What is the use of Design Time Repository?

Hi Gurus,
What is Track?
What is DTR? and what it offers ?
what is CBS? and what it offers?
What is CMS ?and what it offers?
Please Give me some idea about this?
Thanks in Advance,

SAP NWDI is also known as SAP JDI (Java Development Infrastructure). The latter term is considered to be obsolete.
NWDI consists of
- Design Time Repository (DTR)
- Component Build Service (CBS)
- Change Management Service (CMS)
The concept of the NWDI starts with a product and a software component (SC). The normal case is to have a one to one relationship between product and software component, one product is being developed and the relations between the components comprising the product are kept within a software component.
A software component comprises one or more development components (DC). A development component consists of a normal project created with the Netweaver Developer Studio, i.e. a Web Dynpro application. The software component can also have dependencies to other SCs.
All relations are defined in a SLD.
Since all DCs that makes a product is kept inside a software component, the relations between the DCs are intact and versions of the different DCs are always consistent in the SC.
To be able to develop a DC inside a SC, a Track has to be set up in the NWDI to support that development.
Details about the components:
Design Time Repository (DTR)
The DTR resemblance a filesystem and can be accessed via WebDAV. File and folder permissions can be configured for users or groups.
Each file is version controlled and it's possible to branch or merge files.
The main repository folder (ws) contains folders representing tracks in the NWDI. The files checked into the NWDI are files with no local dependencies. For instance, the classpath file in a project refers to local jar files and are of no use for the Component Build Service when the project is build on the server.
Component Build Service (CBS)
When a file is changed in the Netweaver Developer Studio, an Activity is created together with a Request. When the changes are done, the request is checked in to the DTR, the activity is then activated which trigger the CBS to build the DC on the NWDI. Usually an ear or war file is created. When the activity is released from the Netweaver Developer Studio, the ear or war file is deployed to a development system via the CMS.
When the CBS finds dependencies between DCs inside the Track, all dependent DCs are rebuild automatically.
It's possible to use the CBS to rebuild a DC or even a full SC.
Change Management Service (CMS)
Change Management Service is used to maintain tracks and keep track of what version is deployed on different servers in the landscape. CMS can also transfer code between tracks. This is often used when creating tracks supporting development of general components, development of main components and finally maintaining deployment of full solutions.
Transferring code between tracks in order to achieve merge and joins between deployed production versions.
The CMS consists of layers on each track.
Check-In - where initial source is loaded to the track.
Development - represents the deployment to a development system. Changes are deployed on a DC level.
Consolidation - represents the deployment to a consolidation system.
Assembly - Stage to accept a change. Combines all DCs to a full SC. Version number labels are possible to set here.
Test - represents the deployment to a test system. Changes are deployed on a SC level.
Confirm - Confirmation stage before moving the change to production.
Production - represent the deployment to a production system.
System State - Gives an overview of the different versions deployed on different systems.
Each layer have a history and the possibility to go back to an earlier state.

Does changing report connection at runtime require the same user/pwd used at design time?

I've recently integrated Crystal 13 into a web service to provide HTML reports served up within our web application. Sometimes reports would work and other times they would fail when attempting to connect to the database. The ConnectionInfo associated with the tables referenced in the reports bore the account info used at design time (in the Crystal IDE), what ever connection was set as the Datasource Location, this would include the server name, database name, and other attributes of the connection.
I found that any changes I make to table, sub-report connection info have no affect unless the UserID and Password match the UserID and Password saved with the report during design time. While generally searching online, I came across several references to this being and issue or suggestion when database connection problems dynamically running reports.
If this is by design?
How would I support customers who want to use my reports, but also require that they manage the db access accounts?
Thanks,
Jeff

Hi Brian, thanks for the response.
It does make sense that subreports would not necessarily be constrained to the same connection as the container report, and the designer would not persist a password for any stored connection.
I'm on Windows 7 and up, Crystal 13 runtime, C# web service, sql 2008 r2 and up (native client).
After loading the report source, I call ReportDocument.SetDatabaseLogon to set userId, password, serverName, and databaseName pulled from web.config. I then pass the connection info and the ReportDocument to a recursive call that applies the connection info to each table in the report and each table in any subreport.
Based on your description, it sounds like I may be missing, and require, the SetDatabaseLogon call on each subreport (ReportDocument).
This seems to ring true and I think coincides with your description. Would you agree?
Thanks,
Jeff

In repository what is the use of communication channel templates

Hi People
what is the use of communication channel templates in integration repository? and when we are using that please tell me the ASAP
Thanks & Regards
shekar

HI,
The communication channel template is for the documentation purpose that will give the information about the sender and receiver communication channels in IR. So No need to goto ID and check the related CCs each time for every scenario.
You can preconfigure a communication channel with a communication channel template. You can use the communication channel template as a template to define a communication channel at configuration time.
If you want to create multiple communication channels with some identical configuration data, you should use a communication channel template.
Thanks

What is the use of Condition is Query Designer ??

