Defining index in Dynamic parallel processing of workflow

Hi all,
I am using dynamic parallel processing feature in workflow for a particular multi-line element. But I am not able to define the index in that particular task.
Consider that i have a multi-line element "Material". For this element, I need to loop that task for that n number of records. so i am using dynamic parallel processing. Now for each workitem generated, i need to show that particular material in the workitem. I remember that we need to use index, but i couldn't recollect how it is defined.
Could anyone help me in this regard?
Thanks in advance

Nikhil,
When you use dynamic parallel processing the index is available in <b>_Wf_ParForEach_Index</b>. A reference for the line of the multi line element is automatically generated for each work item created. You can see this in the Binding Editor for the step. In your case this will be "Material()". When you drag this element to the WF to Step binding window, it will be resolved as "&Material[&_Wf_ParForEach_Index&]&. Therefore you can get the material for each WI by defining "Material" in your task container (not as multiline) and doing the appropriate binding. If you in fact need the Index in your method, you can define a container element your task with reference to Type SWC_INDEX and bind to ]_Wf_ParForEach_Index.

Problem in Dynamic Parallel processing using Blocks

Hi All,
My requirement is to have parallel approvals so I am trying to use the dynamic parallel processing through Blocks. I cant use Forks since the agents are being determined at runtime.
I am using the ParForEach block. I am sending the &agents& as a multiline container in 'Parallel Processing' tab. I have user decision in the block. Right now i am hardcoding 2 agents in the 'agents' multiline element. It is working fine..but i am getting 2 instances of the block.I understand that is because I am sending &AGENTS& in the parallel processing tab.. I just need one instance of the block going to all the users in the &AGENTS& multiline element.
Please let me know how to achieve the same. I have already searched the forum but i couldnt find anything that suits my req.
Pls help!
Regards,
Soumya

Yes that's true when ever you try to use ParForEach block then for each value entry in the table a separate workitem ID is created, i.e. a separate instance is created that paralle processing is not possible like that
Instead of that what you can do is create a fork with 3 branches and define a End Condition such that until all 3 branches are executed .
Before to the fork step determine all the agents and store them in a internal table , you can access the one internal table entry by using the index value check this [wiki|https://www.sdn.sap.com/irj/scn/wiki?path=/display/abap/accessingSingleEntryfromMulti-line+Element] to access single entry from a internal table.
For each task in the fork assgin a agent
So, as we have defined the condition that until all the three branches are executed you don't want to come out of the fork step so, it will wait until all the stpes are completed.

Dynamic parallel processing using a multiline container element

Hi All ,
I just wanted to how things work when we use "Dynamic parallel processing" for a decision step . I came across a situation wherein a Rule gets the approving user(s) and the work item should be sent to all those users . After getting an approval from all the users , the workflow should proceed or else it should terminate .
I was just wondering whether "Dynamic parallel processing" will do this job or not . I had also thought of using forks but as the number of approvers are decided at runtime , i dont think it is possible .
Any inputs ?
Edit : We are working on CRM 5.0
Thanks ,
Shounak M.

Hi Shounak,
Just do as Mike says:
use the multiline element for a subflow.
The subflow consists of your user decision, if someone rejects it, remember it (could be done by updating a small table using a method, or use an event, or what mike suggested, updating appending a table )
In the top flow, after the multiline element step determine if someone rejected it (wait for event, or reading the table).
Kind regards, Rob Dielemans

Dynamic parallel processing of the same object using asynchronous method

Hi,
Please can anyone help me?
I have to send the same DMS document to several agents for parallel processing. The number of agents is not known until runtime. Each of them should process the document and at least change the status of it. In next step I check if he has changed it.
I use dynamic parallel processing of subworkflows. Key task of this subworkflow uses standard method of object DRAW - DOCUMENT.EDIT (standard transaction CV02N) which is asynchronous. The task is finished by event DOCUMENT.CHANGED.
During the parallel processing the appropriate number of workitems is generated. However, when the agent who processes the document as first completes his workitem the event DOCUMENT.CHANGED is generated and all parallel workitems are completed, even those of other agents that were not processed yet.
Any help would be appreciated.
Thanks.
Eva Vahalova

Hi all,
The process is used to approve incoming invoices. Each scanned invoice is attached to a DMS document and than sent to one or several agents in parallel. People from several departments can approve the same invoice for instance energy or mobile phone costs. We have no HR module fully implemented. Each agent may write some remarks and has to sets the document status to either approved or rejected. This status is temporary therefore the others see the original status for approving.
The process of incoming invoices was implemented by SAP consultants in 2003 on 4.6B and now runs on our 4.7 system. Now new company was established running on a new SAP system ECC 6.0 and our accountant department and some agents will deal with invoices in both systems. Therefore, the process should appear the same or at least very similar. The majority of the old process was realized by programming while I would like to use workflow features that are available now and reduce the programming part.
As I see, I will have to choose one of the solutions that Arghadip suggested.
I wonder if there is a possibility to use asynchronous method and control the end of each work item by means of u201CComplete Work Itemu201D or u201CComplete executionu201D Conditions. I have never used them and I do not know how they work and what condition to use. Maybe program exit might be used as well. While controlling the agents I think I will have to do some programming anyway because the work item can be finished by a substitute too.
Thanks for your help.

