
RFC lookup using JCO (without communication channel)

What is meant by costing key?

Dear Experts ,
while releasing the billing document to accounts , i am getting error like
Valuation with material cost estimate: error, The system looked for the material cost estimate using costing key "002", as defined in the Customizing settings for CO-PA, incomplete due to FI/CO interface
what is meant by costing key?
regards
rajakarthik

Hi,
In Costing based Profitability analysis you define costing keys. A costing key is a set of access parameters which are used in valuation to determine which data in Product cost planning should be read. In the costing key you attach the costing variant.
In the costing key you specify whether the system should read the current standard cost estimate, the previous standard cost estimate or the future standard cost estimate or a saved cost estimate.
The configuration settings to determine this costing key is as follows:
Assign costing keys to the products u2013 Three costing keys can be attached to a single product for a specific point of valuation, record type, plan version.
Assign costing keys to Material types
Assign costing keys to any characteristics u2013 You can use your own strategy to determine the costing keys. This is through user defined assignment tables.

Look-Ups

Hi All,
1.Can you tell me what exactly the look-ups are?
2.Please tell me about the RFC and JDBC look-ups.
3.Also please tell me how many data types do I need to create for For JDBC <---> RFC sync ?
4.From my point of view I should create 2 data types ,2 message types for JDBC Request and JDBC Response while I can skip creating data types for Receiving RFC side.Is it?
Thanks in advance.

Hi Swetha,
1.Can you tell me about when are RFC,JDBC,CSV look-ups are used?
Look ups can be useful in any where, especially when we like to map the value that is reseided in some other application system and that value tend to change or get updated very frequently in that system .So as to get the recently updated values we prefer this .if it doesnot happen we cn directly go for hardcoding either by using Fixed values or value mapping.If the value is queried from R/3 we use RFC look ups.If the value is to be retived from Database we go for JDBC.
2.I think look ups are nothing but the User Defined Functions.Is it?Please tell me in detail.
Look ups need not not only Java functions we can do that in BPMs remember Filr to RFC to FIle using BPM scenario there we get values from RFC response too in Bpm .But this is again a performance issue with out using UDF.But its very easy to perform the lookups using UDF.Even SAP has provided good JavaAPI to perform lookups according to requirement.In most of the cases we use lookups for querying single values.But in PI7.1 there has been added advantage in the form of Graphical lookups to avoid java code and maintin reusability.The link was mentioned by experts already.
3.Please give me any scenerio about the implementation of RFC,JDBC,CSV look-ups .
I am giving example which i came across while working with EDI documents in SEEBURGER environment.There was a field value "TE" in some segment, while mapping to target i should get the Defintion forTE wich was maintained in some other data base and map to the target side, for that purpose we had to use JDBC look up and ping the data base to retrive the required value as the result of Lookup. So when i applied look up i got the value "TELEPHONE" for the code TE.The same way for FX the lookup result was FASCIMILE.Not only this for PLANTCODES and some other business related data we might need to use Lookups...Hope you understood my point.
Thanks,
Ram.

What's meant by an "Elementary Stream"?

Question as per the title of this post: What's meant by an Elementary Stream?
I looking for a product which will record to a compact flash card, and one of the suppliers has come back to me telling me their product records in Mpeg2 Elementary Stream only!
I think this means that the Video is an Meg2 file and the audio is encoded in a seperate file (ie: .aiff etc.)
Is this known as a demuxed file too?
Some clarification would be wonderful.
Thanks in advance.
Steve

You're correct on all counts - elementary streams are individual segments for video and audio that are meant to be played together. Demuxing a file is simply breaking it into those elementary streams.

What is meant by change pointer and change request

hi,
what is meant by change pointer and change request in sap r3
plz can u any one notes or link on this , or if possible briefly tell about this..
i am looking for clear idea on this..
thanks
Ruban

