Process Chains Overlapping

Hi,
We are on BW 3.1C and have different process chains for our US Hourly Refresh and UK Process Chains which runs every night. We are using different Process variants for each chain. Our Hourly refresh chain is sometimes overlapping with nightly chain. It is appearing on the same screen and it is causing issues. I have deleted the entire chain and recreated with different process variant still the problem is same. The problem is not reproducable, it is happening sometimes.
Any help will be greatly appreciated.
Regards
Nag

Hi,
If you know the exact/approx time, when those 2 cahins are overlapping ?? If you know the exact time, then set a wait on your UK process chiain for the duration of your US ProcessChain run time.
You can right click on Start process and set waiting time.
Hope this helps.

Delete Overlapping Request in Process Chain

Hi,
Im working on Process chain to upload data from four source cubes to one target cube. Process chain has been configured as after the Data Transfer Processs successful execution, system looks for overlapping data requests and deletes them. Chain seems doing the required functionality but the only thing going wrong is when it comes to deletion of overlapping requests, it randomly delete few and leave others. The status of undeleted ones switched to erroneous and this prevents newly generated data requests available for reporting.
Regards,
Shabbar

Hi,
Thanks for your replies. For deletion Im using Same or More Comprehensive option because I just want to delete the corresponding request with the same selection.
There are four requests need to be created with every run and it should delete the corresponding four. But I dont know whats going wrong, why and how it picks up a few out of four for deletion and left the rest with erroneous status.
Hope this would make the problem statement clear, if you require any further information, please let me know.

Shabbar

"Delete Overlapping Requests from InfoCube" in a Process Chain

Dear all,
I encountered a problem when I building the process chain in BW 3.0.
In a process chain, I schedule daily an InfoPackage to load data to an InfoCube and then delete the previously loaded data by the same InfoPacckage from the InfoCube.
For example, I have 2 InfoPacakge, A and B, and schedule to load data to InfoCube C. In the process chain, I scheduled daily the following tasks in sequence:
- Delete index in InfoCube C
- Load data through InfoPackage A to InfoCube C
- Delete duplicated request previously loaded through InfoPackage A in InfoCube C
- Load data through InfoPackage B to InfoCube C
- Delete duplicated request previously loaded through InfoPackage B in InfoCube C
- Create index in InfoCube C
However, when I activate the process chain, a warning message is prompted: No type "Delete Overlapping Requests from InfoCube" process allowed infront of process "Execute InfoPackage" variable ZPAK_4GMFI
Would anyone tell me why such warning message is prompted?
Many thanks!
Best regards,
Marcus

Hi all,
Re Ranjan:
I previously config the process chain like that:
(1)   Delete index in InfoCube C
(2)   Load data through InfoPackage A to InfoCube C
(3a) Delete duplicated request previously loaded through InfoPackage A in InfoCube C
(3b) Load data through InfoPackage B to InfoCube C
(4)   Delete duplicated request previously loaded through InfoPackage B in InfoCube C
(5)   Create index in InfoCube C
where (3a) and (3b) is executed simultaneously.
However, (3b) often reports error. I guess it may be due to the parallel run of (3a) and (3b). So that's why I set the process chain to be executed in serial.
Re Jacob:
I found that the process chain can be run even a warning message is prompted when activating the process chain!.
Thanks you all for your kind support!!
Best regards,
Marcus

Process type "Delete overlapping request in cube " in process chain

Hi
can somebody suggest me where i need to place the process type "Delete overlapping request" for an infocube.
Regards,

Hi,
When you use the corresponding process in the process
chain maintenance screens to specify the conditions for
automatic deletion, these conditions are applied to all
the InfoCubes for the selected InfoPackages
Overlapping: If you set this indicator, existing requests are also
delete from the InfoCube if the selection criteria of the new request partially or wholly overlap the selection criteria of the request to be deleted
Same or Comprehensive: If you set this indicator,
requests are only deleted from the InfoCube if
the selection conditions of the new request are
the same as or more comprehensive than the selection
conditions of the request to be deleted.
Thanks

Process Chain - Unable to delete overlapping request

Hi Gurus
I'm in the mid of creating process chain to load transaction data in which I need to delete the previous load that loaded in using the same DTP previously
In the process chain , i have included a process "Delete Overlapping Request from Infocube" . Once i'm in the screen of maintain variant for this process, i selected DTP as the object type but unable to find the DTP that i have created under the object name.
Can someone point out what is missing
Thank you

Hi,
Looks like you need to give the the techincal name of the DTP. if you are un able to find the technical name of the DTP you can find that in the transport organizer.
just drag and drop the infoprovider ( with dataflow before) you will ge the DTP as required.
note the technical name of the DTP .
include the technical name in the process and activate the process.

