Clarification on Datasource -A.H.P, VISHVESH,ABY PLZ

Hi gurus,
i have few fields out of which maximum i found a standard datasources form production planning
but few are left from tables like mara, marc, eket
and i found few datasources which are extracting from these tables like purchasing and inventory management Ds but they don't have the fields i want from those tables,
my doubt is can i enhance these datasource with that field i want from these tables (MARC, MARA) EKET, EKPO
but what i am thinking is like
1.WILL IT BE OKAY IF I AM POPULATING FEW FIELDS FROM ONE DATASOURCE AND ONLY ONE FIELD FROM DIFFERENT DATASOURCE that too from different application altogether.
WILL THE INFORMATION BE CORRECT LIKE WILL IT BE RELATED WITH THE DATA ALREADY EXTRACTED FROM THE STANDARD DATASOURCES OF different application (PP).
BECOZ THE TABLES AND FIELDS REQUIRED BY CLIENT IS MATCHING BUT I AM WORRIED WILL THIS MAKE SENSE when we report on it .
THANKS AND REGARDS
HARISH

Hi all,
Arun, can u kindly explain me the below
<i>If the structures match , use different data sources into the same ODS layer in BW</i>
like what do u mean structure can u kindly explain with an example here my requirement is that i have key figures and characters which are coming from two different application areas as PP and MM but most of them i found in standard datasources of PP and few like say 5 i could only find in MM tables MARA and MARC and EKET, EKPO.
i am confused how these single fields will be matched with those PP fields and give readable definition.
becoz if i am getting quantity from MARA r Date from these tables how can i corelate with the already extracted data of PP becoz date & Quantity will be related to their fields how can i do this...
ABY...
can u kindly explain me how this is possible of creating a view with using foriegn key like as i mentioned earlier if Mara is having a DAte and Quantity coming from different table how should i relate do i need to add few more fields just to make this info sensible
thanks and regards
harish

In RS02 why DataSource for Hierachy is not there.. plz help

hi bw experts,
can u plz tell me in RS02 tcode why datasource for hierarchy is not there.
plz explain me in brief..
thanks & regards
vijay...

Hi,
In RS02 we won't have Hierarchy DataSource bocoz the OLTP system is based on the ERM (Entity Relationship Model) where we will have only ONE to ONE relation i.e., two dimensional table design. Which basically won't support the ONE to MANY Relation. If we want to connect the tables means we will connect by means on the PRIMARY KEY and FOREIGN KEY relations. which won't support Hierachy DataSource.
I think it will help u a little bit.

Error while triggering Infopackage

Hi experts,
I am encountering an error when i am scheduling the infopackage.
I m using an Infosource which is connected by two Data sources (Excel).
when i trigger Infopackage1 for DS1 it is excuting correctly.
But When I excute the second Infopackage with Second DS then it is giving an error msg "Fiscal year variant UN is not maintained for calendar year 0710 ".
But in both above DataSources same UN has been used.
plz give me ur valueble suggetions.
thanks in advance

Hi Bhaskar,
Just in case check the record in the excel and check the date format / year for that record . Modify the record and then should be able to load it successfully .
Hope that helps.

Creating VLAN

How is VLANs configured on a switch ? What are the parameters defined while creating a VLAN/ Voice VLAN ? Since switch operates on layer 2 switch, is it required to define vlans on router as well. This might be very simple and basics of networking. Need to understand to clarify my doubts.
Thanks
Feroz
Sent from Cisco Technical Support iPhone App

