Using Transformations with Delta enabled Datasources

Hi,
I have a delta enables datasource which uses incremental update to my infoCube.
In order to populate some fields in the cube I used a transformation routine for a couple of these fields to do some lookups from some tables.
The problem that I am encountering is that when the delta update runs its only updates the directly assigned fields it does not also update the routine delivered fields.
Is there a way to get this to work or is it impossible?
Thanks

HI,
The routines work fine for full load as the data is replaced with new data each time.
What I need to happen is I am using a SAP standard content datasource with delta enabled on the datasource and when loading from datasource to Cube all the 0 fields are updating correctly but my Z fields which i update with routines do not seem to be replaced.
Please advise of anyway to get this to work
Thanks

Generic Delta enabled datasource with Functional Module

Hi All,
We have a requirement to create a Generic Data Source which will be having fields from the tables COEP, COBK & BKPF. Generic datasource should be delta enabled. We are planning to achive it by writing a Functional Module.
No my question is can i use BWFI_AEDAT & BWOM2_TIMEST tables to make Generic Datasource delta enabled. If i can then please let me know how. If i can't then please let me know what should i do to make it delta enabled.
Thanks & Kind REgards,

Generic Extractor using FM with Delta Logic

Hi,
i want to create a generic extractor with Delta Logic based on a FM.
The extractor works fine for full loads (extractor method "F" or "C"), but delivers no record for the extractor method "D" (Delta). I placed a hard coded break-point in the FM, so that the processing should stop while testing it with TC "rsa3". Using the extractor method "D" the debugger doesn't stop. So it seems, that this FM will not be processed for method "D". What could be wrong?
I tried different ways to create the generic extractor:
First i copied the template "RSAX_BIW_GET_DATA_SIMPLE" and tried to get the information for delta-run by "LOOP AT i_t_select INTO l_s_select WHERE fieldnm = 'DATE_FIELD'." But as the processing for method "D" does not consider the FM, there is no chance to get delta data.
On second try i used the template "RSAX_BIW_GET_DATA" and changed "EXMETHOD" from "F1" to "F2" in table ROOSOURCE for the Data Source. In this case i get information about the Update mode (Parameter i_updmode). But the processing leaves the FM for extractor method "D" out too.
Does anybody know, why the FM is not processed for extractor method "D"?
Is there another way to get delta capable extractors based on FMs?
Thanks for help in advance!

Drawing Markup and Annotations using Reader with Commenting-Enabled PDFs

I recently purchased Acrobat Standard to produce commentable PDFs for my contributors who use Acrobat Reader.
The page linked below says that I can use Acrobat Standard to "Manage shared reviews, collecting everyone's feedback in one PDF and letting reviewers build on one another's comments‡"
Adobe Acrobat XI
I have used these features in the past with Acrobat Pro, but there wasn't any documentation that hinted at what appear to be limitations. For example, using Acrobat Standard I can send a PDF for email review, but the only tools that my contributors can use with Reader are the sticky note and highlighter. In the past, when I used Pro, the whole suite of markup capabilities including Drawing Markup and annotations like strikethrough were available.
I have looked everywhere for information about how to enable these other commenting tools, but can't find anything. Am I missing something or is this some misleading marketing materials that have led me astray.

You either need to upgrade to Acrobat Pro or the users need to upgrade to
Reader XI, where all of the commenting tools are available by default.

Delta enabled generic data source not generating delta

Hi Experts,
I am simply clueless bt where I went wrong.Please have a look and explain.
I first created a z table in r\3 with one field as timestamp.
Then I created a delta enabled datasource for this table, in the delta enabled field I selected Timestamp.
Safety interval left blank.
Delta was chosen as "ADDITIVE DELTA".
After that I saved my data source and replicated the same in BI server.
Then I created an Infopackage to initialize the delta and then one more infopackege was created as delta .
Initialization was successfull.
Now I triggered the delta infopackage to bring delta to PSA
BUT
it does not bring the delta ,rather each time it brings in ALL records to PSA . This is the problem m facing .
PLEASE EXPLAIN ME IF YOU CAUGHT ANY MISTAKE IN THE ABOVE FOLLOWED STEPS.
waiting for reply
Manish Sharma

Hi Teja,
Thanks for your reply, I checked the same .
The initstate field has the value 'X'.
I checked in RSA3 but upon test extraction it says 0 records selected.
Pls investigate more on this.