Parallel processing in workflow with fork

Hello,
I have a case in production system. the workflow has parallel processing with fork. This fork has 2 branches as inputs.
It has 2 necessary branches with no other condition.
Does anyone know of any scenario where the workflow proceeds ahead with one branch executed even though 2 branches are mandatory.
Thanks.

Hi,
Take at look at the following 2 articles. Using the concepts outlined in them you should be able to achieve what you are trying to do.

Dynamic Parallel Processing using Rule

Hello,
I am using a User Decision within a Block (ParForEach type) step to send work-items to multiple Approvers parallelly.
For this I have created a Multi-line container LI_APPROVERS and bound &LI_APPROVERS[&_WF_PARFOREACH_INDEX&]& to &_LI_APPROVERS_LINE& in the "Parallel Processing" tab of the Block.
Now in User Decision I am using Agent as Expression = &_LI_APPROVERS_LINE&. This is working perfectly fine if I fetch the values in LI_APPROVERS via a background method before "Block" step is executed.
I want to know if we can do this using a "Rule" within the User Decision? Meaning approvers are determined by the Rule(through a FM) at the run time instead of fetching them beforehand. I created a custom Rule and tried passing it under Agents but it didn't work. I do not know what bindings need to be done and how each line will be passed to User Decision to create a work-item for each user.
Or
I should remove the Block step completely and directly use the User Decision Task with Parallel Processing option under Miscellaneous tab?
Can someone please explain how to achieve this using a Rule and exactly what bindings are required.
Thanks.

Hi Anjan,
Yes, that's exactly what I want to know. I saw your below response in one of the threads but could not understand exactly how to do it. Can you please explain it.
You have all your agents in one multiline container element in workflow.
Then you take a block step with perforeach.
Then create a custom rule which will import multiline element of agents , and a line_no. Then in the rule you populate the actor_tab with agents from that multiline contaier elemens of agent. The logic will take the agent from the multiline container[line_no].
Then you take a activity step . In agent use your custom rule usin prpoer bindin of multiline element of agents and for line_no you pass _***_line from block container. Then workitem will sent to n no of people parrallaly.
This is my current design:
Activity returns agents in LI_APPROVERS.
At Block: I have binding &LI_APPROVERS[&_WF_PARFOREACH_INDEX&]& --> &_LI_APPROVERS_LINE&
At UD: I have Agents as Expression = &_LI_APPROVERS_LINE&
I want to remove the Activity step (to get Agents in background) and replace with Rule within UD. What binding do I need from Rule to Workflow? How to get the "Line_no" from rule as you mentioned above.
Thanks for your response.

Parallel processing in quotation approval

In approval process
1) no of approvers are determined at run time i.e w.r.t discount value( 2 or 3).
2) By using FM i got the approvers in my workflow container as (app1,app2,app3) (3 container elements).
3) Here i need to trigger the workitem at a time with information in send mail step for all approvers at a time ( if 3 of them is approved the status of the quotation should change to status released.
4) if anyone is rejected among them then no status change required.
problem here is how to send the workitem to 2 or 3 approvers at a time and how do we know all of them are approved or rejected that

Hi SAUMYA,
I GOT THE DATA IN MULTILINE CONTAINER BY USING METHOD, I HAVE CREATED A METHOD WHICH GIVES POP-UP WITH APPROVE OR REJECT BUTTONS , I PUT THE MULTILINE CONTAINER ELEMENT IN Miscellaneous TAB OF APPROVAL STEP THAT USER PRESSES APPROVE RESULT ELEMENT IS '0' IF HE PRESSES REJECT VALUE '4' IS PASSED TO RESULT ELEMENT, MY REQUIREMENT IS IF ALL APPROVERS GET THE WORKITEM AT A TIME BY USING DYNAMIC PARALLEL PROCESSING , BUT HOW TO KNOW ALL OF THEM ARE APPROVED AND REJECTED , THE WORKFLOW SHOULD EXECUTE NEXT STEP TILL ALL OF THEM ARE EITHER APPROVED OR REJECTED. IF ANY ONE OF THEM IS REJECTED THEN WORKFLOW WILL BE COMPLETED AT THAT POINT.

