Parallel processing in MRP

CAn anybody tell me the use of parallel processing in MD01 screen...
SAP help tells the following..
But I cant understand that..
PLease help me get a clarification.

Dear
The parallel processing use in total planning run in MD01 or MD40 thats meas planning run for number of plant at atime. By using parallel processing procedures, you can significantly improve the total planning run. The parallel processing procedures can either run on several servers or in several sessions. So we define this setting in OMIQ.
Scope of planning in OMIZ here we combine the number of plant/ MRP are for total palnning run which use in MD01 to run MRP for all plant at same time.
So if you want to run the MRP for all palnt or MRP Area as total planning run then you need to define scope of planning and parallel processing to improve the system performance and if you don't define it then also you can excetue the MRP.
Summery is :
1) If you want to run MRP viw MD 01 online you require scope of planning.
Reason:- With scope of planning only you can combine no of plant / MRP area.etc.,
If you want to run MRP in back ground this is not required.
2) Always parallel processing will improve the system speed by acessing data base layer with multiple application layer.
setup : go to SPRO>material management>Consumption based planning-->Define parallel processing in MRP.
Refer : the parallel process for mrp.
Hope this will be useful

The parallel process for mrp.

hi exports
we plan to do the scope of planning for the total planning as a background job.
while doing that system ask for the parallal processing for mrp
what is customize step and procedure to do the parallel process for mrp.

Dear Raj,
With the help of parallel processing procedures, you can significantly improve the runtime of the total planning run.
To process in parallel, you can either select various sessions on the application server or various servers.
Parallel processing runs according to packages using the low-level code logic:
The work package, with a fixed number of materials that are internally defined in the program, is distributed over the individual servers/sessions. Once a server/session has finished processing a package, it starts processing the next package.
If a low-level code is being planned, the servers/sessions that have finished must wait until the last server/session has finished its package to avoid inconsistencies. Then the next low-level code is processed per packages.
The parallel processing procedure is switched on in the initial screen of total planning.
Activities
Define the application server with the number of sessions that can be used:
If you want to define various servers for parallel processing, enter the server with the number of sessions.
If you only want to use one server, but several sessions, enter the application server and the appropriate number of sessions.
Further notes
Parallel processing shortens the time required for calculation, however, it cannot shorten the database time as the system still only operates using one database.
The Customizing Transaction is OMIQ

Parallel Processing Error

Hi Gurus,
While running MRP at Plant level (MD01), System throws error as
" <b>Check the destinations for parallel MRP</b>" in Quality Server.
As we have done same setting in DEV & it's allowing to Run MRP.
Give comment on it.
Thanx in Advance.

Hi..,
go to SPRO>material management>Consumption based planning-->Define parallel processing in MRP.
their give the name and no. of sessions like 4 or 5.
your problem will be solved.

Group data locked error for MM01 using parallel processing

Hello gurus,
I am using Call txn method (MM01) Parallel Processing method ( around 9 threads ). The Materials are getting locked around 10 percent sometimes.
This is happening randomly ..one day i dont have any locking errors ..next day i have ...Any ideas why this could be..any prereq i need to check before executing the parallel processing..
Thank you in advance..
sasidhar p

Hi Sasidhar
I guess you are either extending the Sales Data or MRP Data. Just make sure that you are processing these transactions in a linear form for a single material. We can use parallel processing for different materials but for a single material if we go for parallel processing we can definetely expect the Lock Objects error.
Kind Regards

Parallel Processing : Unable to capture return results using RECIEVE

Hi,
I am using parallel processing in one of my program and it is working fine but I am not able to collect return results using RECIEVE statement.
I am using
CALL FUNCTION <FUNCTION MODULE NAME>
STARTING NEW TASK TASKNAME DESTINATION IN GROUP DEFAULT_GROUP
PERFORMING RETURN_INFO ON END OF TASK
and then in subroutine RETURN_INFO I am using RECEIVE statement.
My RFC is calling another BAPI and doing explicit commit as well.
Any pointer will be of great help.
Regards,
Deepak Bhalla
Message was edited by: Deepak Bhalla
I used the wait command after rfc call and it worked additionally I have used Message switch in Receive statement because RECIEVE statement was returing sy-subrc 2.

Not sure what's going on here. Possibly a corrupt drive? Or the target drive is full?