Looks like the link you originally clicked was a scam to get you to submit your username and password. I reckon the email from Google was legit (because it did not ask you to enter your username and password, but advised you to change your password.) So it looks like they did actually block a sign-in attempt. Sometimes, scammers do send out emails like this, but they are the ones which ask you to sign in again (because it's those details they are after).
Given that you've changed your password three times you should be safe. The golden rule is never submit usernames and passwords when prompted from an email - it's almost certainly a phishing attempt designed to get hold of your details.

Photoshop CS5 with OpenGL enabled runs incredibly slow

My system specs
MacBook Pro 17"
OSX 10.6.3
3.06GHz Core 2 Duo
4 GB 1067 MHz DDR4
NVIDIA GeForce 9400M/9600M GT
CS4 is installed as well
Photoshop settings
Not using Application Frame
Not using tabs
With OpenGL enabled in either Basic, Normal or Advanced mode, the whole experience is much slower.
The Marquee selection tool is laggy. I move the cursor around quickly while selecting and the selection area can't keep up.
Resizing the document window is laggy. Like the Marquee selection, it can't keep up with my cursor.
Paintbrush tool outline is slow to enlarge.
I'm sure there's more, but that's all I've noticed. When I have GPU disabled, Photoshop runs like butter.

It does it in both graphic modes.
But I figured out what the problem was...
Vertical Sync!
I had it enabled. When disabled, Photoshop runs smooth as butter.

Is it just me or does Exchange with Push enabled drain the battery?

+*I'm pretty sure that this is obvious to all - I just don't see how everyone is just okay with it.+*
The iPhone battery is generally very good; even when using MobileMe with Push enabled, etc.
BUT; once you add a Microsoft Exchange account & leave Push enabled, you could probably watch the battery drain like a sewer right after a heavy rain storm.
Personally, I keep my Exchange on Fetch every 15 minutes and this provides an enormous difference in battery performance.
*_Why is everyone just okay with this?_*
+Just to explain my theory+ - if you watch the background activity using XCODE's Console, it's a pretty dead giveaway. Microsoft Exchange with Push enabled is not really utilizing the true 'push' technology; rather, it's actually checking in and pinging the corporate exchange server every 7-10 seconds. This allows the device to maintain the 'push' image of receiving an email in 'realtime'. But all of this is at the tremendous cost of the battery life. Personally, when I leave my Push on, I need to charge my iPhone 2-3 times daily vs. once every other day with Fetch.
+Comments, anyone?+

OK, what you are seeing is a problem with your phone, not a general problem with the iPhone or any specific release. Most of the time my phone gets excellent battery life with Exchange Push enabled. Occasionally (a couple of times a year) I suddenly see a heavy battery drain with Push on. I've seen it with every release of iPhone software since Activesync was added. I've concluded that something is broken when this happens. An IT admin in the forum posted about a year ago that he saw many open connections to phones of users when they were reporting this problem. He rebooted the Exchange server and the problem went away for a while. As most of us don't have that option I've found a couple of ways to fix it on the phone. One or more of them has always worked for me.
1. Reset Network Settings on the phone and reboot.
2. Go into Mail,Contacts,Calendar, tap on the Exchange account and turn off all 3 functions. Then reboot, go back and turn them on.
If these don't fix it what I do is go into Settings again and delete the Exchange account. I then reboot and add it back. I then wait several hours for the account to resync (it's best to do this with a WiFi connection). When all of my email, contacts and calendar entries have reappeared I fully charge the phone and test battery life again. This sequence has always worked for me, but I have seen posts from owners who say it did not work. But most say it works.