HI Feroz,
VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLAN’s, a switch can create the broadcast domain.
This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain.
Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
Please find the details below:
Vlan on Switches:-
Two types of Vlan(Layer 2 - Layer3)
Layer 2 vlan:
config t# vlan
Eg:
Let’s say we wanted to create VLAN’s 5 and 10. We want to put ports 2 in VLAN 5 (Marketing) and port 3 in VLAN 10 (Human Resources). On a Cisco 2950 switch, here is how you would do it:
# vlan 5
#name marketing
vlan 10
name humanresouces
exit
int f0/2
switchport mode access
switchport access vlan 5
int f0/3
switchport mode access
switchport access vlan 10
Layer 3:
conf t# interface vlan 2
followed by ip address.
Please find below link which explains complete info on VLans.
http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_9_ea1/configuration/guide/swvlan.html
2- Vlan on Router:
A vlan configuration on a router is slightly different than on a switch. On a switch, you would create the vlan and then the routed vlan interface.
On a router you tie a vlan to a subinterface. You need to create the subinterface and then do the encapsulation dot1q command. This command basically assigned the vlan to the subinterface. In this example, there are 2 vlans, vlan 100 and 201. On the eth 0/0 interface, I created two subinterfaces. fastethernet0/0.100 and f0/0.201. Notice that I matched the subinterface number with the vlan ID. You do not have to do this, but it is a best practice and really helps you as the administrator keep things organized. So, under f0/0.100, there is the encapsulation dot1q 100, which basically binds vlan 100 to subinterface f0/0.100, then I assigned the IP. The same is for the other subinterface. So the router is trunking two vlans on its f0/0 interface, vlan's 100 and 201.
interface FastEthernet0/0

Clarification on some reading: Datasource and Function Module extraction

Hi,
I found a link on Help.sap which explains how to create a function module and I have some questions after my review:
It basically uses function module to read some filght data from the table SPFLI
1.
I got into this research since one of the methods for data extraction from R3/ECC to BW is through Function Modules.
Why couldn't that extraction be based on a view of the table SPFLI.
i.e. why is this complication of writing an ABAP code to achieve something which could be done with a DB view or table?
2.
Any example or scenario where you think a datasource could NOT be created based on a table, Database View or Sap Query and that it must be done with a Function Module?
3.
So, once the function module is successfully created; how to do create a Datasource based on this function modeule to take care of the delta's on the source data?
4.
There was a discussion about "remote function call" which I did not get completely. Will extracting data from R3/ECC to BI be regarded as "remote call"
Thanks

1. Why couldn't that extraction be based on a view of the table SPFLI. i.e. why is this complication of writing an ABAP code to achieve something which could be done with a DB view or table?
A DataSource could have been created directly from table SPFLI. It was used as an example in the case of the document is my guess. There are some table types, however, that you cannot create a DataSource directly off of.
2. Any example or scenario where you think a datasource could NOT be created based on a table, Database View or Sap Query and that it must be done with a Function Module?
Pool/Cluster tables cannot be directly read and therefore must use a Function Module for extraction. Another reason for using a Function Module, even against a single table, is in the case that you have more than one field that you want to create a generic delta against. SAP delivers the capability in the application to set a generic delta on only one field within the DataSource. If there is more than one, say created on and changed on dates, a Function Module is require in order to enable that.
3. So, once the function module is successfully created; how to do create a Datasource based on this function modeule to take care of the delta's on the source data?
Go to tocde RSO2, enter the DataSource name, click on the Create button. In the next screen, there are three buttons toward the top to tell what is the source of the DataSource: 1) Extraction from View (default); 2) Extraction from Query; and 3) Extraction from Function Module. When you click on the Extraction from Function Module button, the View/Table field will gray out and the Function Module and Extraction Structure fields will un-gray.
4. There was a discussion about "remote function call" which I did not get completely. Will extracting data from R3/ECC to BI be regarded as "remote call"
I think that this is referring to a process whereby you create a remote-enabled Function Module on the source R3/ECC system and then create an ABAP program in BW that calls that remote-enabled Function Module. Basically, the ABAP program on BW would send some parameters through to the remote-enabled Function Module on R3/ECC. The Function Module would extract data into an internal table and then pass that internal table back through to the ABAP program in BW for further processing.