Process chain is not deleting overlapping requests

Hi all,
I did all the steps like I described on my earlier posts to delete the overlapping request from infopackage through process chain. I tested it in development and it works fine with any condition, I mean automation through event, date and after seven days. When it comes to production it is not giving me the same result. So when I checked the infopackage of production I saw a routine added in the data selection of infopackage to load two days old data in the routine. We do not have that added in the development. Now if this is causing issue, can I add a step in the routine to delete previous request after loading file in the data selection.
Code:
data: l_idx like sy-tabix.
read table l_t_range with key
fieldname = 'calday'.
l_idx = sy-tabix.
zdate = sy-datum - 2.
l_t_range-low = zdate.
l_t_range-sign = 'I'.
l_t_range-option = 'EQ'.
modify l_t_range index l_idx.
p_subrc = 0.
Please help,
Suni.

Hi aanjaneya,
If you want to select and delete only the previous request of previous day, go to the infopackage and in data target tab there is option for each data target for setting the automatic deletion.
If you select it, you will get a window which has the option to delete the request. Select all the conditions and same or more comprehensive check box and also check the request date to yesterday and today option.
This will delete the request loaded yesterday and also with same selection from same source.
Hope this is clear.

Process Chain which loads data to a cube

Hi All
Please help me create a process chain in BI 7.0. I have to load the data in to a cube and before that i need to delete the existing request in the Cube. I think i should use " Delete overlapping requests from Infocube". In the maintain variant for this process type what object types i need to add. Do i need to add both Execute infopackage and Data transfer process objects.
Regards
Naga

Hi Ravi
I am loading the data from PSA to Cube using DTP. Actually my data source is export datasource (8ZHYP- prefix 8). So accroding to your answer i should use DTP object type in the process type delete overlapping request. But when i create a variant for that process type it is getting Indexs > Create Index > Data Transfer Process > Request to delete data in the infocube.
I just want to delete the data in the infocube before i load the data. So can i delete all the remaining processes.
Regards
Naga

Questions on process chains

Hai all,
I have two questions on Process chains.
1. I created a process chain for master data and a process chain for data loads(with ODS and cube). As the Master data has to be loaded first before loading transaction data, can I include the Master data process chain as a local process chain soon after the start process and then only after loading master data, the system proceeds to transaction data?
2. I designed a process chain with the aggreagtion and compression of cube data. I have forgot to check the option delete overlapping requests in the infopackage to load the infocube. I ran the process chain and now there are 2 requests and the duplicate documents. I want to delete the recent request and check the deleting duplicate requests option in info package and re run. The problem is the system is not allowing me to delete the recent request.
I appreciate any kind of help.
Thanks.

Hai Bhanu,
Thanks for the reply. I am sceduling the request for deletion in the Manage infocube> but the request is not getting deleted. Everytime I click refresh, the delete icon disappears and the screen becomes as it was before scheduing the deletion. I checked after sometime, even then the same thing...
I wonder the collpased requests can not be deleted???

Process chain taking long time

Hi,
I developed a Process chain. In developemnt for Completion of the Update rules(Start routine) its taking 60m( for around 50,000 records).
After transporting the Process chain to Production for Start routine completion (For 1,70,000 records) its taking 7hrs and sometimes its failing as the "Process is Over due" and sometimes due to "Short dump".
How to handle this.........
Thanks

Hi js,
Check the ST22... Any dumps
Check out for the short dump in source system and try loading the delta again
then
I have got the problem when u have posted...but little later.Even I was about to post the issue.. Actually my issue was...
My PC is like this
1) Start Process
2) Delete index
3) Load IP
4) delete overlapping request
5) create Index
6) ABAP program
Process chain hangs at Overlapping requests process type but the status was yellow. And the previous step (3) was success. From there its not moving to next further steps.. But the Job in SM37 was canceled.
I saw Ur post and saw the note 833168 and which matches exactly our issue.
Like we run the PCs thru the TIDAL where due to some problems PC got triggered twice... I can see the two logs in the PC. (Log view) and two requests at RSMO.
Everything was recovered again thru manual steps. This is the first time we encountered... the note helped us ... We now are very cautious about the Tidal runs...
Now PC is running perfectly
we have instructed the Supported team to make the necessary changes or fix this issues in TIDAL...
i hope this is helpful to u
bye now

Creating cube index in process chain

Hi,
From my previous post I realized that we build index of cube first and then delete the overlapping request from cube.
(http://help.sap.com/saphelp_nw04/helpdata/en/d5/e80d3dbd82f72ce10000000a114084/frameset.htm)
If I design a process chain in which I delete the overlapping request first and then build index then in the checking view it does not give me any error.
The process chain also works fine.
How does it hurt to have it this way or what is the concept behind having the sequence as recommended by SAP.
Thanks,
sam

Hi Sam,
Writing performance is increased when there is no index --- So we delete the index before updating data.
Reading Performance is increased when there is a index -- So we create Index so that when queries are executed quickly by reading the data in the info-cube.
BI Best solutions suggests that old requests are to be deleted before loading new one.So we delete ovelapping requests.
Hope it helps.

