EXCEL Web Query - load into SAP via Web dynpro or standard ABAP

Hi everybody
I was wondering if you can run an EXCEL WEB Query from abap and then upload the data retrieved from the web into SAP using either a web dynpro application or standard SAP.
For standard ABAP one could probably run the EXCEL web query by executing some code such as
call method cl_gui_frontend_services=>execute
exporting
document = 'your excel web query file'.
You could then save the data and using GUI_UPLOAD get it into sap.
I'd really like to do it via a web dynpro application.
Any ideas anyone.
For guys who've never used EXCEL web queries --quite easy.
Open EXCEL
go to Import External Data
Choose New web query
Enter URL of where you want to retrieve your data from such as YAHOO finance etc.
For example to get the components of the Dow Jones Composite Index (^DJA) use this url
http://finance.yahoo.com/q/cp?s=%5EDJA
click the yellow arrow on the table data you want to import. The arrow will turn Green and press IMPORT
Then enter the cell number where you want to start importing data
Hey presto you've got your data from the web.
Cheers
jimbo

when you create a new webquery, in the properties, you can set when the page should refresh (data fetch to happen), you can set that to refresh at file open.
then you can use either OLE or gui_upload to upload the excel to read the data.
have couple of question:
why do you want to choose excel webquery ?=> is it because the ability to get unstructured data from the web?
what sort of data you are trying to read from the web?=> most of data centric sites (forex, stock quotes) will have either RSS feeds or some web APIs to get data which can be easily consumed by ABAP

How to build a WEBI query on a SAP NANA OLAP connection?

hi fellows,
we all know that a relational connection can be built to SAP HANA database, and we build data foundation, biz layer to publish it to the repository, so that we can create a WEBI report based on a query to visit the universe.
However, does anybody know how to create a WEBI query on a SAP HANA OLAP connection? Since we don't need to build any data foundation on it.
I created a sap hana olap connection, but failed to find anywhere to publish it? Can anybody help?
thanks,
Jennifer

Data load into SAP ECC from Non SAP system

Hi Experts,
I am very new to BODS and I have want to load historical data from non SAP source system into SAP R/3 tables like VBAK,VBAP using BODS, Can you please provide steps/documents or guidelines on how to achieve this.
Regards,
Monil

Hi
In order to load into SAP you have the following options
1. Use IDocs. There are several standard IDocs in ECC for specific objects (MATMAS for materials, DEBMAS for customers, etc., ) You can generate and send IDocs as messages to the SAP Target using BODS.
2. Use LSMW programs to load into SAP Target. These programs will require input files generated in specific layouts generated using BODS.
3. Direct Input - The direct input method is to write ABAP programs targetting on specific tables. This approach is very complex and hence a lot of thought process needs to be applied.
The OSS Notes supplied in previous messages are all excellent guidance to steer you in the right direction on the choice of load, etc.,
However, the data load into SAP needs to be object specific. So targetting merely the sales tables will not help as the sales document data held in VBAK and VBAP tables you mentioned are related to Articles. These tables will hold sales document data for already created articles. So if you want to specifically target these tables, then you may need to prepare an LSMW program for the purpose.
To answer your question on whether it is possible to load objects like Materials, customers, vendors etc using BODS, it is yes you can.
Below is a standard list of IDocs that you can use for this purpose to load into SAP ECC system from a non SAP system.
Customer Master - DEBMAS
Article Master - ARTMAS
Material Master - MATMAS
Vendor Master - CREMAS
Purchase Info Records (PIR) - INFREC
The list is endless.........
In order to achieve this, you will need to get the functional design consultants to provide ETL mapping for the legacy data to IDoc target schema and fields (better to ahve sa tech table names and fields too). You should then prepare the data after putting it through the standard check table validations for each object along with any business specific conversion rules and validations applied. Having prepared this data, you can either generate flat file output for load into SAP using LSMW programs or generate IDoc messages to the target SAPsystem.
If you are going to post IDocs directly into SAP target using BODS, you will need to create a partner profile for BODS to send IDocs and define the IDocs you need as inbound IDocs. There are few more setings like RFC connectivity, authorizations etc, in order for BODS to successfully send IDocs into the SAP Target.
Do let me know if you need more info on any specific queries or issues you may encounter.
kind regards

Authorization Check when logon into SAP via ITS

Hello
We have implemented Authorization Check after user have logged on to SAP via ITS in this User Exit SUSR0001. It was working fine in 46C version, but after upgrade to ERP 2005, when user logs on into SAP via ITS, this user exits is ignored, while logging normally via SAP GUI; authorization check is performed as before?
Did anyone else have experienced the same problem?

From what I understand something on that line changed. We are still hanging on to our external ITS 6.20 so I am afraid I can not go into details.

Decimals cut off loading into Essbase via DIM

Have you ever run into the issue of small numbers (9 decimals) getting cut off/rounded when loading into Essbase via DIM? When I try to load rates into my Essbase app via DIM they get cut off at 6 decimals even the though the entire rate is 9. For instance, the rate 0.752615338 coming out of the source gets stored in the target as 0.752615. Also, if a load a text file with the 9 digit rate into my target app via DIM it STILL gets cut off. Therefore, I've isolated the issue to the loading of data into the target. I cannot modify the precision, however, for my target. Any thoughts?

Ha ha! Oy! It's like having bees live in your head. You are correct Russ! iTunes 11.2.1. Thanks. I went to verify the release number and looked right at iTunes and my fingers typed Safari. Funny how that works. Back to work!