Enhancing standard datasource, small clarification.

I have gone thru Robert's blog it says
*"One method of adding user-defined fields is the following: add the required fields to the communication structures (MCVBAK, MCVBAP and so on ) using the append method (via SE11) and then use the LIS customer exits to fill the field.
For information on enhancing the communication structures, you can see the documentation for the enhancements MCS10001, MCS50001 and MCS60001 provided in transaction SMOD.
After you enhance the communication structures you can then enhance the extract structure with the relevant field in the customizing cockpit (transaction LBWE), provided that the communication structure is available in the selection. Then you can proceed with the steps described before in the previous bullet."*
See if in one DS 2LIS_11_VASCL he want to add a field AUDAT and my doubt is how can he add that field to the communication structure so that he can select it from that DS communication structure to the left side, Is it possible can we add what ever fields to the communication structure. I thought we should append the datasource and then enhance the respective function exit rite. Why are we talking about append method via SE11, can anyone please guide what do we mean by appending it throug se11 to the communication structure. What i know is if we do not find the required filed in any standard ds we can append the ds and edit the related include program or use 2 DS's to get the required fields to a single cube on BI side after activating those fields if we know those field names. What is the concept of adding fields to the communication strucute using append method via SE11. Please guide me in detail. Thanks in advance.

HI,
I havent seen the blog but initially I guess you are confusing extract structure in R/3 with the communication structure in BW.
MCVBAK and MCVBAP etc. are not exactly extract structure for the data source its a communication structure for the tables which will be used to extract data from the VBAK and VBAP and can be used by anyone.
A data source can be based on more then one tables and therefore may use more then one structure based on this table.This can combine MCVBAK and MCVBAP and many more structure together.
This is the extract structure you see in LBWE for a particular data source.
I think to differentiate between these two type structure he would have used the term communication structure and through these structure the extract queue communicates with the tables.
I guess In 3.5 the point was of giving the look of BW flow same as r/3 for better understanding.
So one communication structure can be updated by many transfer rules in BW..similary one extract structure can be updated with many rules or structure below it in R/3.
Dont confuse it with the communication structure in the BW.
You cannot do any thing related to communication structure in BW in CMOD.
Thanks

Multiple DataTargets in a BI 7.0 System to One DataSource in Source System

Currently, I do not have access to BI 7.0 system. I am wondering whether it is possible to connect MULTIPLE DataTargets of a single BI 7.0 system to ONE DataSource in the source system? I have searched the forum, but I couldn't find relevant posts. If I am not wrong, until BW 3.5, once a DataSource is assigned to an InfoSource, it can not be assigned to any other InfoSource of the same BW system. I have heard that this has changed in BI 7.0 with the new DataFlow concept.
The current requirement is that multiple DataTargets of a single BI system need to get DELTA data from the same DataSource in the source system. If this is technically possible in BI 7.0, should the source system also support such an assignment (since the DELTA load timestamps are maintained in the source system)? What source systems currently support this feature, if any? What are the appropriate tables in the source system that I need to look at to do further investigation?
All the useful inputs regarding these questions will be rewarded with points. Let me know if you need any further clarification of the requirement. Thanks!
Sameer

Hi Sameer,
But since there is only one transformation between the PSA and DataTarget, all the data (irrespective of the indicator) will flow through unless I filter on the "planning stage" indicator
You can create one transformation between Datasource and ONE DataTarget. But in your case, you have TWO datatargets. So you have to create two DTP's which can have diffrent filter parameters.
You can fill two different targets ( cube1: before manual update, cube2: after manual update) using your datasource.
For this, you need to create two transformation. Keep in mind, everytime you create a transformation you must create a DTP for data movement.
So you will have:
DS1 -- TRANS1-- DTP1 --Cube1
DS1 -- TRANS2DTP2Cube 2
In DTP1 set filter for indicator :X and DTP2 set filter for indicator :Y. Both DTP1 and DTP2 should work in delta mode.
I would suggest you to create one initialization for your DS1. if it is not possible create two infopackages for two initializations. I suppose you have the indicator in selection parameters of infopackages.

