Historical Data Maintenance

Dear Members,
This is my second post in the forum. Let me explain the scenario first,
"We have 2 Tools -Tool1 and Tool2 which points to 2 different databases - db1 and db2 respectively. currently, the db1 performance is very poor due to huge data. we want to have only latest 18 months data in db1. The oldest data beyond 18 months should remain in db2 (in read only mode)which Tool 2 connects to. So, whenever i need historical data, i`ll use tool2. At regular intervals the data from db1 should move to db2."
My idea is to use partitioning and logical standby. At the end of each month, the oldest one month data will be moved to db2. But please let me know whether this will be feasible to the above concept. If so, how to implement this and if not, what would be the right solution for this?

Partitioning is great on the source side (assuming you partition by date, of course).
I am not sure how logical standby would help on the destination. The point of logical standby is to keep the standby database up to date with the primary, so the standby database would not be read only, it would be constantly applying transactions from the primary. And when you drop a partition on the primary, you would drop the partition on the standby, so the standby wouldn't maintain history.
Instead of logical standby, you could use Streams to replicate transactions and configure Streams to ignore certain DDL operations like partition drops. That would allow you to retain history on db2 but wouldn't give you a read-only db2 database.
You could potentially do partition exchange in db1 at a regular interval, moving the data you want to remove into a non-partitioned staging table, move that table to db2 (via export/import, transportable tablespaces, etc), and do a partition exchange to load the data into the partitioned table on db2. That gives you a read only db2 and lets you retain history, but requires some work to move the data around every month.
Of course, if you decide to partition db1, assuming you did it correctly, I would tend to expect that the performance problems would go away (or at least that archiving the old data wouldn't affect performance any longer). One of the points of partitioning is that Oracle can then do partition elimination for your queries so that it only needs to look at the current partition if that's all tool1 is interested in. So perhaps all you need to do is partition db1 and you don't need db2 at all.

How to populate historical data in the appraisal

Hello,
I am working in Oracle PMS module. Our requirement is to display historical data of an employee in the next appraisal cycle.
Eg. If there are 3 appraisal cycle in a year. In the first appraisal manager will add objectives and competencies for an employee. lets say he added competency 1 ,competency 2,Objective 1 and Objective 2. after completion of the first cycle.
When manager initiates the second appraisal. in the objectives block 2 values (Objective 1 and Objective 2) should be auto populated. Same as in competency block 2 values (competency 1 and competency 2) should be auto populated.
Here manager can add more objectives or competencies.
Please suggest how this can be achived.
Thanks in advance,

Hi Shunhui
Answers :-
If the required fields are not available in the Maintenance link, does it mean that I have to goto SE11 and create an append structure for the extract structure MC02M_0ITM which belongs to the datasource 2LIS_02_ITM?
Then I have to write codes in the user exit for transactional datasources in RSAP0001?
Ans : That's correct . Once you have done this on R/3 side, replicate the data source in BW side. Activate the transfer rules with appropriate mapping for 3 new fields and also adjust the update rules so that these 3 new fields are availble in Info providers.
Are you able to provide some information on the errors that might arise during transports with the delta being active in the production system? Will data be corrupted? Will I need to clear the delta queue before the transport goes over?
Ans : I assume that deltas are active in Production system . There is risk to your active delta into BW .
Before your R/3 transports reach Production system , you need to clear the delta queue that means bring the number of LUWs for 2LIS_02_ITM to zero . Also stop the delta collector job in R/3 for Application 02(purchasing). Make sure that there are no postings (transactions /users are locked) so that there will be change in purchsing base tables.
Then send your R/3 transport into Production system (Append structure , new fields + user exit code) .Replicate on BW side. Now send the BW transports to BW production system .
I had done this earlier for 2LIS_12_VCITM and had a step by step proceduew written with me ....will have to search for that document . Let me know your email ID , will try to send it once I find the document

CSR Historical Data not capturing data?

