Deleting obsolete logging tables in SLT system

Hi Experts,
Need help to sort out below issue,
There are many obsolete logging tables in SLT system ,might have been left out after dropping SLT schemas, previous replications.
These logging tables exist in ABAP dictionary but not in database. Due to this, it shows inconsistencies in DB02 > Diagnostics > Missing Tables and Indexes. There are in total 252 missing tables in DB. Currently DB migration is stuck due to this issue.
Is there any way to remove the tables from dictionary without deleteing them manually through SE14 ?
How to avoid having such tables ? Am I missing any steps while deleting the previous schemas?
Regards
Kartik

Hi Kartik,
these obsolete objects/logging could be also there becasue someone refreshed/copied the systems.
There is also one transaction IUUC_REMOTE in the source system to delete the logging tables. But I am not sure if it distinguish between db or ddic level. Have a try and post the result.
Best,
Tobias

Deletion of data from change log table and PSA

Hi,
For a DSO I want to delete data from "Chnage log table" and " PSA Tabel".
For the DSO manage screen I have seen " Environment-> " Delete changelog table" from this we can delete chnage log table data as per my understanding.
at PSA Level Mange screen also I have seen " Environment-> " Delete changelog table" from this option also it deletes the data from change log table or it deletes data from PSA table?.
if this option also deletes data from changelog table then how we can delete data from PSA table?
Please clarify me

Hi,
I am not sure what are you referring to from your point "PSA Level Mange screen also I have seen " Environment-> " Delete changelog table". When ever you click on manage for your psa you will be routed to a popup where you can see all your requests in the PSA table & there after if you click on any single request you will get Environment menu option but there wotn be any change log deletion option available. Please check again? Right clicking on your data source will take you to the manage requests for PSA. You can selectively delete the requests as required.
For DSO when you right click on manage you can directly find Delete change log data option in the Environment tab. there you can select the requests you want to delete.
Also if you want to automate the deletion process then you can simply create a chain and include the steps for PSA deletion & change Log deletion accordingly.
Also it is recommended to keep on clearing the PSA table & Chage log data at regular intervals as it saves the disk space & thus helping in performance optimization
Please refer the below doc at SDN, it will be helpful for you in automating the process of change log deletion & PSA deletion.

Change Log Table entries without Dates and How to Delete these entries !!

Hello Experts,
I was analyzing Change Log tables of some DSOs and figured out in some tables we don't have Date Column and some tables with date columns but many entries with "00/00/0000" date.
Any ideas on this ? Any idea how records can get into the table without dates and if SAP provides a safe way to remove them (without dates) ?
Many Thanks in advance, Please help.
Regards,
S. Patel

Hi Sunil
Date fileds 00/00/0000 means date are blank..that means either you did not get them from source system or the transformation is not mapped.
Do not delete change log selectively, that might affect your delta loads.
Rather delete old change log ...
From DSO administration ---use the main menu to choose Environment ® Delete Change Log Data.
For more information you can check the log below.

Deleting data from a very large log table (custom table in our namespace)

Hello,
I have been tasked with clearing a log table in our landscape to only include the most recent entries. Is it possible to do this given that the table has already got 230 000 000 entries and will need to keep around 600 000 recent entries?
Should I do this via ABAP and if so, how? Thanks,
Samir

Hi,
so you are going to keep 0,3 % of your data?
If you should do it in ABAP or on the database is your decission.
In my opinion doing things on the database directly should be done
exceptional cases only e.g. for one time actions or actions that have to
be done very rarely and with different parameters / options. Regular
and similar tasks should be done in ABAP i think.
In any case i would not delete the majority of the records but copy
the records to keep in an empty table with the same structure, delete the
table as a whole (check clients!) and "copy" the new table back in ABAP
or rename the new table to the old table after droping the old table on the database.
If you have only one client you can copy the data you need in a new
table and truncate the old table (fast deletion for all clients). If you have
data to keep for other clients as well check how much data it is per client
in comparison to the total number of lines (if only a small fraction, pefer copying
them too).
On the database you can use CTAS (create table as select) and drop table and
rename table. Those commands shoudl be very efficient but work client independently.
If you have to consider clients SELECT; INSERT; DELETE or TRUNCATE (depends on if you have
copied all data considering clients) are
your friends.
Kind regards,
Hermann

Delete Entries of Change Log Table

Can any one tell me when do we require to delete the content of the change log table of standard DSO. I am just fresher to SAP BI.
Thank You