What is the use of Condition in Query Designer ??
How to use condition in Query Designer ??

Hi,
Conditions in a query can be defined for both characteristic combinations and key figures.
Characteristic combinations can be used using the ranking list functionality (e.g Top N or Last N customers with highest sales).
Key figures can be assigned the value limit conditions ( for e.g. display only rows in the query for which the key figure > 10 ).
For your specific requirements in which you need to display only a limited set based on the key figures, then you can go for conditions.
The conditions can be allowed to work on all the drill down characteristics independently, single characteristics or combination as well based on your requirement.
While execution the report, you can activate or deactivate the condition anytime by right clicking on the data cells.

Design Time Repository question.

Hi, I'm clustering my SOA Suite per a consultant and this documentation:
http://download-west.oracle.com/docs/cd/B31017_01/core.1013/b28939/j2ee.htm
In section 3.1.19 Configuring JNDIs for the Topic and Topic Connection Factory, it states:
Using Oracle Enterprise Manager 10g, follow these steps to configure JNDIs in the Design Time and both ESB repository instances.
Now I've followed these steps for the ESB repository, but I find it unclear as to what it's referencing with the "Design Time repository".
I'm having an issue where the SOAP WSDL's pull up without problem, but the SOAP Endpoint URI's always fail, and I'm wondering if this may have something to do with it.
Thanks for your help!

Hi Paolo,
I am doubtful about the use of NDS. This is because the libraries available with NDS will be for WAS 6.40 and EP6 SP2 i feel is on WAS 6.20. I am really not sure about this but my main point is that there may be library version conflict issues.
I dont think there is any plugin available for DTR.
But then DTR is a WebDAV based server. Hence any WebDAV client should be able to solve your purpose.
But this is a good thread. Hope others will also provide their suggestions on this.

What is the replacement for design view in in flex builder 4.7 for cs extension builder?

Because design view is not available in flash builder than what is the use of extension builder in UI designing now we have to do design UI with xml which is very time consuming and boring if there is any replacemnt for it than please help me .1 more thing i want to know is that when i make new default project in extension builder(flash builder 4.6) than it also not able to load design mode errror is
C:\Program Files\Adobe\Adobe Flash Builder 4.6\eclipse\plugins\com.adobe.cside.libsinstaller_2.0.0.4-33034\archive\cslibs\2.0\4.5\re lease\apedelta.swc- not respondingSWC file failed to load. Any component dependent on this SWC file will not be displayed in the Design Mode.The SWC may have failed to load because of:
* Incompatible definitions caused by usage of a different SDK version
* Missing referred class definitions

I have researched this quite considerably and my understanding is that Adobe have no intention of supporting Design View any more for Extension Builder. In my opinion a very disappointing decision and one that is hard to comprehend.
The best workaround I can find is to create the majority of your design in a parallel, non Extension Builder, project and then convert/import your design into your Extension. This is by no means as satisfactory as having Design View for the Extension you are writing but it is better than simply creating your layout by guess work/trial and error.
Although this has not been announced by Adobe, I have a suspicion that the reason they have decided not to put any further resources into fixing Design View is that Extension Builder as we know it is going to be abandoned soon, probably replaced with an HTML5/JavaScript method of building extensions. My concern with this is that, other than wanting reassurances that there will be backward compatibility support for old extensions, There will not be a way of compiling an extension in a way that prevents people from seeing your code.
This is all speculation and I guess we will have to wait and see what happens. Hope this has helped.

What is the Use of Imported Archives in Mapping Objects

Hi All,
What is the Use of Imported Archives in Mapping Objects ( IR )
Regards
Vamsi

Hi Vamsi,
When we are doing JAVA , XSLT mappings we have to do import archievs
after developing the JAva mapping in NWDS and create jar file come back to IR under imported archieves we will import the jar file.
Similarly XSLT als make the zip and import under imported archieves
Also when we have any java packages ,import it under archieves and make them to use in UDF

What is the use of custom service in doe?

