What is polling flag in process chain

Hi everbody,
What is meant by polling flag in process chain.
Points will be awared generously
Thanks in advance

polling flag is an attribute of a process chain.
With this indicator you can control the behavior of the main process when you have distributed processes. Distributed processes, such as the loading process, are characterized as having different work processes involved in specific tasks.
With the polling flag you determine whether the main process needs to be kept as long as the actual process has ended.
By selecting the indicator,
a high level of process security is guaranteed, and
external scheduling tools can be provided with the status of the distributed processes.
However, the resource use of the system is increased and a background process is more necessary

What will u do if process chain fails?

Hi gurus
What will u do if process chain fails?
Thank in advance?
Raju

Hi rajaiah
Firstly if a process chain fails, identify the process that has failed and on the context menu of the failed process you will get an option called display message where you can find the exact reason for the failure. A process chain can fail in many cases. So first try to find the error occured . For example if a process chain has failed due to invalid records then we have to edit the psa and reload the data from psa to data target (reconstruction). Based on the error message you need to take the necessary actions...
Hope this may help you.. please assign points if found helpful.

What is attribute changerun and process chain?

hi experts,
what is attribute changerun and processchain. pl explain these two with a business case.
thanks & regards
venkat

Hi Venkata,
For attribute changerun,
It's used after you change (add/delete/modify) attribute in the master data. You've to make it in order to have an effect after you modify it.
To get it :
1. tcode : RSA1.
2. Tools -> Apply Hierarchy/Attribute Change
3. tap on Info-object list button (checking what master data you've modified before).
4. tap on selection button for type of job
5. Execute.

For process chain,
Using this you can make a flow of process sequentially.
e.g.
the flow :
1. generate program YWS001
2. get the data from table zcrm001
3. load data to ods : zods_001

What would the best process chain look like for this MD data load scenario?

Hi there,
I have the following setup. SAP BW connection to external system via DBConnect (DB2 database).
We have 73 master data text data sources to load either once a week or everyday through process chain. We have not decided on the exact schedule yet.
All the master data text DataSources pull data from the SAME VIEW created on the DB2 external system:
VWDEDMASTERDATA
The structure of the view is the following:
DEDNAME
DEDNAMETYPE
DEDNAMECODE
DEDNAMEDESC
DEDNAMELONGDESC
So, everytime master data text is extracted for all the 73 objects it queries the same view over and over again VWDEDMASTERDATA. We only differentiate in the datasource on the FIELDS tab which InfoObject should DEDNAME map to and then in InfoPackage we filter on the exact object/field to query.
So essentially, every time we run InfoPackage for master data text object the external system gets queried in the following way:
SELECT * from VWDEDMASTERDATA where DEDNAME = [FIELD/InfoObject specified in InfoPackage]
So, if I have to have all 73 objects loaded, essentially the same SQL statement has to execute 73 times. In this scenario, what would be the proper process chain setup that has perfomance in mind? How should the InfoPackages be arranged, in parallel, sequentially, how many in a row, etc?
Let me know if you need more information.
thanks

They would like to send the letters to me
Depending upon how they send the letters to you and how they expect Acrobat to convert them you could be bordering on a license violation that prohibits you from using your version of Acrobat as a server-based product.
Adobe offers server based products to convert rtf files into pdf files. Some require your company to run a server, but one seams exactly what they may want. The createpdf service is run by Adobe and seems capable of doing what your company wants.

Execute process chain step based on value in a custom table

HI,
I have a requirement where i need to execute a process chain step based in the value of a field in a custom table.
e.g. If ztable-zflag = 'X' then execute next step else stop.
I am trying to use the decision between multiple alternatives process type, but i guess we can only use formulas in it.
Also, i created a custom method and called it through the badi RSAR_CONNECTOR, but the same isnt working as expected.
Would appreciate inputs from the experts.

Hi,
Thank you for your response.
I followed exactly what is written in the document. But when I execute the process chain with the Decision between Multiple Alternatives process type, it fails with an exception message.
Below is what I have done:
Below is the code that I entered in the method (Please note that ZPC_CONTROL is the table from which I need to check the value. This table contains 2 fields: Process Chain Name and Flag. My requirement is that when a particular process chain has the flag checked, then the process chain should move ahead):
Below is the GET method:
Finally, here is the formula that I have written in the Decision Between Multiple Alternatives process type:
And the event is Option 2 (which I assume will move the process chain forward if the flag is checked for the process chain ‘TEMP_TEST’)
Please note that the flag for process chain ‘TEMP_TEST’ is checked in the table ZPC_CONTROL.
Below is the error in the process chain:
Please let me know where am I going wrong here. Appreciate your help.

In process chain

Hi
whats the techinical difference between PROCESS CHAIN & MASS PROCESSING? I know about mass processing how it works creating activity and assing activity to job and scheduling the job after an event or immediate or a spcefic time... but when it come to MASS PROCSSING- RSPC. here also we need to create a varient we need to assing an varient to program varient.. but i am not able to find the difference.. can anybody make me clear..
Thanks
Deepali

Hi Deepali,
Following link gives the detailed meaning of process chains:
http://help.sap.com/saphelp_nw04/helpdata/en/8f/c08b3baaa59649e10000000a11402f/frameset.htm
Mass processing: Here individual jobs are run, we define activity for it and create a job & schedule it.
Manily job activites like forecast release, running macros, forecast creation etc.
Link below has steps for creating mass processiing jobs.
http://help.sap.com/saphelp_apo/helpdata/en/0d/429bdb38ee11d3982b0000e8a49608/frameset.htm.
Main difference in these two is that process chains is related with BI while massprocessing is not.
In APO through process chains we can trigger loading of data in the infocubes and do all the activities related with BW which we cannot do through massprocessing.