Hi All,
Last week (on Thursday) our Historical Data stopped capturing any details?
I have captured a screen shot of the report. You can see that the agent logged in time is 111:47:23 (at 3:47:23pm EST). Any help fixing the issue would be greatly appreciated!
Thanks in advance!
Craig

Hi Craig,
Subscriber Goes Down
When the subscriber goes down for more than the 2- or 4-day retention period,
reinitialize the subscriber in CRS Administration (Datastore Control Center web
page) and reinitialize the subscription for all the datastores.
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_5_0/maintenance/admin/crs501ag.pdf
Access the Datastore Control Center by selecting System > Datastore Control
Center from the CRS Administration menu bar.
Reinit Subscriber—Click this button to reinitialize the subscriber with a
copy of data from the Publisher. (This causes the data on the subscriber to be
overwritten by the data from the Publisher.)
Note Only use this button if you have determined that the Subscriber needs this
data from the Publisher (if the Subscriber and the Publisher are not
synchronized).
Hope this helps.

Best way to store historical data

Hello:
I'm currently developing an application that monitors some phisycal
variables such as temperature and differential pressure in different
locations. I also must do historical datalogging of the values read so
the user can generate reports of the historical data. What is the best
way to save the data? I was thinking about using and SQL-based database
and use a table for each variable, an make some maintenance on the
database after certain time to avoid it getting too big, but I'm opened
to any suggestions

MP31 - no historical data - how to generate?

Hi specialists,
Mi problem: I have several materials, for which I cannot execute a forecast, because there is "no historical data". The material is very old and there was for sure consumption on it in the past, but before this material was never under MRP.
Is there a way to generate this historical data automatically, maybe even in mass? or do I really have to do that manually material by material?
Any help is appreciated.
Tnx a lot
Kurt

Hi Kurt,
Historical consumption data gathering in the system is not dependent on the material being MRP or not, but on the definitions per movement type, and maintenance of period in one of the plant level views of material master.
I don't know of any procedure in standard SAP that will "rebuild" consumption data. Neverheless, you can always enter your "corrected" historical data, and it will be used by the system for forecasting.
You can do it manually for each material, or upload it from an external file.

SCEP Historical Data

1. Are SCEP Historical Data (Threat History) stored on a log on the Server? or does SCCM 2012 read the data from the SCEP Logs on the client?
2. If I'm looking to keep\pull SCEP historical data for 1 year, do I have to edit the "Delete Aged Threat Data" under maintenance task from the default "30" days to "365"?
Just seems strange that the default is 30 days. I know Auditors require tracking historical data from a year or so.
Andrew Marcos

Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?
No There will be no problem doing this except for there will be an increase in the database size.

Upload Sales Historical Data in R/3?

Hi Guys:
We are planning to use forecased based planning MRP Procedure ( MRP Type VV ) for Material Planning , we need historical sales data to execute the forecast.
can anybody tell me step by step how to upload 12 months historical data into SAP R/3, so that we can excute forecast based planning for a material?
Thanks
Sweth
Edited by: Csaba Szommer on May 12, 2011 9:57 AM

i need to to pull data in bw from r/3 for frieght rates
example for rate is from source to dest(in rows) and on the basis of this we have counditon types(in columns) which we will put in coloums and on the base of those cound type we will get cummulated value of master data rate.
like
source dest rate(based on coundition types)
now in r/3 some coundition type are changed to new ones or we can say merged to new ones, now my question for new one i can pull no problem but what i'll do for the historical master data like coundition type in 2006 are diff and 2007 is diff
but they mapped in each othe

Upload of historical data from legacy system

Dear forum
We are running standard SOP with transaction MC88 in ECC6.0.
We are doing forecasting on material/plant level, based on historical data (we create the sales plan from transaction MC88).
Now, the problem is that we are introducing new products into SOP, but there is no historical data in SAP for those materials.
Is there any way we can import historical data into SAP from legacy system, so that SOP would take this data into account when calculating the forecast?
Note: we do not want to build anything in flexible planning. Just want to check whether or not it is possible to import historical values from a legacy system, to use as historical data in SAP.
Thanks in advance
Lars

Thanks,
But that will not help us.
Any ohter suggestions out there?

