Difference between Replication and Activation of Data Sources

Hi,
I would like to know what exactly happens when data sources are replicated and when data souces are activated
Regards,
Visali.G.

Once you make the replicate of DS at BW, what ever the struc. for that DS would be regenarated, and accordingly your extraction and setup table struc. would get updated by the latest changes made in the DS.
At the BW side all corresponding communication and transfer structure and PSA structure would also get generated according to the DS struct. per R/3
Need of Replication in other terms we can say
Replication needs to be done is each time you save you datasource in R/3. This causes the timestamp of the datasource to be changed and hence the timestamp of the datasource in R/3 and BW are not in sync. Replication would make the timestamp in sync in both R/3 and BW.
Hence you would notice the error "Timestamp error" when you do not replicate the datasource after changing it.
Activating the data source, activating the structure and make available the dat source to use.

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Difference between passive and active data connection mode for FTP

Hi,
Does any body have the idea of passive and active data connection mode for the transport protocol FTP.
I have one server with FTP, I have to pick the data from this FTP to XI.
What is the difference between active and passive data connection? Does XI supports both the connections?
Thanks & Regards
Katta Mohan Reddy

Hi
According to SAP Note - 821267
Q: Does the File Adapter support active data connections when connecting to an FTP server?
A: Up to and including SP14, the File Adapter exclusively uses passive data connections. Starting with SP15, active connections will be available.

Difference Between 0CREATED_ON and Today's date

Hi Experts,
I am new to BW and I have to accomplish the following requirement.
We have a characteristic 0CREATED_ON and when the report is run we need to calculate the difference between today's date and 0CREATED_ON. Can you please advice on the best possible way to achieve the same. If it could be broken into the logical steps, it would be a great help!!
Thanks for the help in advance.
Regards
PG

Hi Piyush,
When you create the query make sure that characteristic Created on is in rows . Select all other characteristics and keyfigures in your query as per your requirement. Now
Step 1. Create a formula variable by replacement path on Created_on lets say FVCRON .
Step2. Activate the business content variable "Formula Variable for Current Calendar Day - 0F_ADAY " . If it is already active you should be able to see in your formula variable list.
Step3. create a Calculated Keyfigure 0F_ADAY - FVCRON .
If you need individual steps on how to create formula variable or to activate business content variable or how to create a variable using customer exit let me know.

FTPS settings Difference between control and control with data

Hi guys,
Just a very quick question please. When doing FTPS there are two options
1) control
2) control with data
Can anyone explain what's the difference between the two?
regards

Hi,
FTPS (FTP Using SSL/TLS) for Control Connection
The FTP control connection is protected using TLS/SSL (Transport Layer Security/Secure Sockets Layer). File transfer is unencrypted.
FTPS (FTP Using SSL/TLS) for Control and Data Connection
All communication with the FTP server is encrypted and uses TLS/SSL.

Difference between installing and activating business content

Hi,
I am new to BW, would like to know some info
1) What is the difference between install busines content and activate business content, When i should do what
2) When a business content is installed do i need to go to modelling tab and activate it as well.
3) if a business content is installed would all other related objects get activated automaically like its update rules, transfer rules etc.
Thanks
Akila.R

Hi Ramachandran,
Good question,
This issue can be adressed with the "Match x or copy" option in the Business content activation screen.
Here with this option you can decide wether you need to overwrite the earlier content or not.
Follow the link for further explanation on "Match x or copy".

What is the diff between replication and streams

Hello,
Can some one tell me the difference between replication and Oracle streams, When I look into the documentation, it says to use the Oracle EM Console to setup the Replication.But I am not sure how do I download the Oracle EM Console.
Thanks for all who replies for this.

Replication is a Neolithic, perhaps Paleolithic, technology that slightly improved replication over what we did back in the days when we lived in caves and spoke only using grunts and hand motions.
Replication is hard to set up, hard to maintain, and essentially guaranteed to give you full-time employment and loss of hair due to gaps created by transactions that do not replicate correctly and network issues.
Streams is far from perfect but is vastly superior in terms of flexibility, gap resolution, and performance.
When looking at Streams also look at Change Data Capture (CDC). If CDC will do the job don't do Streams directly. Use the simplified API.