How to do Delta upload and consolidate in SSM, how to use transformer.ini

Hi,
Can anybody explain me how to do Delta data upload and also how to do delta data consolidation in SAP SSM.
Also how can i create and use transformer.ini file.
Thanks and reagrds
Edited by: Himanshu Bisla on Mar 25, 2009 2:09 PM

Hi,
Where from are you planning to upload data?
When you mention a delta upload, does it mean loading new data for a new PERIOD, where no data yet existed, or loading values to measures for periods where data already exists, doing a SUM?
When loading from an external source, you use a READ command, which by default replaces existing values with those that are being loaded. If you add the parameter ADD or SUBTRACT to that IDQL command you are able to change this default behaviour to enable delta loads (with SUM or SUBTRACTION operations).
As for the CONSOLIDATIONS, you can define a date range for the consolidation, or run it for a single period (month, quarter) if needed, or restrict the number of measures you want to consolidate. There is no way to automatically define that only the measures and periods that have new data will be consolidated. This has to be made explicit in the CONSOLIDATE instruction.
Regarding the Transformer.ini, are you planning to use PAS as an ETL tool? Unfortunately, I can only point you to the information that is available on the PAS Help, but that's probably where you found the reference to this function in the first place...
Hope this helps!
Best regards,
Ricardo

Standard datasource do not work with Delta DTP

Hi,
0MAT_PLANT datasource is connected to an infoobject and a datastore
object. The DTP into the infoobject manage the delta but the delta dtp is not supported for the Datastore transformation.
The following message occure:
"Update mode 'Construct Opening Status' is usually not permitted for updating a DataStore object. With the update modes 'Initialization of the Delta Process', and 'Delta Update', whether an update to a DataStore object update is permitted depends on the delta process,."
When i create a specific extractor i do not face the problem.
Is it possible to use delta DTP to populate datastore with datasource using E delta process?
thanks for your help,

Hi Viermont,
Did you check the OSS Note: 973475 - No delta extraction for materials in ODS object
Symptom
During the delta extraction of data for the following DataSources, the system issues error message RSM1 113 ('Cannot update DataSource &1 to a DataStore object').
0MATERIAL_ATTR
0ARTICLE_ATTR
0MAT_PLANT_ATTR
0ART_PLANT_ATTR
0MAT_SALES_ATTR
0ART_SALES_ATTR
0MAT_ST_LOC_ATTR
0ART_ST_LOC_ATTR
In update mode, you want to update the DataSources with delta procedure E to an ODS object as the data target.
Other terms
RSM1 113, RSM1113, RSM1(113), ODS, delta procedure E, roosource
Reason and Prerequisites
The ODS object update is not permitted with delta procedure E for the 'Initialization of the delta method' and 'Delta update' update modes .
Solution
Carry out the following steps for the 0MAT_PLANT_ATTR or 0ART_PLANT_ATTR DataSources (for customers using the industry solution retail).
Carry out the same steps for the other DataSources, but use the following program in step 1:
0MATERIAL_ATTR or 0ARTICLE_ATTR --> Z0MATERIAL_ATTR_UPDATE
0MAT_SALES_ATTR or 0ART_SALES_ATTR --> Z0MAT_SALES_ATTR_UPDATE
0MAT_ST_LOC_ATTR or 0ART_ST_LOC_ATTR --> Z0MAT_ST_LOC_ATTR_UPDATE
1. Implement the attached Z0MAT_PLANT_ATTR_UPDATE program and execute it in your OLTP system.
2. Use transaction RSA5 to activate the 0MAT_PLANT_ATTR or 0ART_PLANT_ATTR DataSource in your OLTP system. Open the following nodes:
SAP-R/3 -> LO -> LO-IO
Select the 0MAT_PLANT_ATTR or 0ART_PLANT_ATTR DataSource and choose 'Activate DataSources'.
3. You can use transaction RSA2 to check the 0MAT_PLANT_ATTR or 0ART_PLANT_ATTR DataSource. The delta procedure should be NEWE.
4. Replicate the DataSource in the BW system.
To do this, call the Administrator Workbench in the BW system and display the DataSources for the relevant source system. Find the DataSource in the DataSource overview and replicate it.
Bye

