PSA deletion

Hi Expert,
I have an issue with PSA deletion. There is one PSA table which is already included in the PSA deletion chain. we have checked this PSA deletion step and it is working fine. when i go to manage option of data source , I find only seven requests as per my expectation.
Whereas Early watch report says this PSA has consumed 400 GB. This figure is constant from last one year.I have checked with Basis guy and they said they cannot do repartitioning.
Only option I have to truncate this table at OS level.
Does anyone know any other option which can be used to free this big chunk of DB space?

Hello Dhiraj
things I would do here.
1. Consistency check of PSA via RSRV
2. Check the PSA table name from Manage screen and then try to see what is the exact amount of space it is taking from DB02.
3. If you are on oracle you can check what is the space actually required versus what is the space this table is taking. You can get this information from early watch report ( based on your ST-PI version) or you can run a script to check that.
If you find actual space required is much less than what it is consuming right now you can go for re-organization.
Please note single table reorganization is possible via brconnect and that can be done online
4. If nothing works last option is to truncate the table ( based on your business requirement obviously ). You or your Basis team member can do it even from SE14. I do not find any need to waste 400 GB of space for one PSA.

Source system in PSA deletion variant

Dear Experts
In process chain PSA deletion variant,in source system column I will give the Development source system name(C6D),and after transport to the Quality styem(C6Q) Should I change this source system manually in qualtiy or system automatically will pick up the corresponding source system name?If not,what is the possible solution since we dont have any access in quality system.
Cheers
Rajesh

Thanks for the reply.I got doubt because in DEV we have to enter manually both DS and SOURCE SYSTEM manually...after importing to Quality will it change the source system name?...Can i take for grant...Pls confirm....

H how to find if the psa table is included in psa deletion process chain

Hi all
can anybody tell me .
I have a psa table it's technical name is /BIC/B*
h how to find the above psa table is included in psa deletion process chain or not
please help me

Hi
Ope the PC in RSPC1 -->go to planning view of process chain
in left side you will find different types of process types.
under other BW process types folder -->you will find process type "Delete request from PSA"
drag this into your process chain planning view and customize it based on your requirements.
check the below article for step by step procedure

/BIC/ namespace not modifiable, can't create PSA delete variant in process

Hello,
When I attempt to create a PSA delete process in a process chain, I get an error message as such:
Namespace '/BIC/' must be set to 'changeable' (transaction SE06)
Message no. R7063
I have had Basis dot his for me before and it worked, but it takes a lot of change menagement to do this. I have asked Basis to leave it modifiable in SE06, but they will not. Is that the only way to be able to create PSA process variants is to have Basis use SE06? I looked in Object Changeability, but nothing stuck out. I should not have to have Basis do this task every time. Please let me know if there is a better way.
Thank you.
Brent

Hi Brent
I believe /BIC/ namespace should remain modifiable where you are creating PSA deletion process.
You can check if that is the case in your system.
Check in TRNSPACE table with namespace /BIC/ .. changagle flag should be X. I think it should be in your production also

PSA deletion -clarification regarding QM status

Hi Guru's
We r on BI 7.0 SP13. We are loading HR data with full loads via infopackages to PSA and subsequently from PSA to infocubes via DTP. We have configured a process chain to delete the PSA requests which are 1 day old in order to make sure that we do not have duplicate records uploaded via DTP from PSA to infocube.
The setting on the PSA deletion is to delete requests that are 1 day old and only sucessfully booked requests/updated in data targets. If we maintain this setting system is not deleting the PSA requests which are more than i day old. but if i remove the checkbox for "only successfully booked requests" system deletes all requests which are more than 1 day old.
When i checked the status of the requests, it has a "green" color for technical status and the radio button " back to technical status" is selected. My question is Does the system check if these PSA requests are having QM status is green before deleting them if we select "only sucessfully booked requests"? if yes how to set the QM status as green automatically in the requests that are only loaded to PSA?
i also verified the table RSREQDONE in order to check if these PSA requests are having "QM status fields" populated. only technical status were green for these and the QM status fields were not populated.
I want to get a clarification whether these requests that load to" PSA only" are supposed to have a QM status or they are supposed to have only the technical status? if they are suppose to have a QM status , then how to set it automatically ?
thanks