How to get Historic Data in Oracle

Hi,
THe following query might be useful to generate the consecutive dates from given date to sysdate.
SELECT dt
FROM ( SELECT to_date('02/19/1981','mm/dd/yyyy')+rownum-1 AS dt
 FROM user_objects
WHERE TRUNC(dt)<=TRUNC(SYSDATE);NOw lets consider the basic scott.emp table
The above requirement can be acheived using this query as we may get only 14 records as there are only 14 records in scott.emp table
select ( to_date('02/19/1981','mm/dd/yyyy')+rownum-1) as dt
from scott.emp If we see the scott.emp table there are 2 reocrds with empno 7499,7521 with hiredates 20-feb-81 and 22-feb-81 respectively. on pulling the historic data from19-feb-81 to 04-mar-81 as there are only 14 records in the table we need to get the sum of sal or comm as it is along with those dates in the table.
Assuming there are more than one record for the same date for the dates mentioned above , i have used the following query but could not get the desired output.
Select To_Date('02/19/1981','mm/dd/yyyy')+Rownum-1,
sum(Case When Sal>0 And Trunc(Hiredate)= (To_Date('02/19/1981','mm/dd/yyyy')+Rownum-1)
Then (Sal)

Else 0 End) As hist_comm
From Scott.Emp
Group By To_Date('02/19/1981','mm/dd/yyyy')+Rownum-1

Unless you're using Oracle 8 (or older) then it's more efficient to say:
SELECT start_dt + LEVEL - 1 AS dt
FROM (
 SELECT TO_DATE ('02/19/1981', 'MM/DD/YYYY') AS start_dt
 , TRUNC (SYSDATE) AS end_dt
 FROM dual
CONNECT BY LEVEL <= 1 + (end_dt - start_dt)
;and it doesn't depend on how many rows happen to be in user_objects.

Do you want to know if there's a simpler and/or more efficient way to get the same results as the 2nd query you posted above?
Here's one way:
WITH all_dates AS
 SELECT start_dt + LEVEL - 1 AS dt
 FROM (
 SELECT TO_DATE ('02/19/1981', 'MM/DD/YYYY') AS start_dt
 , TO_DATE ('10/31/2012', 'MM/DD/YYYY') AS end_dt
 FROM dual
 CONNECT BY LEVEL <= 1 + (end_dt - start_dt)
SELECT TO_CHAR (a.dt, 'Day, Mon DD, YYYY') AS business_date
, SUM (e.sal) AS hist_sal
FROM all_dates a
LEFT OUTER JOIN scott.emp e ON e.hiredate = a.dt
GROUP BY a.dt
ORDER BY a.dt
;For testing purposes, it would be a lot clearer if you made the end_dt something like April 5, 1981 rather than October 31, 2012.
I hope this answers your question.
If not, post the results you want from the data in scott.emp, given some reasonable date range. (I suggest Nov. 16, 1981 through Jan. 24, 1982; that includes December 3, 1981 which has 2 rows with the same hiredate.)
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Remote historical data is not retrieved completely viewing it in MAX4

Hi,
since I installed LabVIEW 8 I have some problems retrieving historical data from another computer. Sometimes not all data is retrieved (if I zoom in or out or move back in time) and this missing data won't be retrieved ever.
I already deleted the Citadel cache once, but after this even less data was retrieved... What's really weird, is, that for channels which weren't retrieved correctly, the data gets not updated anymore!
On the remote computer I have a LabVIEW DSC Runtime 7.1 running (MAX 3.1.1.3003) on my local computer MAX 4.0.0.3010 and LabVIEW 8 DSC (development system) is installed parallel to LV DSC 7.1.1 (dev system). LV 8 is installed for testing purposes (I doubt we'll switch soon) and overall I like MAX 4. The HyperTrend.dll on my local computer is version 3.2.1017.
This is really a quite annoying bug!
So long,
Carsten