With respect to Dictionary Change pointers means all the changes done to dictionary objects.
All the change logs with respect to tables are stored in CDHDR and CDPOS table
Change Pointers in broad sense are used with respect to IDOC
Change Pointers & Reduction of IDOCs.
Applications, which write change documents, will also try to write change
pointers for ALE operations. These are log entries to remember all modified
data records relevant for ALE.
Following Steps must be followed in case of Change Pointer.
1) Goto Transaction BD60.
Note down the Details of the Message Type for which change pointer has to activate. Details like Function Module, Classification Object, ALE object Type etc.
E.g. ZDEBP3
2) Next step is goto transaction BD53
Click on change button.
First select the segment for which the fields has to modified (either remove or
add ).
It will show the fields in a pop-up window where the user can select, deselect the respective fields.
Save the settings for the Message type. Dont forget to activate the change pointers by clicking Activate Change pointers button on the main screen.
3) Once the activation is done system will reset the settings for the Message type in Change pointers (BD60). Maintained the old settings for the Message type.
Check this FAQ
. Do you really need change pointers?
You need change pointers to distribute changes with the ALE SMD tool. If you do not use this tool, you do not need to write change pointers.
You can deactivate change pointers and activate them again with the transaction BD61.
2. Do you really need to activate change pointers for this messages type?
If some messages types are no longer to be distributed by change pointers, you can deactivate change pointers for this messages type.
You can deactivate change pointers for the message type
and reactivate them again.
For reduced message types, deactivate the change pointer with the
Reduction tool (transaction BD53).
3. Are there still too many change pointers to be processed?
The change pointers are analyzed with the transaction BD21 or the report RBDMIDOC in ALE and flagged as processed. If the change pointers are created periodically, this report should also run periodically.
4. Are no longer required change pointers reorganized in time?
The report RBDCPCLR (transaction BD22) to reorganize the change pointer should run periodically. Depending on how many change pointers are created or processed, you can schedule the background job hourly, daily or weekly. You should delete all obsolete and processed change pointers. You can also use this report for specified message types.
We come across change pointer technique while dealing with master data distribution thru ALE/IDOCs
When we want to reflect changes made to master data(i.e customer master, vendor master, material master ...) visible to other clients listed in customer distribution model, we follow change pointer technique.
What is customer distribution model?
A customer model depicts various messages (master data, transactional data) exchanged between the systems and establishes a sender and receiver of data
A customer model is always maintained on any system for the entire distributed network of SAP systems, so it must be distributed to various systems in the distributed network.
These r some details regarding change pointer technique which u may find it usefull.............
The change pointers technique is based on the change document technique, which tracks changes made to key documents in SAP, such as the material master, customer master, vendor master & sales orders. changes made to a document are recorded in the change document header table CHDHR, and additional change pointers are written in the BDCP table for changes relevant to ALE. BDCPS table stores the status of changed documents processed or not.
The process for distributing master data using change pointers involves the following steps.
The application writes change documents. SAP maintains change documents for
several objects in the system, such as materials, customers, invoices, and bank data, to provide an audit trail for changes made to an object. A change document object represents a set of tables for which changes are recorded. For example, the change document for the material master is named MATERIAL and it contains the various tables of the material master object, such as MARA and MARC.
When an application transaction makes changes to an object, the application writes change documents, which are stored in the CDHDR and CDPOS tables for each change made to an object.
Tip
Execute transaction SCDO to see a list of change document objects and
their tables.
The SMD (Shared Master Data) tool writes change pointers. When changes are made to an object, the SMD tool checks the ALE settings and consults the ALE distribution model to determine whether a receiver is interested in the object that was changed. If the system finds an appropriate receiver, the system creates change pointers in the BDCP table that point to change documents in the CDHDR table.
The ALE programs analyze change pointers and generate IDocs. SAP provides
standard function modules that read the change pointer table and generate IDocs for the objects that were changed. These programs are designed to ignore multiple changes and create only one IDoc. For example, if a material is changed four times before the function module is invoked, only one IDoc with the latest data from the material master data is created. The function modules are invoked by a standard report, RBDMIDOC. The selection parameters of this report allow you to specify the message type for which change pointers are to be analyzed. Configuration
you must carry out the following configuration steps to enable master data
distribution based on changes to the object.
Step 1: Enable Change Pointers Globally
Transaction: BD61
This option enables the change pointer process globally. Make sure that the flag is checked.
Step 2 :Enable Change Pointers for a Message Type
Transaction: BD50
This setting is required for activating change pointers for a specific message type.
make sure that the Active flag is checked for your message type.
Step 3 :Specify the Fields for Which Change Pointers Are to Be Written
Transaction: BD52
For standard master data objects such as the material, customer, and vendor objects, SAP already provides a list of fields for which change pointers are written. If you are satisfied with the standard set of fields, you can skip this step. If you want to add new fields, you must add entries for the required fields. If you are not interested in IDocs being generated for changes to a particular field, you can remove it from the list. For example, if you do not want to distribute the
material master for changes made to the Catalog Profile (RBNRM) field, you can delete this entry from the table.
Step 4: Changing a Field in the Master Data
Change a field in the master data object for which the change pointer is enabled. For example, if you change the net weight of a material in the material master data, a change pointer is written.
Tip : You can verify a change document and change pointer by viewing entries in
tables CDHDR and BDCP, respectively.
Step 5 :Executing Program RBDMIDOC to Process Change Pointers
Execute program RBDMIDOC to initiate the process of generating an IDoc. On the selection screen, specify the message type. For example, you can specify MATMAS. After you execute the process, it displays the number of entries processed.
Note :
Normally, you schedule this program to run frequently and start IDoc
generation for different message types.
Step 6 : View the idocs in WE02/05