Chetana

Process Chain remote execution locks up (All Dialog Processes used up)

Hi,
We have the following task at hand. We kick in BW process chain execution via RFC from our R/3 system using the function described below. What happens is that the process chain does get kicked in the remote BW system, but it quickly locks up. System monitor says that all dialog process have been utilized. So, basically it gets stuck in the beginning of the process chain. Is there anything I can do to prevent this from happening?
Here is the function call:
This function triggers execution of process chain
(on the remote BW system)
CALL FUNCTION 'RSPC_API_CHAIN_START' DESTINATION p_rdest
    EXPORTING
      i_chain             = p_pchain
I_T_VARIABLES       =
      i_synchronous       = 'X'
I_SIMULATE          =
I_NOPLAN            =
    IMPORTING
      E_LOGID             = gv_pchain_logid
    EXCEPTIONS
     failed              = 1
     OTHERS              = 2
Thank you,

Best Practice Process Chains

Hi All,
What is the Best Practice Process chains recommended from SAP mainly for FICO related stuff.
Do anyone have the structure of FI staging ,reporting layer Process chains step by step.
Thanks in Advance
Regards
con
Edited by: con on May 21, 2009 10:01 PM

Hello con ,
two thing to follow..
1)have a Change run Step Once master data load completes for all the infoobjects which you have loaded.
The Change Run activates the master data and adapts all aggregates for newly loaded master data and hierarchies.
2)If you want to replace existing data in the DataTarget completely, first delete the data in DataTarget(also in PSA if present )and load afterwards. This will help to improve on timing parameters.
Hope this helps you!!!

Process chain start by dialog process

Hy Expert, i have a serious problem.When i schedule a process chain , it start by dialog process. What i do for start process chain by background process?
Thank's a lot.
Andrea

HI
You could do the following:
1) Create an event variant (i think it was SM63 or something like that)
2) write a short abab program that raises an event (see example)
*& Report start chain
REPORT start chain.
CALL FUNCTION 'RSSM_EVENT_RAISE'
EXPORTING
    i_eventid                    = 'your created event'
    i_eventparm                  = 'your variant'
* EXCEPTIONS
*   BAD_EVENTID                  = 1
*   EVENTID_DOES_NOT_EXIST       = 2
*   EVENTID_MISSING              = 3
*   RAISE_FAILED                 = 4
*   OTHERS                       = 5
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
3) Scedule your chain by event and activate it (you need to make it periodical to run severeal times).
4)   Scedule the program.
Hope this helps.

Minima

Isseu on Process Chains

In DP without process chains we can run the jobs, so my query is why we r useing the process chains in DP & what is the importance of process chains.

Hi Siva,
In order to automate runs in BW, processes are brought together in so-called process chains. Process chains are a sequence of processes to be performed. The are put together in a chain with the necessary dependancies (process A needs to finish before B can start) and conditions (if A and B are successful then C else send an email), and then scheduled. They usually revolve around processes related to data loading: Load, activate, roll up, compress etc.
Please take a look at this link for more info:

Cube Compression & Process Chains

Hello Friends
Few Questions as I am a beginner.
1) What is the entire concept behind Cube Compression. Why is it preferred for Delta uploads and not for full uploads.
2) What do we mean by deleting and creating indexes using process chains.
3) What is meant by the process chain "DB Statistics Refresh"? why do we need it.
Any help is appreciated. Points will be generously assigned.
Thanks and Regards
Rishi

Hello Rishi,
As you may know, an InfoCube consists of fact tables and dimension tables. The fact table hold all key figures and the corresponding dimension keys, the dimension tables refer from dimension keys to InfoObject values.
Now, there is not only one fact table but two - the F table and the E table. The difference from a technical point of view is just one InfoObject: 0REQID, the request number. This InfoObject is missing in the E table. As a result, different records in the F table could be aggregated to one record in the E table if they have the same key and were loaded by different requests.
As you may know, you can delete any request from an InfoCube by selecting the request number. And here is the disadvantage of the E table. As there is no request number you cannot delete a request from this table.
When data is loaded into an InfoCube it is stored in the F table. By compressing the InfoCube records are transmitted into the E table. Because of the disadvantage of the E table it can be defined per InfoCube if and when data has to be transmitted.
More information can be found here: http://help.sap.com/saphelp_nw70/helpdata/en/ca/aa6437e7a4080ee10000009b38f842/frameset.htm
An index is a database mechanism to accelerate the access to single records within a table. In BW indexes are used to increase the reporting speed.
Whenever data in a table is added or deleted - in our case loaded - the index has to be modified. Depending on the amount of changes in the table it could be less time consumpting to delete the index, load without an existing index and to rebuild the index afterwards. This can be done in process chains.
DB Statistics is something special for an Oracle database. As far as I know (I do not work with Oracle) it is used to optimize SQL commands which are needed for BW reports.
I hope that these explanations are helpful.
Kind regards,
Stefan