Dear Experts,
what is custom service & what is the use of that. any one would you please explain?
Thanks & Regards
Ashok Reddy Jalapu

Hi Asok,
Custom Services are services which are implemented by application developer or consultant during design time and plugged into SAP standard software to perform specific task.
These services are based on the customer requirements and is included into the flow blue print (standard flow defination of a data object).
For eg : While performing Delta-download, you need to archive some data in DOE based on their business requirements.

What is the use implemention of work flow

Hi guis,
can u plz tell me what is the uses, u implement a workflow, and also please give the one scenrio on purchase order or invoice or anything, one scenrio explain me.

Workflow is a tool for automating the business process so that the process itself flows smoothly, without bottlenecks and without dead ends. Critical parts of the process can be streamlined with deadline monitoring and contingency options. Participants are informed of milestones in the process. The process definition itself is powerful enough to allow business re-engineering with re-training and to eliminate the impact of workforce changes on the basic business process.
SAP Business Workflow is the R/3 tool for handling the process automation within R/3 or between R/3 systems and other systems involved in the business process. It is flexible enough to handle ad hoc processes such as the circulation of an electronic document. It is robust enough to handle mission critical process in the production system such as the creation of a material master.
The different R/3 applications supply standard workflows for the commonly occurring processes. Once these workflow templates are activated, they are ready for immediate use. A complete set of workflow tools, including the workflow editor and workflow generation wizard, are provided to enhance these standard workflows or create new workflows. These tools are complemented with transactions for monitoring, tracking and the statistical analysis of the processes.
Because the business process often does not step at the R/3 boundary, various interfaces and third party tools are available for extending the process across systems.
Workflow is the technique for automating business processes. It is particularly beneficial
u2022 when different people are involved in different parts of the process
u2022 when a process only occurs sporadically and the users need to be reminded of what they need to do
u2022 when the duration of the process is critical and deadlines have to be met
u2022 when the process definition is likely to change on the fly and retraining users is not possible.
By automating the process, you free the users from having to know what to do when. Work items are sent to the participants notifying them of what they have to do, and a single click on the notification calls the correct transaction and navigates to the relevant screen.
When the workflow runs it creates work items which are like e-mails, but
u2022 they have the advantage that they contain the intelligence needed to execute the relevant task with the correct data when the operational user executes them,
u2022 they provide their own functionality so that the operational user has access to everything that is useful to improve the flow of the process,
u2022 they disappear on their own when they have been executed by someone else or made obsolete.
These work items can be received in the R/3 business workplace, MS Outlook (or any other MAPI compatible client), Lotus Notes, or work item notifications can be distributed by e-mail.
SAP Business Workflow:
u2022 accelerates the workflow across applications, functional areas, organizational units, and time periods,
u2022 supplements the integrated management of processes in the SAP System with individually tailored options for automating and actively controlling business and communication processes,
u2022 combines integrated organizational management with flexible assignment of tasks and responsibilities to locations, positions, jobs, groups, or individuals,
u2022 actively supports a quick implementation of workflow technologies through predefined workflow templates, Workflow Wizards and flexible adjustment options,
u2022 integrates every employee in the value chain by providing a versatile integrated inbox ("universal inbox") at their work centers that can be configured individually,
u2022 provides a Workflow Information System that is the foundation for process change management and continuous business engineering,
u2022 was designed to be a change-management tool,
u2022 simplifies continuous business engineering and process change management with user-friendly tools for defining and dynamically changing workflow tasks
u2022 conforms to the workflow standards of the Workflow Management Coalition (WfMC)
u2022 interfaces to other mail clients such as Lotus Notes and MS Outlook

What is the use of CM relevance field in DMS ?

Hi DMS gurus,
What is the use CM relevance field in DMS ?
Is there any specific scenario ?
Regards,
Sunny

Hi Sunny,
Usually CM (Configuration Management) is used when lifecycle phases come into picture as in lifecycle phases each phase has its own configuration which has to be maintained.
During their life, products and projects go through various life-cycle phases such as engineering and design, sales, production, and maintenance. In each life-cycle phase, a product has different configurations. A configuration is made up of multiple different objects that describe the product in the relevant life-cycle phase. For example, these can be documents, materials, BOMs or other objects. The grouping of objects changes over the course of time and is different from life-cycle phase to life-cycle phase.
Configuration Managment can be very much used when we make use of ECR/ECM (engineering change request/engineering change order) linked with DMS.
Thank You,
Manoj