Select option greyed out for fields of custom DataSource (rso2, rsa6)

Hi
Why are several fields, in my custom DataSource (created in rso2) not available for select?
I do not think this is a permission issue, since several fields are selectable, but not all fields.
It is not the data type, since I see other custom DataSources that have the same data type, and it is selectable as a select option.
This is not a DataSource that was provided by SAP, it is completely custom, and uses a custom data definition (defined as a structure via se11), and a custom function.
I have read the responses to similar questions, but have not found an answer that explains how to make the field selectable for select.
What determines which fields can be selected for selection, and which fields have this option greyed out (not selectable)?
I have come across multiple answers, for similar questions, that suggest an abap program to directly update table roosfield.
Is this safe?
IF I choose this route will I need to run the update program on production, or will the change it makes to my dataSource transport with my transport?
(I can test this).
What I most need to know is If this suggestion is safe, or if it has side effects?
Thank you

Hi Eileen,
In Least case to enable the selection for the fields with the below program:
Below code is for your reference which will use to unhide objects in RSO2 or RSA6 for Data source( in code for BELNR, KUNNR, VBELN, BUDAT fields are unhiding for 0fi_ar_4 data source selection option) . Still need any clarifications let me know.
SE38: Create a program for ref below code.
REPORT ZNP_SELE_DS.
tables: ROOSFIELD.
UPDATE ROOSFIELD SET SELECTION = 'P'
WHERE OLTPSOURCE = '0FI_AR_4' AND OBJVERS = 'A' AND FIELD = 'BELNR'.
UPDATE ROOSFIELD SET SELECTION = 'P'
WHERE OLTPSOURCE = '0FI_AR_4' AND OBJVERS = 'A' AND FIELD = 'KUNNR'.
UPDATE ROOSFIELD SET SELECTION = 'P'
WHERE OLTPSOURCE = '0FI_AR_4' AND OBJVERS = 'A' AND FIELD = 'VBELN'.
UPDATE ROOSFIELD SET SELECTION = 'P'
WHERE OLTPSOURCE = '0FI_AR_4' AND OBJVERS = 'A' AND FIELD = 'BUDAT'.

Reviewed documentation on Reporting: I will appreciate some clarification

Hi,
Reviewed documentation on Reporting: I will appreciate some clarification:
1. Can you help me understand what "Staging" means as used here:
A data warehouse system serves primarily to stage information from various data source
The information is staged in various forms including personalized reports, freely definable queries, and predefined reports.
2. Is RemoteCube the same as Virtual Cubes? if not, what is the difference?
3. Can you help me understand what "flexible update" means as used here:
Characteristic InfoObjects have to be included in the InfoProvider tree in the Data Warehousing Workbench to make them available as data targets for flexible updates and as InfoProviders for reporting.
4. "DataStore Objects are available for transaction data and for master data."
When do we decide to store master data in a DSO?
5. Formula Collision vs. "Exception Aggregation"
I understand what formula collision is about but is it the same as "Exception Aggregation"?
If not, do you have a real-life example to help me understand the concept of "Exception Aggregation"?
The documentation/link is not helping.
6. i. With the followin limitation on Display attribute, why not always make the attribute Navigational?
"You can show Display Attributes in a report in the drilldown. However, navigation steps are not possible. (For example, you cannot choose values from a display attribute as a filter.)"
ii. Any example where Nav Attrib does not make sense but it must be Display attrib?
Thanks

