Issue with Delta Load in BI 7.0... Need resolution

Hi
I am having difficulty in Delta load which uses a Generic Extractor. The generic extractor is based on a view of two Tables. I use the system date to perform the delta load. If the system date increaes by a day, the load is expected to pick up the extra records. One of the tables used in the view for master data does not have the system date in it.
the data does not even come up to PSA. It keeps saying there are no records.... Is it because I loaded the data for yesterday and manually adding today's data...?
Not sure what is the cuase of delta failing....
Appreciate any suggestions to take care of the issue.
Thanks.... SMaa

Hi
The Generic DataSource supports following delta types:
1. Calender day
2. Numeric Pointer
3. Time stamp
Calday u2013 it is based on a calday, we can run delta only once per day that to at the end of the clock to minimize the missing of delta records.
Numeric pointer u2013 This type of delta is suitable only when we are extracting data from a table which supports only creation of new records / change of existing records.
It supports
Additive Delta: With delta type additive delta, the record to be loaded only returns the respective changes to key figures for key figures that can be aggregated. The extracted data is added in BI (Targets: DSO and InfoCube)
New status for changed records: With delta type new status for changed records, each of the records to be
loaded returns the new status for all key figures and characteristics. The values in BI are overwritten (Targets: DSO and Master Data)
Time stamp u2013 Using timestamp we can run delta multiple times per day but we need to use the safety lower limit and safety upper limit with minimum of 5 minutes.
As you specified, the DS is based on VIEW (of two tables, with one containing date and other does not).
Kindly check the above lines and verify, if the view (primary key) could be used to determine the Delta for your DS.
Also let us the if any standard SAP tables used in creating VIEW and if so, what is the size of the DS load every day?
Thanks.

Issue with delta load from R/3 to BW

Hi frnds,
There is a standarded D.S 2LIS_05_ITEM in R/3. Evereday We extraceted data from R/3 to BW based on this standard Data Source with delta load.There are two fields ZX and ZY in BW ,some times the data haven't extracted for this 2 fields in BW with the delta update.But some times this 2 fields properly extracted in to BW with the same delta update.
Why is it happen like this ? Please give some inputs on this.
Regards,
Satya.

Hello,
if its a standard field then its getting populated in correct way.
if its custom field then you need to analyze the records for which its getting populated and for one which its not.
Quite possible that some cutomization in CMOD results in this behaviour.
Also,check underlying tables to see the correct values.

Issues with Delta Loads.

Hi All,
I hope you don’t mind to provide a suggestion about the delta load of Purchase Orders.
There was a request from Procurement team and they complaint that the data is not looking right.
For example: for a given purchase order the exemption flag is displayed as ADE.
Before change:
Purchase Doc Number
Puchase Exemption flag
90002106
ADE
They want this to be displayed as:
After Change :
Purchase Doc Number
Puchase Exemption flag
90002106
So ABAPER has included the logic in ECC Functional Module to populate the Extract Structure for Data Source to display above result. But the overnight run didn’t pick up the changes to above record in BW. The loads are delta loads.
So my Question is:
· This load for the Infocube Purchase Orders is delta load. Does change to Function Module will pick up the changes to old records as well? I mean if we are doing delta load does the old records gets changed and updated in CUBE or should I delete the data from all the PSA and Infocube and run the load into CUBE to pick up the changes. Am bit worried about deleting the data from Infocube as it may have history data (because of delta load). Total records in cube are 800000 records.
· Another question does the process chain trigger the function module to load the data into Extract Structure of data source in ECC (am bit confused about this process in ECC)?
Please suggest me how can I capture those changed records?
Any help would be much appreciated. Please let me know if you need more info.
Thanks in advance
Sandeep

Hi Sandeep,
I am little confused from your post. You are using 2lis_02_SCL or the generic FM datasource?.
Also it looks like new custom field added in your client. I never saw any purchase exemption flag even though i am working in purchasing flow for last 2 years.
W.r.t purchasing , deletion flag will be there which will come from EKPO and have the values S or L ( Deleted or Blocked).
You can block or delete a PO aslong as GR was not happened. Other wise you can do it. So use the EKPO-LOEKZ for your use.