Parallel processing of mass data : sy-subrc value is not changed

Hi,
I have used the Parallel processing of mass data using the "Start New Task" . In my function module I am handling the exceptions and finally raise the application specific old exception to be handled in my main report program. Somehow the sy-subrc is not getting changed and always returns 0 even if the expection is raised.
Can anyone help me about the same.
Thanks & Regards,

Hi Silky,
I've build a block of code to explain this.
DATA: ls_edgar TYPE zedgar,
        l_task(40).
DELETE FROM zedgar.
COMMIT WORK.
l_task = 'task1'.
ls_edgar-matnr = '123'.
ls_edgar-text = 'qwe'.
CALL FUNCTION 'Z_EDGAR_COMMIT_ROLLBACK' STARTING NEW TASK l_task PERFORMING f_go ON END OF TASK
    EXPORTING
      line = ls_edgar.
l_task = 'task2'.
ls_edgar-matnr = 'abc'.
ls_edgar-text = 'def'.
CALL FUNCTION 'Z_EDGAR_COMMIT_ROLLBACK' STARTING NEW TASK l_task PERFORMING f_go ON END OF TASK
    EXPORTING
      line = ls_edgar.
l_task = 'task3'.
ls_edgar-matnr = '456'.
ls_edgar-text = 'xyz'.
CALL FUNCTION 'Z_EDGAR_COMMIT_ROLLBACK' STARTING NEW TASK l_task PERFORMING f_go ON END OF TASK
    EXPORTING
      line = ls_edgar.
*&      Form f_go
FORM f_go USING p_c TYPE ctype.
RECEIVE RESULTS FROM FUNCTION 'Z_EDGAR_COMMIT_ROLLBACK' EXCEPTIONS err = 2.
IF sy-subrc = 2.
*this won't affect the LUW of the received function
    ROLLBACK WORK.
ELSE.
*this won't affect the LUW of the received function
    COMMIT WORK.
ENDIF.
ENDFORM.                    "f_go
and the function is:
FUNCTION z_edgar_commit_rollback.
*"*"Interface local:
*" IMPORTING
*"     VALUE(LINE) TYPE ZEDGAR
*" EXCEPTIONS
*"      ERR
MODIFY zedgar FROM line.
IF line-matnr CP 'a*'.
*comment raise or rollback/commit to test
*    RAISE err.
    ROLLBACK WORK.
ELSE.
    COMMIT WORK.
ENDIF.
ENDFUNCTION.
ok.
In your main program you have a Logical Unit of Work (LUW), witch consists of an application transaction and is associated with a database transaction. Once you start a new task, your creating an independent LUW, with it's own database transaction.
So if you do a commit or rollback in your function the effect is only on the records your processing in the function.
There is a way to capture the event when this LUW concludes in the main LUW. That is the PERFORMING whatever ON END OF TASK. In there you can get the result of the function but you cannot commit or rollback the LUW from the function since it already have implicitly happened at the conclusion of the funtion. You can test it by correctly comment the code I've supplied.
So, if you want to rollback the LUW of the function you better do it inside it.
I don't think it matches exactly your question, maybe it lead you on the right track. Give me more details if it doesn't.
Hope it helps,
Edgar

Parallel Processing and Capacity Utilization

Dear Guru's,
We have following requirement.
Workcenter A Capacity is 1000.   (Operations are similar)
Workcenter B Capacity is 1500.   (Operations are similar)
Workcenter C Capacity is 2000.   (Operations are similar)
1) For Product A: Production Order Qty is 4500. Can we use all workcenter as a parallel processing through Routing.
2) For Product B: Production Order Qty is 2500. Can we use only W/C A and B as a parallel processing through Routing.
If yes, plz explain how?

May be you can create a virtual WC VWCA=ABC (connected with a hierarchy with transaction CR22) and another VWCB=A+B and route your products to each VWC

Parallel processing open items (FPO4P)

Hello,
I have a question about transaction FPO4p (parallel processing of open items).
When saving the parameters the following message always appears : "Report cannot be evaluated in parallel". The information details tells that when you use a specific parallel processing object, you also need to use that field to sort on.
I my case I use the object GPART for parallel processing (see tab technical settings). In the tab output control I selected a line layout which is sorted by business partner (GPART). Furthermore no selection options are used.
Does anyone know why the transaction cannot save the parameters and shows the error message specified above. I really don't know what goes wrong.
Thank you in advance.

How to do parallel processing with dynamic internal table

Hi All,
I need to implement parallel processing that involves dynamically created internal tables. I tried doing so using RFC function modules (using starting new task and other such methods) but didn't get success this requires RFC enabled function modules and at the same time RFC enabled function modules do not allow generic data type (STANDARD TABLE) which is needed for passing dynamic internal tables. My exact requirement is as follows:
1. I've large chunk of data in two internal tables, one of them is formed dynamically and hence it's structure is not known at the time of coding.
2. This data has to be processed together to generate another internal table, whose structure is pre-defined. But this data processing is taking very long time as the number of records are close to a million.
3. I need to divide the dynamic internal table into (say) 1000 records each and pass to a function module and submit it to run in another task. Many such tasks will be executed in parallel.
4. The function module running in parallel can insert the processed data into a database table and the main program can access it from there.
Unfortunately, due to the limitation of not allowing generic data types in RFC, I'm unable to do this. Does anyone has any idea how to implement parallel processing using dynamic internal tables in these type of conditions.
Any help will be highly appreciated.
Thanks and regards,
Ashin

How to achieve parallel processing in a single request?