What is meant by EDI(Electronic data excahange)

what is meant by EDI(Electronic data excahange).my pm has given us new project on EDI based project.Iam not knowing EDI can any body tell or give any link to tutorial.

EDI is the predecessor to XML. It is a document format that is used to pass data between disparate computer systems.
There are many different EDI file formats (like X12) as well.
Did you try looking up Java EDI on Google?

What is meant by estimated costs and estimated rows in SQL explain (ST05)?

Hi
I was just wondering if someone could explain/clarify exactly what is meant by estimated costs and estimated rows in the 'explain' / execution path functionality of ST05.
For example, we could see a SQL statement was very inefficient accessing a table:
Estimated Costs = 6.006.615 , Estimated #Rows = 0
Does this literally mean that for 6 million costs / reads / effort, 0 results were returned??
Is this a ratio of efficiency?
We built an appropriate index and now we have:
Estimated Costs = 2 , Estimated #Rows = 1
A lot better! The job was taking 40+ hours and being cancelled; now it takes 5 minutes. So a 3 million times improvement sounds realistic...
However, we had another instance where the explain showed:
( Estim. Costs = 195.077 , Estim. #Rows = 538.660 )
and we built an index, and now the explain is:
( Estimated Costs = 41.867 , Estimated #Rows = 538.660 )
What exactly does this mean - as the costs has been reduced, but the rows is the same?
Thanks
Ross

Hi Ross,
>I was just wondering if someone could explain/clarify exactly what is meant by estimated costs and estimated rows in the >'explain' / execution path functionality of ST05
Take a look at note 766349, point 20.
>An EXPLAIN displays "Estimated Costs" and "Estimated Rows", which

So the costs and rows are values conjured up by the cost optimizer when calculating the access path that is most likely to be efficient. THEY ARE ESTIMATES!!!
>Does this literally mean that for 6 million costs / reads / effort, 0 results were returned??
As per the above, no. The costs and rows are estimated before the rows are fetched so there are no actual results yet.
>What exactly does this mean - as the costs has been reduced, but the rows is the same?
An efficient database access is exactly that; reads only the blocks that contain the rows it needs and nothing else. If the access is inefficient it will spend time accessing blocks that contain no data that is eventually contained in the result set.
This question would be better placed in the Oracle forum...

Peter

LOOK UPS situation

Hi,
          i studied all the links regarding LOOK UPS which are provided in the SDN .. but still i did't clear with this information..   when exactly we will go for lookups.. i means in which situation we will go for lookups..( i studyed that lookups will interrupt the mapping and interact with the database and access the data from the database in the mapping time..)   but in what scenario we need to get the data from database...give me a simple example..
       can any body give me a brief idea abt LOOK UPs..

What are the functions of look and feel files?

Hi,
If some one can explain me what are individual role in look and feel of the ISA B2C application.
mainFS.jsp
main_inner.jsp
catalogFS.jsp
accountFS.jsp
refresherB2C.jsp
I want to know function of each files. If I change any file then where exactly I can see changes which I made.
Any help from any one highly appreciated.
Thanks.
Ashish

Hi,
If you get hold of the ISA Development and Extension guide there is a section highlighting which frames go where in the main application.
You can also see which .jsp pages are displayed where by adding the following parameter to the root URL of the application when you logon.
http://<host>:<port>/b2c/b2c/init.do?showmodulename=true
This will display the name of each jsp page in the frames on screen.
Also, surely you must have been asked to change certain aspects of the application - not specific files? You shouldn't just change the files and then "see what happens"...
Hope this helps,
Gareth.