Hi Amanda,
2. Is RemoteCube the same as Virtual Cubes? if not, what is the difference?
Yes, they are one and the same.
3.Can you help me understand what "flexible update" means as used here:
Characteristic InfoObjects have to be included in the InfoProvider tree in the Data Warehousing Workbench to make them available as data targets for flexible updates and as InfoProviders for reporting.
in 3.x, you have infosources and not transformations. So you have basically two types of infosources, direct update and flexible update.
Direct update infosources do not have any update rules. These are used for master data loading since the format of data is usually fixed as in fields etc.
Flexible update datasources have update rules, which means that you can use it for loading pretty much anything. You can load master data by changing the update rules and you can use the same infosource for loading transactional data as well. What the statement means is that the infoobject has been set as an infoprovider. and therefore it can be used as a source in a query. The loading is done via flexible updates.
More info on direct and flexible updates can be found here :[3.x InfoSource Types|http://help.sap.com/erp2005_ehp_04/helpdata/EN/87/3fdf9587f211d5b2ff0050da4c74dc/frameset.htm]

I understand what formula collision is about but is it the same as "Exception Aggregation"?
If not, do you have a real-life example to help me understand the concept of "Exception Aggregation"?
The documentation/link is not helping.
I'm glad that you understand what formula collision is...since its a difficult concept. Exception aggregation is much simpler.
For every key figure that is present in BW, there are two types of aggregations that can be maintained.
Standard: can be sum etc.
and exception aggregation like avg etc. When you do this, you need to give a reference characteristic. By default this is time. and usually it is summation. Now when you drilldown in your query based on the ref. characteristic, the exception aggregation is used.
Eg [http://help.sap.com/saphelp_nw70/helpdata/en/d2/e0173f5ff48443e10000000a114084/frameset.htm]
6. With the followin limitation on Display attribute, why not always make the attribute Navigational?
"You can show Display Attributes in a report in the drilldown. However, navigation steps are not possible. (For example, you cannot choose values from a display attribute as a filter.)"
ii. Any example where Nav Attrib does not make sense but it must be Display attrib?
Essentially this is a preference or a personal choice basically. You can have several attributes. but keeping all of them as navigational does not help and degrades system performance as they have to be interlinked. For eg.
You have an employee ID as your characteristic.
attributes are as follows
Date of birth
division
salary stack
*** etc
now things like division,salary stack and *** could be used as filters in a query but date of birth would in general not be used as filter and hence would make no sense to use it as a navigational attribute(unless you want to find all employees whose birthday is a certain date ).
In the end, it just comes down to the requirement. If you are required to put a filter on an attribute of master data, then it needs to be a nav. attribute else a display attribute would suffice.
Hope this helps.
Regards.

Blog Clarification: Role of BI developer to get Deltas functional (part 1)

Hi,
I will appreciate some clarification on the following blog that I reviewed:
/people/swapna.gollakota/blog/2007/12/27/how-does-a-datasource-communicates-delta-with-bw
This blog seems to be suggesting that as a BI developer, you need to know the DELTA TYPEs for each datasource (selected in R3) and with that knowledge, you will be in a better position to choose Update types in ODS/DSO Overwrite or Addition, in the BW/BI environment.
At least that is what I came up with from the review.
1. For each datasource you activate as a BW developer in the BW environment, do you really need to go to R3 and study this datasource through the table RODELTAM to see the datasource type e.g. ABR, ABR1, etc and all the settings such as serialization =1 or 2?
2. I thought these datasouces, e.g. 2LIS_02_HDR are SAP delivered, ready to be used, isnu2019t it?
So, I understood that a decision will have to be made between ABR and ABR1 as the delta type.
i. whose responsibility is it to make such decisions?
ii. The R3 folks or the BW developer?
iii. What influences such decision making?
iv. In this table(RODELTAM), on R3, I saw several u201CXu201Ds under different columns, who sets these?
3. There were also discussions as to whether a datasource supports DSO/Cube or not?
Does this support the argument to study a datasource on R3 side in the table RODELTAM before using it?
Thanks

If you are a newbie and using it for the first time ofcourse you have to.But I would simply use RSA2 transaction than those tables.