Hi Anil,
Full Upload Request does not concern any DELTAs whatsoever. Just populate the SETUP Tables in R/3, give parameters (if any) and load, thats it. Thats why you dont need to switch previous request to RED because a FULL Request does not care on the status of the last update.
DELTA Update Request is different. The system needs to know if the last DELTA extraction was a failure or success. It needs this info so that the system will know if it will request for a new fresh batch of updates (DELTAS/Changes) or RESEND previous batch of updates (DELTAS/CHANGES) in case the previous DELTA Update is a failure...
Hope I have helped. If i did, please grant points...

PSA Deletion Issue from the Process Chain

Hi,
I am facing problem in PSA Deletion from the chain. Scenario and issue as follow:
Scenario:
I have a PSA deletion Chain which got trigger daily. Which contains the many "Deletion of Requests from PSA" step. Datasources in the steps are from 3 different source system. Previously all are working fine. I am using 7.1 version.
Issue:
1. All PSA Deletion step working fine except the BW source system Datasources.
2. Few of the Datasources from BW source system are working fine(i.e, deleting the requests as per the condition given in the step.) and few are not(i.e, it does not pick up any request for deletion, but it have to delete some requests as per the conditions.).
All the PSA deletion steps are turns to green when chain executed.Few of them is not working from august and few are from the october(i.e, Not any specific date)
Please suggest me the solution for above issue.
Thanks in Advance.
Himanshu.

Hi ,
Goto display/maintain variant of the PSA deletion step and compare conditions of the Infopackages which delete data successfully with those which do not .
The condition given for the info-package whose data is not deleted from PSA , is not being satisfied that might be the reason the request is not deleted from the infopackage.

PSA deletion variant - Syntax error in program "SAPLRS_PSA_DEL_GUI

Hi.
Recently, we have implemented the note 1357168 to overcome the error "Object name &1 after the prefix has to start with ABC...XYZ".
But after that if we maintain any PSA/Change log variant we are getting the below error Syntax error in program "SAPLRS_PSA_DEL_GUI.
We have identified the class CL_RS_PSA_DEL_MASS_DELETION for that. but not able to figure it out what is the issue.
please help.

PSA Deletion variant in Process chain

When I add more than one PSA tables in one process step of Process chain would the deletion happen sequentially or parallelly?
In other words, if I have some 20 PSA tables to be deleted, can I put all of them in one step or should I put them in different steps - some 4 or 5 steps - to reduce load on system? (I need to keep only 2 days data in each table).

Hi,
it will happen sequentially. You can put them in one process step.
However, I recommend to include the PSA deletion systematically in each corresponding chain since you can control it and monitor it better.
hope this helps...

PSA Deletion through Process Chain

Hi Experts,
Currently I am working on the BW3.5 version. I would like to delete the old PSA req through Process Chain. I need some clarification. Please provide me your suggestions. Thanks in advance.
1)In SAP-BW 3.5 version, there is only one process type u2018Deleting Requests from the PSAu2019 is available to do this activity. This process type can delete the requests from the PSA only or Will it delete PSA and Change Log tables!!!!! In the SDN threads, some people said it delete the PSA requests only and some said it delete the PSA requests as well as Change Log.
2)Currently we are having six process chain and each has master & transaction data load(Data load through PSA).
Similarly I am planning to create six PSA deletion process chain which includes master & transaction data deletion. Here I am got little complication on finding Object Name(PSA Table Name).Please refer the screen shot.Is there any short cut to find full list of Object Name(PSA Table) which is currently available in the Process chain every day load.
3)On the request selection, i prefer "Only sucessfully booked/updated req.". I did not select"Only those req with errors,that are not booked in a data target". Please share your view on this selection preference.

Hi Murali,
Thanks for the response. I do understand about the identifying the data source & PSA retention period(days). Let me elaborate my question little more. Thanks.