WHAT IS THE USE OF COPY/MATCH OPTION IN BUISNESS CONTENT

WHAT IS THE USE OF COPY/MATCH OPTION IN BUISNESS CONTENT GIVE DETAILS

Hi,
Match (X) or Copy
If the SAP delivery version and the active version can be matched, a checkbox is displayed in this column.
With the most important object types, the active version and the SAP delivery version can be matched.
From a technical point of view, the SAP delivery version (D version) is matched with the M version. As in most cases the M version is identical to the active version (A version) in a customer system, this is referred to as a match between the D and A versions for reasons of simplification.
When a match is performed, particular properties of the object are compared in the A version and the D version. First it has to be decided whether these properties can be matched automatically or whether this has to be done manually. A match can be performed automatically for properties if you can be sure that the object is to be used in the same way as before it was transferred from Business Content. When performing matches manually you have to decide whether the characteristics of a property from the active version are to be retained, or whether the characteristics are to be transferred from the delivery version.
Example of an automatic match
Additional customer-specific attributes have been added to an InfoObject in the A version. In the D version, two additional attributes have been delivered by SAP that do not contain the customer-specific attributes. In order to be able to use the additional attributes, the delivery version has to be installed from Business Content again. At the same time, the customer-specific attributes are to be retained. In this case, you have to set the indicator (X) in the checkbox. After installing the Business Content, the additional attributes are available and the customer-specific enhancements have been retained automatically. However, if you have not checked the match field, the customer-specific enhancements in the A version are lost.
Example of a manual match
An InfoObject has a different text in the A version than in the D version. In this case the two versions have to be matched manually. When Business Content is installed, a details screen appears which asks you to specify whether the text should be transferred from the active version or from the D version.
The Match indicator is set as default in order to prevent the customer version being unintentionally overwritten. If the Content of the SAP delivery version is to be matched to the active version, you have to set the Install indicator separately.
The active version is overwritten with the delivery version if
¡        the match indicator is not set and
¡        the install indicator is set.
In other words, the delivery version is copied to the active version.
If the Install indicator is not set, the object is not copied or matched. In this case, the Match indicator has no effect.
In the context menu, two options are available:
                            a.      Merge All Below
The object in the selected hierarchy level and all objects in the lower levels of the hierarchy are selected as to Match.
                            b.      Copy All Below
The Match indicators are removed for the object in the selected hierarchy level and all objects in the lower levels of the hierarchy. If the Install indicator is also set, these objects are copied from the delivery version to the active version.
The most important properties which are taken into account when versions are matched are now listed.
When referring to InfoObjects it is important to differentiate between:
§         Characteristics
§         Time characteristics
§         Key figures and
§         Units
Valid for All InfoObjects Named Above:
Properties Matched Automatically:
Properties Matched Manually:
·        Texts
·        Description
If texts/descriptions in the delivery version do not yet exist in the active version, they are transferred.

New InfoObjects are included in compounding
·        Referenced characteristic
Reference characteristics are transferred automatically. A warning is issued.
·        Attributes / navigation attributes
New attributes are included.
If an attribute is added by the customer, the settings for this attribute are transferred (for example, F4 sequence).
·        Application components
If the entry for the active version is initial, the delivery version is used.
·        BEx display
·        Characteristic constants