Difference between sapscripts and BDCs

what is the difference between sapscripts and BDCs

BDC for data communication between sap to non sap(vice-versa)
where scripts is a business layout(we create)
bdc help
They are the only 3 methods mostly we use in BDC.
Call _Dialog is outdated. it is there in the intial stages of SAP.
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
For BDC:

Different between Passive and Active SFP+ cable

Hey,
We'd like to know what is the different between Cisco SFP+ copper passive twinax cable and active cable?
We test some Siemon passive SFP+ 7m and 10m copper cables and these cables passed our lab test ( link between nexus 5548 and FEX link).
Is that means we can using Siemon to take over Cisco because of same function and lower cost?
Thanks.

Greetings,
The following page explains in detail the difference between passive and active copper assemblies - http://www.scientificcomputing.com/High-speed-Copper-Interconnects-Address-Critical-HPCHurdles.aspx.
You can use any Cisco Twinax cables between a Nexus 5548 switch and Fabric Extender (note that Nexus 7000 switches do not support all Twinax cables). The 7 and 10m cables use an active design while the shorter cables are passive.
Non-Cisco transceivers are not compatability validated and may not be supported by TAC if you encounter any issues (Warranty Guideline http://www.cisco.com/en/US/prod/prod_warranty09186a00800b5594.html). We recommend always using official Cisco components.
Hope this helps,

Difference between 0FI_AP_30 and 0FI_AP_4 Data source

HI,
What is the difference between 0FI_AP_30 and 0FI_AP_4 Data source.
Thanks in advance

Hi,
In addition to above differences. Below is the functional difference between 0FI_AP_30 & 0FI_AP_4:
0FI_AP_4 gives you accounts payable line items in your report. Here GL account shows the balances of particular types of vendors/payables to which that particular GL account is been assigned.
And If subledger is activated in ECC, then by using 0FI_AP_30 you can get the break up of that particular GL balance according to vendors.
To make use of datasource 0FI_AP_30, subledger accounting must be activated in ECC.

Difference bw the data staging of generic and appli specefic data sources

Hi,
Can anyone tell the difference between data staging of generic and appl specific data sources. Like we know that LO data stage in queued delta, update queue and BW delta queue, i want to know actually where the generic data stages before it is loaded into BW.
Thanks.

Generic data sources are based on either a DB table/view, a function module or an ABAP query. So normally the data stages in the corresponding DB tables or you calculate it at extraction time. There is no update queue like in LO.

Differences between archiving and inactivating a qualitative lookup within the Data Admin toolkit.

Hi,
Can you please let me know what could be the difference between archiving and Inactivating the Qualitative Lookup in Data Admin Tool Kit.
Thanks,
Rohini M

When you inactive or archive something it is no longer available for selection.   The difference between inactive and archive is that inactive items will still appear available for searching purposes while archive items will not.
So lets say you have the following:
List A
   - Item 1
   - Item 2
List Items
If you were to inactivate Item 1, end users would no longer see it available for selection when using the qualitative extended attribute. However when they search for specs based on the extended attribute they would still be able to select Item 1 so they could find objects that used that value. If you were to archive Item 1, end users should no longer see it available for selection anywhere - including searching.
Lists
If you were to inactive or archive the entire List A, you would no longer see it available for selection when setting up qualitative lookup extended attributes.   I don't think there is anywhere you can search for extended attributes by lookup list currently out of the box so these would act similar. If there was a place to search for extended attributes by lookup list then it would follow the same rules as above.

Activity System status: differences between u0093Openu0094 and u0093In processu0094 status

Dear Experts,
Whats the difference between Open and In process system status? In help.sap.com it: There are four system statuses that represent the life cycle of the business transaction:
Open: has been recently created and not yet processed (for example, contract from the Internet)
In process: administrator is clearing up questions
But, how does the system assumes the In Process status ?? Ive tested business activities creation with different employees assigned and, when editing and saving the business activities with these BPs the system status does not change.
However, in other unknown situations the status system is changed to in Process.
Any ideas about the meaning of the In Process status? And when the business activity switches to that?
Thanks in advance,
Joao