Hi
Deleting data from the change log for an ODS object is recommended if several requests, which are no longer required for the delta update and also are no longer used for an initialization from the change log, have already been loaded into the ODS object. If a delta initialization for the update exists in connected data targets, the requests have to be updated first before the respective data can be deleted in the change log.
Only a temporary, limited history is then retained. The change log can possible become so large you might want to reduce the amount of data volume and delete data for a specific time period.
How to Delete it
Since the change log is also stored as a PSA table, you can use the function for deleting data from the PSA to delete data from the change log.
In the ODS object administration, use the main menu to choose Environment -
> Delete Change Log Data.
Or
Go to the PSA tree.
Use the main menu to choose Settings -
> Display Generated Objects, so that you can display the InfoSource for your ODS object. Your InfoSource has the same name as your ODS object, along with the prefix u20188u2019.
Use the context menu to choose Delete Change Log Data.

Delete table from target system

Hi Folks,
I have transported a table to the target system which should not have been transrpoted. The table actually doesn't meet the right naming conventions and have some unecessary fields. I want to remove the table present in the target system and transport a new table which has the right fields and right naming conventions.
Regards,
Santosh

Ask this question in ABAP forum.
By the way when you delete the table in Dev system then it will create one transport request and you just need to transport the request into the system from where you want to delete the table.

SLT Logging table issue

Hi,
We have configured SLT and was running fine. However, we found that some of the existing logging tables are created as a table in the configuration and that is in error (obviously).
Here is the screenshot:
The logging table for Table EKBZ is /1CADMC*637. Now the same logging tables has been created as Transp table and hence it is in error.
Did anybody come across such situation? Please help to resolve the same.

Hi,
have you been able to identify the cause of the issue and resolve it?
If yes, Can you share more details

Can we delete the change log table of ods?

hi bw gurus,
can we delete the newdata,active and change log table of ods?how?what is the advantage?
OR
can we delete the contents of new,active,change log table of ods?how?what is the advantag?
thanks in advance
srinivas

Hi Srinivas
Yes, You can delete the contents of changle log table but not the contents of new data and active data table.
Before deleting the change log data you have to make sure that the requests are not required for further delta extraction or for reconstruction purpose.
Steps
1. Goto Manage screen of your ods
2. Click on Environment tab and select the option " Delete change log data".
Adv:
To free up the disk space.
Assign points if it is useful for u.

How to find and remove obsolete table entries from /SAPAPO/MATKEY table in EWM System.

Hello,
How to find and remove obsolete table entries from below tables in EWM System.
/SAPAPO/MATKEY
/SAPAPO/MATMAP
/SAPAPO/MARM
/SAPAPO/MATLOC
/SAPAPO/MATMOD
/SAPAPO/MATRQ
/SAPAPO/MATLOTSZ
Thank you,
Pravin

Pravin,
First, tell me how you determine that these entries are 'obsolete'.
Removing master data from SCM can usually be done using transaction WUF; however, you have to ensure that it is not re-sent to the SCM system, or you are just wasting your time.

How to delete obsolete entries in SID table

I have an Infoobject (0PCA_ITEMNO) without master data and is used in a DSO. The sid table of the info object and its index has grown very large to about 207 gB. The DSO is periodically selectively deleted to hold the last 3 months data. How can I delete the the old and unused sid table entries to reduce the size.

Correct...you wouldn't want to delete the SID table values using custom code. This would potentially cause inconsistencies because you may inadvertently delete a SID value that is located elsewhere in your environment.
For example, if you have an InfoObject with SID value 1 for actual value of A1 and it's deleted. However, there is an InfoCube that has SID value 1 for this InfoObject in a dimension table.
To remove the values from the SID table for this InfoObject, your best bet is to use RSRV as stated before.

How to delete old logs in SAP BI, what is the best way to go?

Hi,
below are the issues we are facing,
when executing infopackage job is not getting triggred into source system.
for activation DSO data it is taking huge time. At the time of seqential read to RSREQDONE table.
I think this is due to huge logs in the staandard tables.
What could be the reson behind this.. and let me know how to delete old logs.
Thanks,
Harish

Hi,
just carry out RSRV for DSO PSA tables and see if there is inconsistency available there in the PSA table.
see if the change log and PSA deletion is happening regularly..else schedule same in PC
check with basis there are certain jobs which needs to run regularly at certain frequency..