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

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

Dynamic Parallel Approval for HCM Process and Forms

Hi everyone,
I have a scenario where I need to use the "Dynamic Parallel Approval" (or to keep it simple, initially I tried using the "Parallel Approval" wizard)for a workflow used in the HCM Process and Forms.
The standard task for approval in process and forms is TS17900101. I have mentioned a multiline container in the Miscellaneous tab of this task. However,I was unable to use this task in the wizard. There are no results attahced to this task unlike any other standard approval task (like TS30200147). I need to use the task TS17900101 in the workflow assigned to process and forms, but not sure how to handle this scenario (parallel approval).
If this is not the right way of doing it, Is there any workaround for "Parallel Approval" in HCM Process and Forms.
Could anybody throw some light around this area.
Thanks for your help.
- MM

Thanks Anuj. But I believe, the container element that I add in the miscellaneous tab does not necessarily have to be used in the agent assignment. The multiline container is just to instantiate the workitem 'n' number of times. Correct me if I am wrong.
My concern is that I was unable to use this approval task (TS17900101) in the workflow wizard for dynamic paralle/parallel approval.
Arghadip - Thanks for your suggestion. I have seen some your nice contributions in the WF forum.
I actually tried using the 'Blocks'. But this is what I ran into. When I send multiple approval requests (say 3), if one person has approved it and the second has rejected it,I need to take out the workitem from the third person's list (because it has been rejected by someone in the group). I am not sure if this is possible using Blocks. And in my case the third person is still having the workitem, but gets a dump/error when he tries to open it.
Also, if any one has rejected the request, I do not have to wait for the rest to take any action on the workitem and proceed further. But I guess in 'Blocks' it will not let you go out unless every workitem has been processed.
To summarize,here's what I need - I need to come out of the block for two conditions. One, if everyone has approved, comeout of the block with an apprval flag. Two, if anyone has rejected (even if some have not processed their workitem), delete the workitems from others inbox and come out of the block with a rejection flag.
So, any kind of input or suggestions on how this could be handled would be highly appreciated.
Thanks
MM

Parallel workflow in Process controlled workflow

Dear experts,
could you please answer -
is it possible to use parallel worklow in the process controlled workflow?
for example, there is a requirement that all the department managers should approve the RFx document or contract.
Is it possible to simulate this process using the process controlled workflow in SRM 7.0?
It seems, that in the standard it is possible only via sequential approval - i.e. the first manager approves
the document, then it goes to the second etc.
Or all the managers receive the work item, but only one manager in fact approves it.
Both variants are not suitable.
Maybe there is another way to simulate the parallel worklow process?
There is an option called decision sets, but it can be used for shopping cart only.
Thanks a lot in advance,
Andrey Averin.

Hi,
Yes- This is possible through Process controlled workflow. I am doing a smiler kind of workflow development. like category approvers .. Category approval will split by category...but you have to build the logic such a way that read all the items and send to all the approvers.. But now i have noticed that even through all approvers will receive parallel workitem but Approver A can't open his/her workitem if Approver B is in the process of approve/reject the workitem( Meaning when he double click the workitem in detail) then Approver A will receive a Error pop up message saying that Approver B is working on this document.

How to define "leading" random number in Infoset fpr parallel processing

Hello,
in Bankanalyzer we use an Infoset which consists of a selection across 4 ODS tables to gather data.
No matter which PACKNO fields we check or uncheck in the infoset definition screen (TA RSISET), the parallel frameworks always selects the same PACKNO field from one ODS table.
Unfortunately, the table that is selected by the framework is not suitable, because our
"leading" ODS table which holds most of our selection criteria is another one.
How to "convince" the parallel framework to select our leading table for the specification
of the PACKNO in addition (this would be times 20 faster due to better select options).
We even tried to assign "alternate characteristics" to the packnos we do not liek to use,
but it seems that note 999101 just fixes this for non-system-fields.
But for the random number a diffrent form routine is used in /BA1/LF3_OBJ_INDEX_READF01
fill_range_random instead of fill_range.
Has anyone managed to assign the PACKNO of his choice to the infoset selection?
How?
Thanks in advance
Volker

