Reg delta in process chains

Hi,
I'm doing a flat file extraction. The data flow is from Flat file to ODS and then to cube. I need to create a process chain to automate the process.
As per my understanding, the load from a flat file to the ODS is always Full update. Am I right?
The first load we are planning to do a Full upload manually, after which we plan to automate the process using process chains.
Please provide me with inputs on the steps to create a delta from the ODS to the cube.
Thanks.
Darius.

Hi,
Welcome to SDN.
You can autmate the process by having the flat file in the appl server. Flat file data source supports delta as well which is also called Pseudo delta.
If you wish to load your flat file in full update you can still load deltas to cube from ODS.
For this, run a inititliazation w/o data transfer from ODS to Cube and then create a delta IP from ODS to cube.
While creating a process chain, follow this procedure
Start> Load info package ( flat file)> Activate ODS--> Delta IP to Infocube.
hope this helps

How to handle delta failed process chain steps

Hi All,
I have a query regarding process chains were in processstep has delta load and there is dependency between the predeseccor and successor process steps,then
if the delta load fails due to any one of the following reasons
1) due to remote_icp locked the prtclr Infoobject the process step is executing .
2) due to any psa records errors and so on
Then how to handle delta and see that correct delta records were updated .
Because again for the nextday loads if the previous delta is incorrect it will give pop-up message that it is not possible.
If any suugestions pl guide me.
thanks

1)Remove the lock by force from sm12 or wait till the lock is gone.Then see if the delta data has come till the PSA.Mark failed delta load RED and back it out from target.Then read everything in manually from PSA to target.
In process chains u can go the monitor entry for the failed load by..highlight chain..click log icon..give selection..for proper selection..see the failed node..right click..display messages..click on process monitor.
Sometimes even if infopackage is run successful manually,next steps in the chain do not kick off.
Use Siggi's excellent blog on this..(it works really well)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
2)Make request RED and back it out from target.
Correct records in the PSA and read everything in manually from PSA to data target.
Then use Siggi's blog.
If data hasnt come to PSA do a delta repeat.
Always check yesterday's chain run about 1-2 hrs before today's chain kicks off.
cheers,

Red Light, followed by successful deltas in Process chain

Hello,
I have a DELTA dataload the runs in the AM and then again in the PM. This occurs every day.
2 days ago the load Red lighted. It loads to an ODS. I didn't notice this redlight and the chain kept running. So the subsequent loads were successful, but not activated.
In this case, would the next Delta load that the process chain run automatically be a 'REPEAT' delta?
In which case I can manually force the Total status of the failed load to red and delete from the ODS, and then activate the unactivated successful loads?
Thanks,
Nick

Hello Reetu,
I checked the "Type of Data Update" column in the ODS, and it does not indicate "Repeat Last Delta".
The Failed Data load, did not have any records transferred or added to the ODS. Also this ODS does not update to any furthur data target.
Because the Failed data load did not have any records transferred or added, is a repeat necessary or can I simply delete that load and activate the subsequent loads?
Thanks,
Nick

Reg : To view process chain flow for a cube

HI Experts,
I need to view process chain flow for a particular cube of sales distribution.Can you please tell me stps to perform .

Hi,
If the cube is already loaded then you can just to the infopackages which are loading it and in the infopackages you have option in the "schedule" tab to see which process chain it is loading.
if not then you will have to identify which data source is loading to the cube and check for the infopackge.
and I think the DTP will be in the same chain as well.
For DTP it is alreday mentioned by the others.
Thanks

Unable to load deltas through Process chain(PC)

Hello Experts ,
I have scheduled the PC , deltas are not getting loaded from PC.
Load type : Immediate , periodic updates : for every 30 min.
(ii) Stopped the PC and tried to run deltas manually
Status 0 from 0 records in ODS
also 0 from 0 records in PSA
RSA3 contains records.
1.Can I load all the deltas without PC. (or)
2.What changes should I take to run deltas through PC.
Kindly help
Points will be assigned.

Hi Vijay,
Your not getting the records into Bw Right. on Which Functional module ur workin in BW ( i.e ur SD,FI,MM) why bcoz if it is other than FI
u have to check R/3 side
1. "Jobcontrol" has done periodically for every 30min (why bcoz ur pulling data for every 30min right) OR Not.
If Jobcontrol has not done u have to to do periodically for every 30 min .
2. Next u have to pull the data It will work definately.
I am very much sure about this.
Do period Jobcontrol for every 30 min in Source system.
Thanks,
kiran.
IT will work surely.