Hi,
> We've been unable to reproduce this issue. If you could provide some additional information, it might help us out.
I did fear this, as even on my computer it is happening just sometimes...
> 1) How many traces are you viewing?
The views I observed this in had 2 to 13 traces.
> 2) How often are the traces being updated?
For some it's pretty often (about once a second), for some it's very infrequent (no change in data, that means updated because of max time between logs). I more often see this for traces that are updated very infrequently. But I think I've seen this for frequent traces as well (for these it does work currently).
> 3) Are the traces being updated by a tag value change, or by the "maximum time between logs" setting in the engine?
It happened for both types.
> 4) What is the frequency of the "maximum time between logs" setting?
Max time between logs is 10 minutes.
> 5) Is the Hypertrend running in live mode when you zoom out/pan?
I think it happened in both modes, but it defenitely did in live mode.
> 6) If you disable/re-enable live mode in the Hypertrend, does the data re-appear?
I couldn't trigger the loading of the data. All I did is wait and work with MAX (zooming, panning, looking at data) and after quite a while (some hours), the data appeared.
Just tested this on a view where data is missing (for some days now!), and it didn't trigger data reloading. Zooming and panning don't as well. There's a gap of up to 3 days now for some traces. 7 of the 13 traces of this view are incompletely shown. All stopping at the same time but reappearing at different ones.
AFAIR from the laboratory computer (these are temperatures and it's very plausable that these didn't change), there wasn't any change in these traces so they all got logged because of max time...
I just created a new view and added these traces: the gap is there as well.
(Sorry to put this all in this entry even if it is related to you other questions, but I started this live test with disable/re-enable live mode. )
> 7)
Are the clocks on the client and server computers synchronized? If not
synchronized, how far apart are the times on the two computers?
They should be (Windows 2000 Domain synchronized to ADS), but are 5 seconds apart.
One thing I remember now: I have installed DIAdem 10 beta 2 (10.0.0b2530, USI + DataFinder 1.3.0.2526). There I had (and reported) some problems with data loading from a Citadel Database of a remote machine as well. This was accounted to some cache problem. Maybe a component is interfering?
Thanks for investigating.

Carsten

How to extract the historical data from R/3

hi
I am extracting data from R/3 through LO Extraction. client asked me to enhance the data source by adding field. i have enhanced the field and wrote exit to populate the data for that field.
how to extract the historical data into BI for the enhanced field. already delta load is running in BI.
regards

Hi Satish,
As per SAP Standard also the best way is to delete whole data from the cube and then load the data from set up tables as you have enhanced the data source.
After data source enhancement it is supported to load normally because you don't get any historical data for that field.
Best way is to take down time from the users, normally we do in weekends/non-business hours.
Then fill the set-up tables; if the data is of huge volume you can adopt parallel mechanism like:
1. Load set-up tables by yearly basis as a background job.
2. Load set-up tables by yearly basis with posting periods from jan 1st to 31st dec of any year basis as a background job.
This can make your self easier and faster for load of set-up tables. After filling up set-up tables. You can unlock all users as there is no worries of postings.
Then after you can load all the data into BI first into PSA and then into Cube.

Ravi Kanth.

How to see the historic data of CAT2

Dear All,
I have a question related to CATS.
Through which table I can get the historical data of an employee which is stored in CAT2 transaction. I tried through CATSDB but not able to get the number of working hours as stored in CAT2.
I clied on a field of CAT2 and checked the technical details. there I found the table name CATD but when I run SE11 and enter this table name, it display it as a sturcture not as a table.
Please provide your help in this regard.
Regards,
-Neha

Maximum NUmber of Columns allowed is 1023. So if there are more data than that, I am afraid there is no way to see them all in one screen.
the better thing to do is to use the Settings>Format List>Choose fields option from the selection screen of SE16 to just choose the fields which you want in the output.
It is highly unlikely that you are using all the 100 fields so you can very well hide a few of them with no impact on your output.
As someone else has suggested using a report such as CATSXT_DA will defintiely be a much more useful way of viewing all relevant fields from CATSDB.

0HR_PT_2 How to get back historical data for new report time type

Hi All Expert,
We have implemented and using the 0HR_PT_2 extractor for the past whole year. The Delta is working. Recently, there is requirement to read more data from the ZL custer table, and more new BW Report Time Types are added to extract such data.
The delta doesn't pick up the the past whole year data of the new report time type that we added.
Do we need to re-initialize the load to get back those historical data every time when we add a new report time type?
Please advice and Thx