Well, it is a bit more complicated
ODS one, that the parallel framework selects for being the one to deliver the PACKNO
is about equal in size (~120GB each) to ODS two which has two significant field which cuts down the
amount of data to be retreived.
Currently we execute the generated SQL in the best possible manner (by faking some stats )
The problem is, that I'd like to have a Statement that has the PACKNO in the very same table.
PACKNO is a generated random number esp. to be used for parallel processing.
The job starts about 100 slaves
Each slave gets a packet to be processed from the framework, which is internaly represented
by a BETWEEN clause on this PACKNO. This is joined against ODS2 and then the selective fields
can be compared resultin in 90% of the already fetched rowes can be discarded.
Basicly it goes like
select ...
from
ods1 T_00,
ods2 T_01,
ods3 T_02,
ods4 T_03
where
... some key equivalence join-conditions ...
AND T_00.PACKNO BETWEEN '000000' and '000050' -- very selective on T_00
AND T_01.TYPE = '202' -- selective Value 10% on second table
I'd trying to change this to
AND T_01.PACKNO BETWEEN '000000' and '000050'
AND T_01.TYPE = '202' -- selective Value 10%
so I can use a combined Index on T_01 (TYPE;PACKNO)
This would be times 10 more selective on the driving table and due to the fact,
that T_00 would be joined for just the rows I need, about a calculated time 20-30 faster.
It really boosts when I do this in sqlplus
Hope this clearyfies a bit.
Problem is, that I can not change the code either for doing the
build of the packets or the one that executes the application.
I need to change the Inofset, so that the framework decides to build
proper SQL with T_01.PACKNO instead of T_00.PACKNO.
Thanks a lot
Volker

Parallel process define for batch job

Hi,
I would like to run a batch job with a few processes run parallel together. May I know where can i define it ? T-code ?
Regards
Lauran

Hi Lauren,
First of all there is no transaction code as such.
First of all the report that needs to be run in background should enable you to do parrallel processing. For that code has to be written accordingly.
Check this link:
http://help.sap.com/saphelp_nw2004s/helpdata/en/fa/096e92543b11d1898e0000e8322d00/content.htm
It gives details of function modules needed for this purpose.
After this you need to create a variant for the report and schedule it to run in background using either SE38 (dirrectly) or by creating a job explicitily- SM36.
A standard report that has parallel processing feature available is RBDAPP01.
Also check transactions like BD18. They also make use of parallel processing.
Regards.

Parallel processing end condition problem

Hi,
i use a block with parallel processing for each row (parforeach). In every branch i create a workitem where a user has to input something. This is stored in my field status.
Now i want that if the status is 'X' all branches will be closed like it would be in a fork.
I entered the end condition &status& = X
But the end condition of parallel processing doesn't work. I tested it and it works but into the workflow the branches won't be ended.
Does someone has a solution or can explain me the problem?
Thx

Hi,
The dynamic parallelism using 'parforeach' is not the same as fork with multiple branches with number of required branches to end the fork !! Its like this, when you use dynamic parallelism , for each index of your multiline container element used for parallelism, the sub-workflow ( or the associated Task having dynamic parallelism) will be called parallely and each branch ( parallely called sub workflow or task ) is independent now having no relation ( by default ) and workflow will not continue to next step until unless all these branches are completed.
However, to solve your probelm i suggest the following
1. How are you handling the process in each branch, is it through a sub workflow? if yes, in your sub workflow you can create a fork parallel to your normal process. In that fork, create a 'Wait for Event' step and wait for a new custom event ( for this you have to define a new custom event on your BO) . Put the necessary branches required as 1 and Join this branch to end of this sub-workflow. and
2. Whenever your requirement to end all the branches is fulfilled ( say in your case status=X) raise this new custom event using Create Event and this will be captured by 'Wait Event' step in the fork of your sub-workflow and it will end that sub workflow ( meaning, your branch is ended now) .Make sure that you pass the BO Object Instance to your sub-workflow through binding from your main workflow. !!
Hope this helps you !!
Regards

Notes on the parallel_clause
If table contains any columns of LOB or user-defined object type, this statement as well as subsequent INSERT, UPDATE, or DELETE operations on table are executed serially without notification. Subsequent queries, however, will be executed in parallel.
For partitioned index-organized tables, CREATE TABLE ... AS SELECT is executed serially, as are subsequent DML operations. Subsequent queries, however, will be executed in parallel.
A parallel hint overrides the effect of the parallel_clause.
DML statements and CREATE TABLE ... AS SELECT statements that reference remote objects can run in parallel. However, the "remote object" must really be on a remote database. The reference cannot loop back to an object on the local database (for example, by way of a synonym on the remote database pointing back to an object on the local database).
참고로, 테이블 생성시에 degree of parallelism 를 사용하는 건
바람직하지 않고, 필요한 sql문에 hint 를 사용하는 것을 권장합니다.