Duplicate records: Process : Delete Overlapping Requests from InfoCube

Hi Experts,
We are loading data in standard costing cube with standard available option Full upload. In our process chain we have included process type "Delete Overlapping Requests from InfoCube". In our scenario we always load yesterday and today's data. In this case after loading yesterday's data, we need to check and delete the overlapping requests and then upload todays data.
Many a times this deletion process is failing due to message "Couldn't lock cube" because it is already locked by user "ALEREMOTE". This cause system to duplicate the records in cube.
How we can avoid this?
Alok

I tried running again and it again failed. Checked in SM12 and found this entry
800 ALEREMOTE 08/14/2007 E RSENQ_PROT_ENQ CREA_INDX ZCCA_C11 DATATARGET CREA_INDX ###################################### 0 1
This locked is not released since 14th. Is there way to remove the lock using some process.

Loading through Process Chains 2 Delta Loads and 1 Full Load (ODS to Cube).

Dear All,
I am loading through Process chains with 2 Delta Loads and 1 Full load from ODS to Cube in 3.5. Am in the development process.
My loading process is:
Start - 2 Delta Loads - 1 Full Load - ODS Activation - Delete Index - Further Update - Delete overlapping requests from infocube - Creating Index.
My question is:
When am loading for the first am getting some data and for the next load i should get as Zero as there is no data for the next load but am getting same no of records for the next load. May be it is taking data from full upload, i guess. Please, guide me.
Krishna.

Hi,
The reason you are getting the same no. of records is as you said (Full load), after running the delta you got all the changed records but after those two delta's again you have a full load step which will pick whole of the data all over again.
The reason you are getting same no. of records is:
1> You are running the chain for the first time.
2> You ran this delta ip's for the first time, as such while initializing these deltas you might have choosen "Initialization without data transfer", as such now when you ran these deltas for the first time they picked whole of the data.Running a full load after that will also pick the same no. of records too.
If the two delats you are talking are one after another then is say u got the data because of some changes, since you are loading for a single ods to a cube both your delta and full will pick same "For the first time " during data marting, for they have the same data source(ODS).
Hope fully this will serve your purpose and will be expedite.

To set delay in process chain using a program

Hi all,
We have a requirement in which the loads from nearly 15 sources (DSO) gets loaded into the Cube thro 15 process chains. The source gets loaded from the PI interface. So it might happen that simultaneously 10 loads will be started and reach the cube.
In the cube we have delete overlapping request, so its gives a deadlock when the chains try to delete the prev. request at the same time.
What we have planned is if we can write a program that will set a delay depending on the lock entries present for that particular cube. But still we are not sure how far this will help.
If anyone has faced a similar issue or can anyone suggest on this would be much appreciated.
Thanks
Merlin

I believe in each of your 15 local chains you have the load to Cube process.Why dont you take the load to the Cube out of the local chains and in the meta chain you could sequence the loads from the 15 ODSs so that you can have a parallel processing upto the ODSs ( assuming the rest of the local chain is used to fetch from R3 ) and then sequential to Cube.
I dont think writing a program will help much here.

Problem in creating process chains for CO

Hi Friends,
                 I have a CO cube "0OPA_C11" getting data from Three datasources,
those are 0CO_OM_OPA_6(supports delta), 0CO_OM_OPA_1(full only), 0CO_OM_OPA_2(full only), i have already created process chain to this cube using these three datasources, the chain is like this,
1. delete indexes
2.0CO_OM_OPA_6(supports delta
3.0CO_OM_OPA_1(full only),
4.0CO_OM_OPA_1(request overlapping)
5.0CO_OM_OPA_2(full only),
6.0CO_OM_OPA_2(request overlapping)
7.create indexes
        Is it right? here the chain is running, after completion of that, in manage of cube, it is showing only the request for 0CO_OM_OPA_2(full only), the request which were there earlier like Init request and new delta request for .0CO_OM_OPA_6, full request for 0CO_OM_OPA_1 are getting deleted, it is showing the request only for 0CO_OM_OPA_2,
the way how i created the process chain is right or wrong? can anybody give me the solution?
Thanx in Advance
BalajiReddy

Hi Nick,
          Thanx for your reply, everthing is ok what you've asked me to check, i think there is certain scenario to create the process chains for the data targets, which are getting data from multiple datasources, which support delta's as well as full.
          I want that scenario, can you tell me? or can anybody tell me?
The right points are assigned to the right answers.
Thanx in advance