Problem with delta load urgent!!

Hi,
I have a problem with delta load
We have an IP, which loads data from R/3 system daily, its a delta load to the ODS and it updates to the cube with the selection on Company Codes and 0FISCPER
we are in 3.5 system
For a couple of company codes A & B, the init was done for the period 07.2010 to 12.2099 and after tht the deltas are loaded from 07.2010 till 12.2099 and there's no pblm with tht
Now, there was some updation in R/3 system and the data was maintained for the company codes in A& B for the FISCPER 001.2010 to 006.2010, for which init wasnt maintained...
now how shall we need to load the init in this case? dnt ask me how the postings was done in R/3, but my pblm is purely related to the loading data in BW from R/3, as its very imp for the customer to see the data from 01.2010 to 12.2010 in reports, but the data was only available in reports from 07.2010 onwards
do i need to create another IP and maintain the init for 01.2010 to 06.2010? so tht this selection will automatically appear in the ODS delta loading infopackage
pls throw ur inputs ASAP
thank you

Hi Prince,
No need to maintain any Init for this data, It will be enough if you can load the data from jan 2010 to jun 2010 into your Info Cube.
Follow the below steps:
1)create full load IP for this data source.
2) give the selection as A and B company codes and 0FISCPER as 001.2010 to 006.2010
3) in menu bar, click on scheduler --> select full repair request
4) In the next screen check the check box and save
5) Now execute the IP, it will the data with out disturbing your daily delta.
follow the same procedure to load data till to your Info Cube.
Please revert if you have any questions

Issue with site load time when exported as HTML. Addressed?

Has the issue with website load time been addressed?
I believe the site attempts to load the entire image content at the initial visit - meaning any galleries with numerous pictures are all included when first getting to the site. This is causing a HUGE increase in load time. I was told when I last brought it up that it was an apparent issue that needed to be addressed.
Any type of resolution coming?
Site for reference: www.dkrecollection.com

Major updates of Muse are targeted to release roughly every quarter. The 1.0 release was in mid-May. The 2.0 release was in mid-August. A fundamental change to image loading would only appear as part of a major update due to the engineering and testing efforts required.
As provided in your previous thread http://forums.adobe.com/message/4659347#4659347 the only workaround until then is to reduce the number of images in the slideshow.

Issue with Delta Request

Hi Friends,
I have an issue with loading.
1. From source 2lis_13_VDITM, data loads to 2 targets.
ZIC_SEG, 0SD_C03.and from 0sd_C03 it again loads to ZSD_C03W and ZSD_C03M through DTP.
I have done a repair full load on 08.08.2011 to PSA and loaded this request manually to cube ZIC_seg.
I forgoted to delete this request in PSA as i dont want to load this to other targets.
Before i notice ,already delta requests got loaded and has pulled my repair full request also to other targets.
As i have not done any selective deltions on other cubes there may be double entries.
I am planning to do the below steps inorder to rectify the issue.
1. Do a selective deletion of the delta request in all 3 targets which got loaded on 8th along with repair full.
2. Delete the repair full request from PSA.
So now delta request which got loaded after repair full request, is left in PSA.
My question is if my PC runs today will this delta request in PSA also pulls again to cube through DTP?
Kindly share any other ideas please urgent...
Regards,
Banu

Hi Banu,
If the data in the CUBE's is not compressed, then follow the below steps
1)Delete the latest request in CUBE ZIC_SEG
2)Delete the latest request from cubes ZSD_C03W and ZSD_C03M and then from 0SD_C03.
3)load the delta request manually using DTP from your cubes(in DTP you can load by giving request number). to cubes ZIC_SEG and 0SD_C03.
3)now run the delta DTP to load the delta request from 0SD_C03 to ZSD_C03W and ZSD_C03M.
Next when your PC runs it will load only that particular day delta request.
It will work

Master data is getting overwrite with delta load

Hi,
We have an issue like some some asset numbers are showing blank for wbs elemnts.So we did Full repair Request.So pblm is solved.But after daily delta loads it is getting over write and again asset numbers are blank..please let me know any suggestions?
Regards,
Baanu

Ok, so your problem in the source-system itself. Since the update mode for master data is overwrite, when these records with blank fields are loaded they will replace the existing values and you will have blank values in your master data.
Check whether the data is available in the tables in the Source-system. If you have made any enhancements to the DataSource using exits, check the code for the exit and try to find out if the data is being changed by the code.
If there are no enhancements, check whether the master data is being properly maintained in the source system.