Ofcourse its BW developer who deals with BW related things.

Your datamodel.
3. There were also discussions as to whether a datasource supports DSO/Cube or not?
Does this support the argument to study a datasource on R3 side in the table RODELTAM before using it?
Datasource supports DSO/Cube, thats the whole point for determining the type of delta.
Hope this helps.

Weblogic - Fusion Middleware Cluster - Clarification - 11g

Hello All,
I've checked the forum and would need just a little clarification regarding weblogic cluster & fusion Middleware + Load Balancing.
My current Setup is:
==============
1 APP Server: Runs Fusion Middleware 11g Forms and Reports + Weblogic + OHS (windows 2008R2)
1 DB Server: Standalone database 11gR2 installation (windows 2008R2)
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
What do I do? Do I install the new app server like the first one and just add it to an existing domain(clustering)? Is there a difference between fusion middleware clustering and weblogic clustering (as in database RAC - the whole idea being failover 24/7 no single point of failure?)
I would appreciate any assistance, and need not great detail, just need to make sense of the whole thing.
I'm already on with the following document: [http://docs.oracle.com/cd/E21764_01/web.1111/e13709/toc.htm]
Thanks in advance
Jan S.

Hi Jan
You are almost there. I would like to clarify some points for you.
1. You already have WLS + Forms/Reports and of course Backend RCU Database that has all the meta data for Forms/Reports. This RCU database is on single server Oracle database.
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
2. The first question for above requirement is, do you need the new Server on the same Existing physical box or a different remote physical box. If on the same physical box (which I doubt), then there is NO need to install any new software like WLS, Forms/Reports etc. All you do is create a new Managed Server and add it to your existing Domain. NOW, do you currently have a Clustered Domain. If you, all you do is add this new server to that cluster. If not, then you need to add a New cluster and add your old and this NEW managed server to that Cluster. If your existing domain is only single server and is very recent, I would prefer create a brand new Cluster domain with Different Port numbers (you can change port numbers anytime later also). Then add/create one or two managed servers.
3. If you are give a new physical box for this new managed server, then YES, you do need to install exactly SAME version of Weblogic Server and same version of Forms/Reports server on this new machine. Then create a Cluster Domain with 2 managed servers. One managed server on first box where you will have Admin Server + Managed Server 1. Then run pack command. Go to other machine. Run unpack command to create second Managed Server. Now you got 2 managed servers in a Single Clustered Domain.
4. Now comes the Load Balancing Part. Never ever expose the individual managed server host and port and WebApp urls for any Clustered Domain. Instead install Apache Http Web App Server which I guess is same as Oracle Http Server. Oracle renamed it (there is no need for this, but it may be company policy). Anyhow all you do is, just install Apache Web Server. Copy some .dll (.so on linux) files to this apache installation. Then update httpd.conf file or weblogic.conf file with details of clustered weblogic domain managed servers host, port, url patterns etc.
5. All the External Requests will now go to Apache Web Server like http://apachehost:apacheport/xxxUrl. This Apache will take care of LOAD Balancing, Failover etc and based on input url pattern will redirect requests to back end cluster of weblogic managed servers.
6. The backend RCU database that has Metadata for Forms/Reports NEED NOT be Clustered. If you really have extremely heavy data, then you can have Oracle RAC database. Have multiple DB Nodes in RAC. For each Node, create a DataSource in Weblogic conolse and finally one master Multi Data Soiurce that uses all these single Datasources. But very rarely you really need RAC or clustered database for RCU. So for now, just go with single non-clustered Database that has RCU Schemas.
In conclusion, even though you have Forms/Reports, just follow the standard normal Weblogic Clustered domain Architecture for your requirement. All clustering is at application server level and nothing to do with any Oracles softwares like SOA/BPM, Forms/Report, BI etc etc.
Thanks

1 DataSource for 2 DSO