Not able to Check Delta Enabled Checkbox in Datasource

Hi,
I created a Custom Datasource in ECC system which extracts data through Function module. I activated the Datasource without checking the Delta checkbox. Only when i created Infopackage in BI, i realized my mistake. When i try to go back to ECC system, i could see that the Delta Enabled check box is now disabled, i am not able to check it now.
Is there any way i can make this datasource to Delta enabled in ECC system now?
Regards,
Murali

yes Murali you need to maintain the delta in RSO2.
select radio button -timestamp local and enter your field:AEDAT.
check the upper limit n lower limit with functional team so that you do not miss any delta records.
Check the below link for more detail

2 transformation with same datasource

Hi
Can I assign one Datasource to 2 DSO . I want to create a transformation . I hv already creatred one transformation with one DSO and by using the DS , I am creating a transformation with other DSO . getting msg that , DS is not active .
Is it possible to create 2 transformation by using the same DS with different target .
Regards

HI Maasum
Yes, you can make the same datasource point to two different data targets. As you've alreadt mentioned you would need to create two independant transformations. Be sure to replicate the datasource and activate the transformations before testing the data load.
Hope this helps.
Thanks.

Generic datasource delta enabling against S973 & S966

hellow gurus
m workin on BW 3.5
i have to create Generic datasource for Warrqanty FOC against Sales
for that i need to create a datasource using S966 and S973 View
could u plzz tel me
on which field should i make Delta enable in generic Datasource and
what shuld i selc in DATA-Specific Field -
and which radio button
Time Stamp
or Cal Day or Numeric Pointer
and
Saftety interval upper and lower limit for the same.
points will be awarded as my gesture and thanks for ur efforts
regards

Hi,
The following is the criteria that needs to be looked upon during Delta enabling in Generic Datasource.
Delta Specific Field :
Time Stamp - If you are extracting data for critical modules like FICO, go for Time stamp.
Calendar Day - If data is extracted from modules that does not have huge postings in a day, like Sales or Delivery Billing, go for Calendar day.
Numeric Pointer - For sequentially generated records like GLPCA, go for Numeric Pointer.
Safety Interval (Upper & Lower Limits) :
(1) If delta field is Date (Record Create Date or change date), then use Upper Limit of 1 day.This will load Delta in BW as of yesterday. Leave Lower limit blank.
(2) If delta field is Time Stamp, then use Upper Limit of equal to 1800 Seconds (30 minutes). This will load Delta in BW as of 30 minutes old. Leave Lower limit blank.
(3) If delta field is a Numeric Pointer i.e. generated record # like in GLPCA table, then use Lower Limit. Use count 10-100. Leave upper limit blank. If value 10 is used then last 10 records will be loaded again.
If a record is created when load was running, those records may get lost. To prevent this situation, lower limit can be used to backup the starting sequence number.
This may result in some records being processed more than once; therefore, be sure this DataSources is only feeding an ODS Object.

Generic Datasource with Fuction Module with delta on Created Date

Hi Experts,
I have created a generic datasource using Function Module RSAX_BIW_GET_DATA. I have copied this function module and created a my own Function Module. I want to load delta using this. But I don't know how to handle delta in the code.
my code is working for full load but not for delta. I have seen that in ROOSOURCE tabel the Delta field is showing the AIE instead of D and extraction method is showing as F2. I have searched a lot of forums and articles but didn't get how to handle this.
Please advice.

Hi Amit,
Go through the link as suggested by AKhan which lets you understand the concept of offsets and the last extraction status.
In case of Table or View based GDS, the system takes care of the deltas based on the selections you make in the "Generic Delta" screen whereas in case of FM based DS, it is your responsibility to handle this part. Within your code, capture if the load is a Delta load (I_UPDMODE = D). Since your delta is on Created Date, maintain a Z table with name of the DS as the Key and a field representing the current value of the Delta field(created date in this case). When you first load the delta, there will be no record for your DS in this table. Create an entry with the current day. Next time when you load a delta, take this value, compare it with sy-datum and get all the records falling within these days. This has to be done in the Select stmt. Once selection happens, replace the value in the Z table with sy-datum. This way you can simulate the delta. The Z table can be used for other FM based Datasources also as it has DS as the key.
It would be easy if the exact SAP table where RSA7 delta field status is stored is known. Otherwise, the above method can be used.
Revert for any further queries.