Error when deleting a customer table

Hi guys, im deleting a Z table with a loop, and the following error is displayed after 10 minutes.
the log reads as follow.
1. ORACLE storage space request failed.
    (ORACLE error 1547)
To execute this operation, the ORACLE instance needs more
storage space for a segment. This storage is
managed by ORACLE in logical units known as extents.
The size of an extent depends on the segment definition and
the current storage situation.
One segment (possibly more) is stored in one tablespace.
The storage space available for a tablespace must be explicitly
preallocated by the database adminstrator. If, in course of time, the
volume of data in this tablespace increases considerably, the storage
space may be filled up (in real terms or through fragmentation).
2. Maximum number of extents reached for rollback segment.
    (ORACLE error 1556)
To execute this operation, the ORACLE instance needs more
storage space for a segment. This storage is
managed by ORACLE in logical units known as extents.
The size of an extent depends on the segment definition and
the current storage situation.
For each segment, the ORACLE instance can manage only a certain number
of extents. The maximum number for this
segment has been reached.
HERE THE CODE:
DO 48 TIMES. " HASTA 4 años.
DELETE FROM (p_ztable)
WHERE perio = periodo.
IF mes = '01' OR mes = '1'.
mes = 12.
anio = anio - 1.
ELSE.
mes = mes - 1.
ENDIF.
CONCATENATE ANIO '0' MES INTO PERIODO.
ENDDO.
any ideas?

Looks like the temporary memory pages are overflowed.
System hold the data in the temporary memory to enable ROLLBACK work.
So, we need to either do the COMMIT WORK or ROLLBACK WORK after cretain number of data.
Or, Reduce the number of loops and process smaller number of data at a time (before next COMMIT or ROLLBACK work).

Delete obsolete combinations in /SAPAPO/MC62 - how to use?

Hello SAP-experts,
We are using SAP APO Demand planning SAP SCM 7.0 with SP 15 for most of components.
I have some questions related to the button "delete obsolete combinations" in TA /SAPAPO/MC62. We want to use option "list combinations without planning data" to reduce CVC's quantity. What I have read it checks for CVC's without any entries at key figures. It sounds useful, but it doesn't seem to work in our company for some reason.
1. Where exactly does system check if there are key figures for the selected CVC's? In livecache directly? Or in an internal generated info cube for the planning area? Is it possible to view these key figures (on same base as done from system with option "list combinations without planning data") before using the deletion? Is there a report / table to do so? What's the best practise for this check (maybe on daily base)?
2. I have (some) CVC's without any key figure filled (for my opinion...). At the moment I check this with an info cube used for daily backup (means I see always the data from last night and I know that noone changed data because of blocked planning access). But it isn't found with "list combinations without planning data". When displaying the data in this backup-cube all key figures are shown as zero (the one which are shown for deletion and in same way the cvc's which are not shown). In the key figure settings "differentiation between zero and initial value" is not marked... I think this is correct, but maybe I have a misunderstanding here... any ideas about this setting? I don't believe this setting is wrong, because it shows me some CVC's to be deleted, but some of them are not shown (the setting should work for all cvc's in same way...?).
All ideas are most welcome, thank you all in advance!
Best regards
Harald Leissl

Hello Ali,
thank you for your reply!
My plan was to use standard tool, because it's available since some releases. I don't prefer to implement own programming instead of using an existing tool (talking about the built ABAP tool, the idea with alert makro sounds good).
Is the standard tool effective??? Good question. We talk about 2 steps.
If the mentioned function "delete obsolete" would work like designed (maybe it does, but I don't understand how...) it would do 2 steps combined:
- find out obsolete CVC's (your alert makro)
- delete obsolete CVC's (your ABAP tool)
Combining these 2 steps would be really effective, but it doesn't work for some reason. My estimation is that standard is not effective, because complete process of deletions of CVC's is very slow and causes sometimes performance trouble.
But this is the reason why I search for a standard tool to run periodically (maybe each week) for a check of "old" CVC's. I think our problem of slow running deletions is caused by too many CVC's in an planning object structure (together with the fact that our CVC's have a lot of key figures / characteristics).
To be honest my main task is to find the best possibility to delete a list of completely different CVC's (no unique selection possible). I tested a lot of things found in SCN (realignment, background deletion,...), but all the solutions have s lack in performance (at least in our system...).

Harald