In the SDN threads, some people said it delete the PSA requests only and some said it delete the PSA requests as well as Change Log.If i am not mistaken, In BW 3.5 PSA deletion will leads through Change Log also.Am i right?

Here I am got little complication on finding Object Name(PSA Table Name).Please refer the screen shot.Is there any short cut to find full list of Object Name(PSA Table) which is currently available in the Process chain every day load.In the very day process chain, we are having many stages in master & transaction load. So I can go through info pkg level and find the data source,then i can identify the PSA table name. But is there any other simplest way to find the PSA table name.

3)On the request selection, i prefer "Only sucessfully booked/updated req.". I did not select"Only those req with errors,that are not booked in a data target". Please share your view on this selection preference. May i know that which option is optimal on normal business process. If i did not select both options, then will that delete all the request in PSA!!!
Thanks.

Process Chans:PSA Deletion

Hello Experts,
We are using a number of process chains (for transactional data).
Is it better to have a seperate process chain which performs the PSA deletion for all PSA tables? or is it better to include PSA deletion node seperately in respective process chains?
Please advice.
Regards,
LM.

Hi,
Its like PSA (persistent Storage area) since its a mandatory in Bi 7.0 so its loade too frequently, as a matter of fact it becomes too clumsy over the time, as a result it takes a whole lot of time to get deleted ,
including the deletion step in a Process chain will expand the running time to indefinite so its better to keep it as a seperate chain.
Hope this will suffice your concern
Thax & Regards

PSA deletion in delta

Rohit pls let me know on this.
If I delete the PSA in delta load on ODS will it be any impact. Will the load get failed If I delete the delta PSA(ODS).
Message was edited by: Tamkris Taj

Hi Tamkris,
Is it like only rohit needs to update on this or shall i go forward?
Once you have loaded the ODS, the PSA deletion should not create any problems. only incase you want to reconstruct some request, then it will be not possible as the records will not be available in PSA.

PSA Deletion - Customisation

Hi All,
I'm working in a environment where PSA deletion is not done for years! so, using Process Chains for individual PSAs is out of question. I'm developing a tool to do this.
Also, there is a requirement to do the PSA and change log requests seeprately based on diff selection criteria. As you know, Changelog and PSA share same table for storage and the SAP provided PSA deletion (RSPSADEL1) don't differenciate b/w Changelog/PSA requests. The change log requests starts with ODSR* and PSA requests with REQU*.
I planning to customize the RSPSADEL1 program to delete these requests seperately based on different sel criteria. Eg: I want to keep 1 yr of change log in few cases while need only 1 month of PSA!
Anyone done similar thing before? any hints/tips/warnings are welcome!
Thanks & regards,
Sree

Hello Sree
Did you already find a solution for this issue? I am working on the similar scenario where I will be keeping or deleting the data based on the application component.
I am seeing the function module RSATREE_PSA_DELETE_BATCH which in turn uses the program RSPSADEL1.
I will be able to link the details to application component, just wanted to confirm how to go about defining number of days to keep data in the PSA. I guess it is maintained in the standard table RSPSADEL only, kindly confirm...
Best Regards

PSA deletion in BI 7

Dear All,
Somebody has implemented PSA deletion in BI 7 in process chains but I see that the PSA is not getting cleaned up. Even though the step is green, but the PSA deletion is not happening. What are the possible reasons for this and what should be done ?
Also, if I have the PSA tables name with me, how can I know that these PSA tables are for which InfoProviders ? That is, I need the InfoProvider's name from the corresponding PSA table name..
Thanks,
Srinivas

Hi,
Have you checked all the requests, may some are in yellow staus.
Then try to make it red and delete it manually.
If it does'nt works then go to SE37 >> to execute the function module RSBM_GUI_CHANGE_USTATE >> From the next screen, for I_REQUID enter that request ID and execute. >> From the next screen, select 'Status Erroneous' radiobutton and continue.
This Function Module, change the status of request from Green / Yellow to RED.
Once it is RED, you can manually delete that request.

Debjani...