Webi query performance in SAP BO 4.0 sp6

Hello,
I'm facing an issue with the webi reports in our BI 4 SP6 environment. The webi reports data fetch time is ridiculously slow, where as when these queries are run on Oracle 10g the results are returned much faster as compared to WebI. The same reports used to fetch data faster few months ago when we were on SP4.
Now my question is what can I do to improve the query data fetch time in webi? Is there some parameter that I can tweak in BO or do I need to add more services? Please suggest. thanks
Following are the specs of the QA environment:
We are using a clustered environment with 2 nodes (CUSNWA3T and CUSNWA3U) - these are the names of the nodes. Each node has 12 GB of RAM and each node is a VMware virtual machine running on windows server 2008. Each of these BO servers/nodes is having its own CMS server, I have broken down the APS into sub servers after facing issues with the DSL Bridge service.
Regards,
samique

Andreas,
thats for reply. Yep I agree with your suggestion about the RAM is there any document that details out how much RAM and processing power is required by SAP BO 4.x?
I had to turn down the explorer, crystal reports, AJS, Dashboard Services just to provide for the APS. I did break down the APS as well according to a document that I found on SAP site.
Here is what worked for me: we use DW relational connections for the universes, all our universes are UNX universes. In the connection there are options for: Array bind size, Array Fetch size and pooling timeout. I increased all those, array bind size to 250; Array fetch size to 32670 and pooling timeout to 20 mins and the dba set the ConnectInit to set star schema transformation. Once all these were enabled the report which was loading in 20 mins started refreshing in 6 mins.
For now things seem to be working fine but I will certainly raise the RAM request to the management but it would help if you could provide with some reference document. Thanks

samique

Webi Query Splitting into 2 different queries

Hi Guys,
- We are migrating from 5.1.6 to Xi-R3 environment.
- We have 2 universes. Let me call them Unv-A and Unv-B.
- 230 reports point to Unv-A and 22 reports point to Unv-B.
Unv-B has most of the objects, tables, classes, contexts etc from Unv-A along with some additional or extra objects, tables, classes, joins and contexts.
We have analysed and merged the two universes Unv-A and Unv-B and named it as Unv-A since we have 230 reports pointing to Unv-A.
So far so good.
Now out of the 22 reports which were pointing to Unv-B, 10 reports are WEBI.
After pointing these 10 webi reports to the universe Unv-A, it is showing multiple queries in the SQL Editor.
some thing like
SQL Editor----
Synchronisation
Select 1
Select 2
and each "Select" displays its own query
even though the 5.1.6 webi reports has a single query.
Most of these webi reports are referring to a set of aggregate objects which have the format like
@Aggregate_Aware(
              sum(Schema1.table A.Column A),
              sum(Schema1.table B.Column B),
              sum(Schema1.table C.Column C),
              sum(Schema1.tableD.ColumnD)
The report just picks up the first condition "Schema1.table A.Column A" irrespective of the context we specify and creates a synchronized query.
The first condition is picked even though the table is not present in the context, and a Synchronized query is created.
I removed the first condition in the function and checked. It is displaying the desired query and result.
Would like to know if this is the only method, is it an issue with Aggregate_Aware function or something I am missing.
Appreciate your help and response,
Hoping for a quick response and a solution.
Thank You,
Arun

hi arun
Did you checked for the contexts in the universe accordingly the way you joined the tables.
if not, name separate context for each groups of joins.

Create external LDAP authentification to SAP via Web Dynpro

Hi Guys,
I have a requirement where I have to create access to SAP via external LDAP authentification. It is similiar how the Enterprise Portal works, but I want to achieve it with out the portal.
The user will enter his LDAP user and password and I will check via LDAP connector to grant access to SAP.
The only Problem I have is to switch to SAP user without knowing the SAP Password. Thats why I need external authentification.
I have been told by an basis expert that I could use java to achieve this. I have also got the java coding what the Enterprise Portal uses.
Am I on the right way? Can anybody advice me.
Thanks and best regards

Mass data load into SAP R/3 - with XI?

Hi guys!
I have an issue - mass data migration into SAP R/3. Is XI a good solution? It will be about 60GB of data. Or is there a better way of this data load?
Thanx a lot!
Olian

hi,
SAP doesn't recomment using XI for mass data migration
and 60 Gb is certainly too much
use LSMW for that purpose

Loading scripts - what's the difference between loading into edge via script window and including a script in the html document?

I have a html page that loading in two edge compositions and an external custom javascript file. The javacsript file includes the bootstrapCallback so I can store references to the loaded compositions and can communicate with them. This seems to work well. The problem have is when I also try and load in a custom plugin javascript files into the edge compositions via the script window inside edge - I don't understand how this works, for example if I load in a custom javascript file into one of the compositions can only that composition use it's funcitionality? Is loading in scripts via edge script window the same as including in html document, I'm confused how the two relate, please help me understand.

How do I get music loaded into itunes via CD synced into ipad?

sync seems to only want to load music onto the ipad that was purchased within itunes. I have a lot of old CDs have loaded into itunes on my macbook pro that have been synced to my ipod, why won't they also sync to the ipad?

after another trip to the Apple store (just glad there's one close) found out you must configure sync settings for each device attached to your iTunes library. So made the ipad the current device, clicked on Music (on the horizontal menu bar that begins with Summary), selected the desired sync options, synced and now have all my albums on the ipad. only they aren't showing as albums but each individual "song" (even for a symphony)

XML/Web Service Load into Delta queue

Hello,
What is the mechanism to push an XML file into the BW delta queue for use by an XML/SOAP or Web service based datasource? There is no XI in the picture so the XI based how/to papers are not germane to this question. The HOWTO paper on XML load has a script for loading an XML file but it errors out on creation of the Activex object, plus it needs XML parser etc. Is there an SAP approved way of routinely loading XML files into the delta queue versus some test script?

This can be done in BW.
Try the links given below, also there is a How to document available from SAP on this.