How to set delta load in process chain

hello all
The scenario is i created process chain for transaction data and all the infopackages are in initial load now I want to do delta,how to set delta in process chain,bcoz only the new records should load?
kindly anyone let me know.
regards
balaji

Hi Balaji,
In most projects thay dont have the "init" infopackages in the process chain. They have 2 infopackages for a load - One for init and the other for delta. Now that you have created the process chain what I suggested was to change the infopackage settings to delta load and change the description of the infopackage.
The other option would be to create a new infopackages for delta and include them in the chain replacing the "init" ones.

Error in process chain (psa data)

We have got an error in our PROCESS chain for master data.
Info object Name : 0customer
In that it was showing there was error in our request. When I wanted to correct data in the request there it was showing no error records. All the records are good and also it is showing as error in request. I have deleted the request from infoobject and also from the PSA. And the last updated good request is also showing error as No data packets available for the request .
0Customer is delta update ; Process chain is daily based.
My doubt is whether the records in the deleted requests will be reloaded again from sap R/3 into PSA, as requests during Process chain or not.
While monitoring the request details in Monitor u2013 Administrator Work bench, it shows the following:
1.     Requests (messages) Everything Ok
2.     Extraction (messages) Missing messages
3.     Transfer (IDocs and TRFC) Missing messages
4.     Processing (data Packet) No data
5.     Process chains : Everything Ok.
Even after deleting the requests my process chain is not getting updated.
Kindly help me in solving the above problem
Regards
Padma

Hi,
Once deleted the request, try to manually trigger the load and see whether it completes. if it completes and pulls reocrd then you can push the chain process ahead with the program RSPC_PROCESS_FINISH

Process Chain Issue Help needed!!!!!!!!!

Hi all,
Please help me in creating process chains, Requirement is
Process Chain1
Infosource --> ODS1 (Delta Load) From ODS1 --> Cube 1 (Delta Load)
Process Chain 2
from same above ODS1 --> ODS2(Full Load) and ODS2 --> Cube2(full Load)
What is the sequential flow?
I created the chain 1 as
Delete Index(Cube) > Infopacakge from Infosource to ODS1> Activate ODS1 > Update ODS1-> Generate Index(Cube).
For Chain 2
Delete Index(Cube) > Infopacakge from Infosource to ODS1> Activate ODS1 > Update ODS1->Activate ODS2 > Update ODS2> Generate Index(Cube).
My question is for Chain1 from ODS1 it should be Delta and for chain2 from ODS1 it should be full load,
i have chacked the ODS1(8ODS1) infopackages the full load infopackage data target is ODS2 and Delta Load data Target is Cube1.
Thanks in Advance,
Sudha.

Below..i believe is a better design for the process chains..
Chain 1
Start variant> Infopacakge from Infosource to ODS1> Activate ODS1 --> Delete Index(Cube) >Update ODS1-> Generate Index(Cube).
(drop cube indexes just before cube gets loaded)
Chain 2
Start variant> Infopacakge from Infosource to ODS1> Activate ODS1 > Update ODS1->Activate ODS2--> Delete Index(Cube) > Update ODS2> Generate Index(Cube).
(i think we can remove 2 steps(in bold)..right?ODS1 already got loaded in first chain..just we need to keep dependency that 2nd chain runs after the 1st chain has run)..
U can have a 3rd chain..a meta chain like..
start variantchain 1chain 2..
(for both chain 1 and chain 2..i mean the local chains...set start variant parameter as 'start using meta chain or API)..
doing so..chain 2 will kick off only after chain 1 is successfully run..
(also check if the process type 'further update from ODS to data targets..allows you to choose data targets..and choose full/delta..i doubt it..
if it doesnt allow..then place the infopackage steps instead of this 'further update' process..i have done this earlier..)

Process chain developement doubt

Hi,
I am developeing small process chain for loading master data(Delta).
I have already done innitial load of master data in infoobject, now i am developing a process chain to load delta master data. My question is shall i need to use different infopackages than used for initial load OR same infopackages used for initial load can be used for delta load process chain of master data.
please reply.

Hi,
Best practice is to use different infopackages.
But the same InfoPackages can also be uesd in the Process Chain. No harm.