Hi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

Issue with a load from R3 to BW 3.5

Hi Guys,
We are having an issue here with a load from R3 to BW 3.5 to an ODS and
a transactional infocube.
In a daily basis we are running loads to BW from R/3 infosets and all
of them but one loads fine.
The one that is having problems is actually the one that loads more
data, therefore the infopackage is divided into two infopackages.
In the update rule of the first ODS we are running an initial routine
in which we are doing a RSDRD_SEL_DELETION (selective deletion) of the
data to be loaded to both the ODS and the infocube, and is actually
here where we got the core dump.
Our first assumption was that maybe there was any yellow request in the
transactional infocube avoiding the selective deletion but we have
discarded this.
We think that, as the only one failing is the one that divides into two
infopackages, the problem might be that at the moment that the first is
triying to delete the second one is loading data into the ods and there
we get the dump.
The question here is ¿Could this be the problem? ¿How could we
workaround this if this is the case?
Thanks for any suggestion.

Hi,
Be carefull on ODS activation, if you're using 2 infopackage and/or deleting data from an ODS which is lock for an activation, you'll occurs a dump.
Check SM12 / ST22 / SM21 and job logs in SM37.
And if pb still occurs for a load, debug it in start routine.

Did this resolve my Safari 5 issue with not loading pages as fast?

I've been having this problem every since I got my laptop a month ago... I have a wireless router that's connected to a PC, and I use wireless on my laptop. My old laptop was a PC, and the internet connection was just fine on it. However, I'm having issues with my MacBook Pro. When I first turned on my laptop after taking it out of the box, Airport detected my wireless router and connected me to the internet. Obviously, I used Safari 5 as my browser and although it works... it doesn't load the pages as fast as it should. It even stops loading at times. Usually, I quit Safari and reopen Safari and it works and if it doesn't, I click on the reload button or just keep re-opening Safari until it does work... buttt I am tired of doing that now. So after a lot of attempts by trial and error, I think I found the solution and was wondering if anyone could confirm this with me. I went to my router's IP address and I looked at the settings. I looked at the router's DNS settings and I copied and pasted that router setting into the DNS settings on my laptop for the wireless network. Now, my internet seems to be working... but then again it has only been 5 minutes. So my question is... the router's DNS has to match the wireless network's DNS address?
Sorry if this sounds like a stupid question... I'm not an expert when it comes to internet, LAN, proxies, and etc. settings. Thank you!

Further investigation has revealed that the following error message is being generated within Safari during the first time the that the page is loading,
"Refused to load from document base URL. URL found within request."
The <base> directive in the HTML, in this instance, is referring to a different URL than the one that the page is running from. The page with the problem is running on a remote server and back referencing to the home server for the <base> reference. This fails when the page first loads but seems to be accepted if a page-reload is done. It also works on all other browsers that have been tested.
Is this related to a security setting in the browser?

Having An Issue With Site Loading In Firebox

Hello,
I'm having a small issue that I could use some help with. I'm not really sure what is going on, but I'm having an issue with one of the pages from my site not loading when trying to view the page in Firefox. But if I load this page in Safari or Chrome, it loads just fine.
Here's the page URL to take a look: 
Specific link removed from display by moderator ~J99 <sitename>.com/top-10/top...services/

Any idea on why this could be happening or how to fix it? I'm not sure if it's just my computer, or if others are having the same issue.
Thanks in advance,
Mike

Hello Mike,
I have no problem loading and seeing the page <site>.com/top-10/...monitoring-services . General advice would be to try clearing cache and site cookies on the machine you are using.
*see [[Firefox can't load websites but other browsers can]]
I imagine you will have easy access to other machines on which you can test with Firefox so hopefully you will be able to test and demonstrate that the page does normally load on Firefox.
Website design is outside the scope of this forum, but you probably have a professional team working on that.