Hi all,
I have a method in a Session EJB that will perform some business logic before it returns an answer to the client. The logic it will perform is to collect data from the applications database and two external systems, before sending all data to a third external system to get a response and send it back to the client. Each external system is quite slow so I would like to do all the collecting of data concurrent, parallel processing. How should I handle this? I'm not allowed to create my own threads in EJB's. Can I use MDB in some way? To the calling client this should be a synchronous call...
Greatfull for any suggestions
Cheers
Anders =)

Usually, the request is received by a component located in the web container, such as by an HTTP request (including Web Services). This component is able to start threads to allow parallel processing. Now, if for some reason the request arrives directly at EJB level and that you cannot move its receiver to web component, I think JMS is not a viable solution because you will switch to asynchronous processing and you have no way to make your EJB wait for the responses while preserving the client request (waiting implies programmatic life cycle management, which is forbidden in EJB container). Maybe a resource adapter (JCA) can bring a solution. A resource adapter acts as a datasource (a datasource is a specialization of a resource adapter) and thus it is a logical way to implement an adapter to an external, eventually non-J2EE, resource, as the name implies :) But I don't have enough knowledge in JCA to be sure of this.
Hope it helps.

FORK is Not happening Parallel processing- It's working sequential

Hi,
   we are into PI 7.O and SP 13.
   I am trying to test Parallel processing using Fork step. (With Two branches)
My problem is sxm_moni both branches are not executed simultenously and it's executing one after the other.
Did any body done in XI parallel processing using BPM...both calls has to finish at the same time. I mean first call 10 min and second call aslo has to finish first 10 min ..not other 10 min.
I heard this problem from XI 3.0 and PI 7.O. But PI 7.1 did any body test the Parallel processing using Fork step.
   Pls help me is this issue will resolve if I go to PI 7.1.
Regards,
Venu.

Hi Henrique,
they would not necessarily start at the same time but shouldnt also be queued - Customer expecting the response within a 17 sec or 20 Sec but coming response 34 sec will not ok for the customer..tomorrow need add some more target again 17 sec will take...How PI can handle the Multi threading they are checking...I am not sure this problem fixed in PI 7.1 or not.
there're # of connection restrictions in your system? Check that - Where can I check connections restrictions...If you know pls through some light on this.
Also, how's your BPM transactional behavior (did you flag the create new transaction steps)?
- I did not checked the flag for create new transaction step..once my server is up I can check the flag and I can test.
Regards,
Venu.

Parallel Processing in CRM 5.0 for Customer download

Hi
I was referring to OSS note 350176 for implementing parallel processing. I wanted to achieve parallel processing for request loads for Customer download.
Is it possible to achieve it by setting the parameter CRM_MAX_QUEUE_NUMBER_INITIAL in CRMPAROLTP or it can be achieved only through implementing exits?
Thanks for your help in anticipation.
Regards
Karthik

HI
Karthik in Parralllel processing first you need to set up diffent filters for diffrent types of data basic or business data, customizing and condition data R3 AC1, R3 AC4, R3 Ac5 separately then start down loading the objects to CRM , remaning objects left over can be bypassed , then set the Satus of down loading Yellow red and Blue depends up on percentage of down load y for more than 100% R for more than 75%, B for less than 50%

Using BAPI_PO_CREATE1 in parallel processing

Hi experts,
I am using BAPI_PO_CRATE1 in parallel processing to create multiple Purchase Orders. The Programs is creating only one PO (the Ist one) however it should create multiple PO as per the program and data.
For rest of the data it is returning error message saying "No instance of object type PurchaseOrder has been created".
Please suggest how can I fix this issue.
Points are sure.
Thanks & Regards.

Without looking at some poriton of the code around this call and your parallel processing logic, it will be difficult to say.

BI 7.0 parallel processing of queries in a web application

Hi,
I'm currently having problems with a web application / web template with 10 data providers (different queries). When executing the web application the 10 queries are executed sequentially. Since each query takes about 30 sec., the complete execution time exceeds 300 seconds which is not satisfactory.
Is there any way to enable parallel processing?
Thanx in advance,
Patrick