Delta loading and Process chain BI

Hi experts,
Two Issues.
1)As i am loading FI data into dso through a process chain which includes Start process>Delta infopackage(which gets data upto psa)>Delta dtp-->Datastore activation.
But infopackage is picking up deltas but DTP is picking up all the previous records plus deltas.
100 records -- 1st day throught Intialization of Delta with Data Transfer
2 delta records -- 2nd day
But DTP is picking up 102 Records on the 2nd Day, which means it is also picking the old records as well.
The DSO must have just 102 records but it is having 202 records.
2) A process chain in running daily as scheduled , but I rescheduled with new scheduling options without deactivating the Process chain.
My Question is
Will the Process chain run for the OLD and the New Schedule or
Is it going to run for new schedule or old one?
or
will I face any Problem because I did not deactivate and made changes to the Change.
Please help me in this matter.
Thanks in advance.
Bhadri.

First query:
I believe that u have used FUll update type DTP is instead of the Delta DTP.. Please cross check the Update mode of the DTP once.
To resolve this issue, delete the total content of the DSO as u have Init and delta loads in PSA. And then using the Delta DTP of the Process chain, load the data. It will extract the total cotent what ever is there in PSA, and later the same DTP will act as the Delta type and will pick the data from the New request of the PSA.
Second Query:
Its always suggested to deschedule the process chain before changing the schedule timings. When ever u do this type of scheduling, just check how many number of JObs available in Schedule mode, if u can see more than one, then delete the older one and keep the new one as it is.
But I always suggest you to deschedule the process chain and reschedule PC with the new timings and then activate the same.
Thanks

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.
Thax & Regards

Error in Process Chain for Delta pack

Hi All,
Here I am facing error in process chain for delta pack.
Error:
Last delta upload not yet completed. Cancel I
Please send me the solution asap.
Thanks

Hi,
This message means there may be a load triggered by the same infopackage that may be still running or may be still having yellow status. Go to the monitor screen from this IP itself and it will show the paricular request (it will be the latest one). See if that load is active and running. If its active try to find out if load is happening, if its happening you may let it progress. If its not active you need to force the status to red and delete from the target. Once this is done you can retrigger the load. If its a datamart load you may need to reset the data mart status before the triggering the load.
Refer
Last delta update is not yet completed
Last delta update not yet completed-PC Chain Error
Last Delta Not Yet Completed
This is the same issue as yours.

Delta datasource management in process chain

Hi experts,
I have the following problem with process chains.
I have one Delta infosource used to load two different infoproviders (ODS1 and 2).ODS 2 must be loaded only once ODS 1 is loaded and activated. The Delta process implies that the 2 ODS are datatarget for the delta infopackage.
In my process chain, I have :
'execute infopackage IFPCK1'
(with 'only PSA' option and of course the two datatargets ODS1 and ODS 2 selected)
then a first
'Read PSA and charge datatarget process'
(with options : datatarget = ODS 1, execute infopackage IFPCK1)
followed by
'Activate ODS' ODS 1
then a second
'Read PSA and charge datatarget process'
(with options : datatarget = ODS 2, execute infopackage IFPCK1)
Each time, I run the Process chain, I have the following message for ODS 2
"the request (ODS1) already exists in infocube/ODS; Not loaded."
It is as if the first Read PSA process tries to load both ODS instead of only one.
Any suggestion to help me slve this problem ??
Thanks in advance

Hi Daniel,
unfortunately there is no easy way around this. I would suggest to create an ODS 3 as exact copy of the info source and load ODS 1 and 3 in parallel and then ODS 2 from ODS 3.
Best regards
Dirk

Delta load problem in process chain

Hi,
I have ODS givng data to another ODS. The init of this flow was done manually...Now i have created process chain in which further processing has variant as "execute infopackage" as the delta package made .. now when i check this process chain its giving me error ""Delete init. request
REQU_49LKNGG0SE5966D3S7SQYYDQX before running
init. again with same selection"" .. Actually this is not the Init req which i ran manually..this is the req which was run when i ran this process chain... what shld i do to add only delta IP in process chain so that i dnt ve to delete init
Thanks
Prashant

hi,
first load all the init loads from the ods to cube. then u have to create the delta infopack and include that in the chain.
create the int info pack under the infosource 8<ods name>
trigger that infopack, create the delta infopack under the 8<odsname> infosource , and you have include that in the PC.
Please do changes in your process chain.
Local chain 1 - start -> load to ods -> activation of ods ->further processing(remove the infopack in this process maintain variant).
Lcoal chain 2 - start -> delete index ->load delta to cube -> create index -> roll up (if needed)
Main chain -> start -> local chain 1 ->local chain2
