hi Suneel,

Using partitioning, you can separate the dataset of a PSA table into several smaller, physically independent, and redundancy-free units. This separation can mean improved performance when you update data from the PSA. In the <b>Implementation Guide with SAP NetWeaver > Business Intelligence > Connections to Other Systems > Maintain Control Parameters for Data Transfer</b> you define the number of data records needed to create a new partition. Only data records from a complete request are stored in a partition. The specified value is a threshold value.

at database level

If you are using this database you can also partition PSA tables. You first have to activate this function using RSADMIN parameter DB4_PSA_PARTITIONING = 'X'. SAP Note 815186 includes more comprehensive information on this.
hope this helps.

Hi,
psa data can be deleted by means of different ways.
In process chains ,we have option " delete request from psa "
or
go to your data source --context menu ---manage --we can find out requests in psa, choose the requests what we are going to delete and click on trashcan icon ( delete ).
or
go to se14 tcode, give your psa table name and check for option delete.

How to delete all the PSA data in one go

Hello Guys,
I want to clear all the data from all the PSA tables at one shot, how can i do this??
I have tried following things:
1) I have gone to PSA root node and right click and then clicked on delete PSA data, but its showing me all the datasources and when i am executing that, it is deleting one by one(that i means i need to select individual datasource, which i do not want).
2) Above specified step runs RSPSADEL1 in background , so i doubt whether it deletes psa data only or complete Table?
3)I got the info from other posts that there is a fm which is RSATREE_PSA_DELETE_BATCH, but i need to make myself clear whether this fm deletes only data or complete Table?
I am using sap-bw 3.5.

How can i update data of DSO and Cube using ABAP??

Hello Experts
I have a requrement in which i need to update/ delete data from DSO and cube based on certain keys using ABAP.
Please let me know how can i modify contets of cube or active table of DSO.
Thanks
Sudeep

Hi
I have requirement such that i need to update certain key figures in DSO after certain time.
for eg. say record with key a is loaded to DSO and currospoding key figure was loaded with value 10
after few days because of certain parameters changing in system i need to modify key figure value.
currently i am doing same using 1 self transformation i.e. by loading same data again in same DSO.
Amount of data is very huge and causing performance issues in system.
now A is not key but i need to modify record for few combinations which apperar multiple times in DSO.
Same DSO data is loaded into Cube regularly.
I may need to update data after gap of few weeks as well.
This design will be used as template and needto keep whole logic generic.
So wring Function module can make it generic.
Thanks

How can I stop music and movies from being automatically deleted from my phone and saved on the cloud? I've just tried to watch a movie on my 2 hour commute, but yet AGAIN it has been removed. I do NOT want to spank all of my data allowance

How can I stop music and movies from being automatically deleted from my phone and saved on the cloud? I've just tried to watch a movie on my 2 hour commute, but yet AGAIN it has been removed. I do NOT want to spank all of my data allowance downloading it again, especially because (believe it or not) I added it to my phone because that's precisely where I wanted it!! Any help much appreciated

FYI I had to put this link into firefox to reply - because **** back safari just wouldn't register my clicks to any of the links on the post... Despite reloadeing and even restarting my computer. Totally annoying and a massive pain in the ***.
But in terms of my initial query; thanks for responding. But no, this is NOT the cause of the problem. I have auto sync and sync over wifi activated, but have also selected manually manage music and videos. Plus, all of my music and videos are on my macbook, absolutely all of it, so if it my phone was syncing with my macbook everything would still be on the phone. Life would be peachy if my phone jsut copied everything that was on my macbook, but unfortuantely it keeps deleting tracks for no apparent reason.
Any thoughts greatly welcomed, because at the moment i can only conclude that my iphone is crap.

How can i Read and Delete data in Infocube

Can some help me how to read and delete data in infocube before loading data from direct DSO.
I should be able to read and delete condition with combination (0FISCPER, 0COMP_CODE).
Let us say we load JAN, comp _ code : 0001 (10 records )and JAN comp _ code :003 (30 records ) and JAN, comp _ code : 004 (20 records ) to infocube
second time if DSO gets data of JAN, comp _ code : 0001 (40 records ) it doent need to be 10 old + 30 new, it can be 9 old 21 new lay i need to delete 1 old rec which i dont need. so that is the reason i want delet all JAN, comp _ code : 0001 recods before loading.
Can some one help me

Hello,
You could use the selective deletion available with the cube to get the selective data for 0FISCPER, 0COMP_CODE combination deleted.
If you go in the manage of cube & Content tab, you would find the selective deletion option at the bottom of screen.
If you enter the option, you could give your selections for deleting the records and run the job.
Please let me know if you need any more help.

In a PrC, how to delete data from the PSA that have been loaded in Prcs Chn

Hello,
In a process chain, how can I delete the data from the PSA that have been loaded within that process chain. I don't want to delete data that belongs to other business units that use the same datasource.
Thanks,
Andre

I dont think so you can achieve that, PSA is actually datasource dependent.
One you load from a datasource to PSA.That is accesible by multiple DTPs if you have created so.
As you said "I don't want to delete data that belongs to other business units that use the same datasource."
If you delete the PSA, you may have to repull the data from source system again and if thats delta it wont work out.
As said by above ppl you can include the "Delete PSA" in process chain but choose some 15 days buffer.
Hope this helps.

How many days we can store the data in psa & ods ?

hi guru's
how many days we can store the data in psa & ods ?
Thanks & Regards.
Prabhakarreddy

Hi Prabhakarreddy,
As many days as you like:
In the PSA you can keep data as long as you like but you will need more and more disk-space. So its advisable to clean up from time to time.
Example:
PSA's from full loads Clean up in a weeks time,
PSA's from Deltas: Clean up after you are sure data is correct. (e.g. a month or 90 days)
Remember that you cannot do a reconstruction from dataloads of which you have deleted the PSA. If some thing is wrong you will have to do an Init again!
In ODS's you must keep data in order to keep your delta loads to cubes in order. Removing data will force you to do a new initial load.
Sometime companies delete old data form ODS's that is older than a certain period (e.g. more than 3 years old) by running a selective deletion. You will have to do an init again. But loads and activation may run faster and of course you gain on disk space.