Hi,
These four system statuses that represent the life cycle of the business transaction:
·        Open: has been recently created and not yet processed (for example, contract from the Internet)
·        In process: administrator is clearing up questions
·        Released: contract is complete and legal. Follow-up processes can be started (printing, billing, distribution, releases and so on)
·        Completed: All actions directly linked to contract are completed
·        Closed: all actions indirectly linked to the contract are closed (for example, from R/3: batch run to actual costs)
Each status having its own control at the configuration level. If you observe the following process you may understand the importance of various statuses.
For example in any transaction by default status would be Open. Once the transaction opened by the respective responsible person he will change the status as In Process, Once the assigned task is completed he will change the status as Completed.
Please notice the configuration settings in the following navigation path:
SPRO->IMG->CRM->Transactions->Basic Functions->Status Management-> Change Status Profile for User Status->Select Quotation->Double click on the different status. You can observe the difference.
Hope I convinced.
Best Regards,
Johnny.

What is the difference between olap and data warehouse..?

Hi All,
Is their any difference between olap and data warehouse..? Please let me know your knowledge about these. Thank you..
------------------------------------------------------------------------ Please mark it as complete, if you get the solution with this reply. TQ.

A data warehouse is a database containing data that usually represents the business history of an organization. This historical data is used for analysis. Data in a data warehouse is organized to support analysis rather than to process real-time transactions
as in online transaction processing systems (OLTP).
OLAP technology enables data warehouses to be used effectively for online analysis, providing rapid responses to iterative complex analytical queries. OLAP's multidimensional data model and data aggregation techniques organize and summarize large amounts
of data so it can be evaluated quickly using online analysis and graphical tools.

Media Foundation Source or H264 / AC3 differences between Windows and Phone 8?

I've got a working Matroska (MKV) Media Foundation Source for a Windows Store app (PC x86). It will play several different matroska files that contain H264 encoded video and AC3-encoded audio. It even has seek support. I've written the app
as a HTML/typescript Universal app with the MF Source as a C++ dll.
The problem is that the same code will not work on Windows Phone 8. I can play videos that don't require the external MF Source (i.e. MP4 files and AVI files) just fine on both platforms through my app, but the same MKV videos that played on an x86
PC will not play on Windows Phone 8 (Lumia 920).
I looked at the specs for the Snapdragon processor and it should be able to support both H264 at 720p resolution and AC3 (2-channel only). So I don't know what else I need to do to get this to work on WP8. The audio I'm trying to play is actually
6-channel, so that made me wonder if it was failing because WP8 supports 2-channel max, but I would have thought the audio just wouldn't work and the video would play normally.
Does anyone have any suggestions?
*edit* - just to be more specific, I can parse the file and create the presentation descriptor without errors. But when I finish opening the file and call the event for that, nothing else happens. What is weird is that the javascript video player
never throws the "canplay" event, nor does it throw the "error" event.
Lee McPherson

Thanks, not a bad suggestion to try.
On my Windows machine, I tried to get the MediaEncodingProfile via the createFromFileAsyc method. With a known file type, it outputs all properties of the video and audio streams (bitrate, etc). With an MKV file (container file with H264 video
and AC3 audio), I only get the type and subtype properties. Everything else is zero or null. This is because in my MFSource, I only set the type and subtype. This still allows the video to play on my windows machine. I assume the
built-in MFTransform for H264 video-to-uncompressed video parses the stream to get the relevant information. Likewise for audio.
On Windows Phone, when querying the file's MediaEncodingProfile, I get the same result. This is telling me that my MFSource will parse the file properly and set the subtypes for video and audio correctly. Everything else is still null or zero.
However, the file does not play. There is no returned event to the video element that it even *can* play.
Perhaps, I need to fill in the video and audio stream properties on the Windows Phone version. I really don't want to because that would mean having to parse some of the underlying video and audio streams themselves, not just parsing the container
information. (More work!) But this is what I mean when I ask about the differences between Windows and Windows Phone... perhaps the WP8.1 & Windows MFTransforms are different?
*EDIT* - I do get a JavaScript Console error that I didn't notice before: AUDIO/VIDEO: unknown MIME type. (VS error code: MEDIA12899)