·        Master data is authorization relevant (flag)
·        Export DataSource (Flag)
·        F4 query design
·        F4 query runtime
·        Check ODS object
·        Contains text tables (flag)
·        Texts are language-dependent (flag)
·        Short, medium and long texts exist (each with flag)
·        Default currency
·        GIS attribute
·        Hierarchies exist (flag)
Valid for Key Figures
Properties Matched Automatically:
Properties Matched Manually:
·        Type of key figure
·        Fixed unit
·        Fixed currency
·        Aggregation
·        Exception aggregation
Valid for Units
Properties Matched Automatically:
Properties Matched Manually:
·        See the table above (Valid for Characteristics), if these properties are also relevant for the units.
When referring to InfoProviders it is important to differentiate between:
¡        MultiProviders
¡        InfoCubes
¡        ODS Objects and
¡        InfoObjects
InfoObjects are discussed above (see the first table Valid for All Objects Named Above).
Valid for All InfoProviders Named Above:
Properties Matched Automatically:
Properties Matched Manually:
·        New InfoObjects
If InfoObjects in the delivery version do not yet exist in the active version, they are transferred.
·        Manual matching is not necessary.
Valid for MultiProviders
Properties Matched Automatically:
Properties Matched Manually:
·        New InfoProviders
If InfoProviders in the delivery version do not yet exist in the active version, they are transferred.
·        Manual matching is not necessary.
Valid for InfoCubes
Properties Matched Automatically:
Properties Matched Manually:
·        New dimensions
If dimensions in the delivery version do not yet exist in the active version, they are transferred.
·        Manual matching is not necessary.
With the InfoObject catalog object type, InfoObjects that are assigned to a catalog in the delivery version are transferred to the active version automatically. Manual matching is not necessary.
With the transfer rule object type, those objects that exist in the delivery version but are not yet contained in the active version (for example, additional attributes) are added automatically when the match is performed. Manual matching is not necessary.
With the process chain object type, those objects that exist in the delivery version but are not yet contained in the active version (for example, additional objects in the process chain) are added automatically when the match is performed. Manual matching is not necessary.
·        Active Version Available
In this column, the following display options are available:
¡        : The object is available in an active version. You decide whether you want to retain this version or reinstall the latest version of the object.
¡        Date symbol: The object is already available in an active version. However, the active version belongs to an older Content release. SAP recommends that you install the latest version.
¡        Gray symbol: An activated version of the object is available in the system. However, the object status is inactive. If an object version is activated, this indicates that all metadata for the object can be created successfully. The inactive object status indicates that the processed object is inconsistent and cannot currently be used for processing data. Transfer the object again from the SAP delivery version (D version). If this is not enough to change the object status from inactive to active the object has to be postprocessed. You find notes on postprocessing in the activation log.
Postprocessing: An inactive object status may also occur for an InfoObject if changes are made to the structure at field level. Postprocessing the object involves converting the relevant tables in accordance with the activation log.
¡        No indicator: The object is not available in an active version.
7. Make Settings in the Selection List and Install.
Make the required settings in the Install selection list:
Installation Type
Installation Type
Information
Simulate installation
The system runs a test to see whether any errors are likely to occur during the installation. However, not all errors that may occur can be identified during simulation: Some error messages can only be generated when a real A version (and not just a simulation) is available in the system. You should, therefore, only use the simulation function as a rough guide to help you identify and remove basic errors.
Install
The selected objects are installed immediately.
Install in background
The selected objects are installed in the background.
Install and transport
The selected objects are installed immediately and then written to a transport request.
SAP recommends you use the Install in background option because installing a large number of objects can take a long time. Modifying objects that are already active can take an especially long time to complete. Make sure that when you install objects in the background that the versions are not matched. It is always the delivery versions that are installed. These are not matched with any available customer versions.

What is the use of additon in up to 1 rows in SELECT statement

Hi All,
         What is the use of up to 1 rows in select statement.
for example
SELECT kostl
      FROM pa0001
      INTO y_lv_kostl UP TO 1 ROWS
      WHERE pernr EQ pernr
      AND endda GE sy-datum.
    ENDSELECT.
I'm unable to get in wat situations we hav to add up to 1 rows
please help me out...
Thanks,
santosh.

Hi,
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

Bhaskar

What is the use of Withholding tax identification number field?

Hello SAP Experts,
I posted this question earlier but had to close because of no replies from anybody. Posting it again to see if I am lucky to get some answer this time.
Can someone tell what is the use of field Withholding Tax Identification Number? Does it help with the reporting? Where does it get populated on the report if given at vendor or master record or within the withholding tax customization for company code? What is the difference between creating it in the customization for withholding tax information for company code and vendor/customer master record?
As per SAP: Withholding tax identification number
This is a number issued by the tax authorities per withholding tax type.
This number must be specified in Customizing either:
(a) As part of the withholding tax information defined for the company code, or
(b) As part of the withholding tax information defined in the customer or vendor master record.

Hi Pete,
The only thing that I could check is the content used in US:
See content of this field for US:
LFA1-STCD1 Social security number
LFA1-STCD2 Employer identification number
LFBW-WT_WTSTCD Withholding tax identification number for WT Type
In order to populate it, please kindly check the following:
The reason why you cannot fill in the field WT_WTSTCD in transaction
Fk02 however you can do it in XK02 (Change vendor centrally) can be due
to wrong customizing of the field status group.
Kindly check the following:
SPRO->
Finantial accounting -> Accounts receivable and accounts payable ->
Define screen layout per activity (vendors) -> Change Vendor(Accounting)
Company code data -> W/holding tax data, w/h tax 2 ->
FIELD Withholding tax code,w/h tax 2 will be probably just available to
display. Please, change it to optional entry.
I hope I could be of assistance.
Kind Regards,
Fernando Evangelista
