Best Practices for Cube Mapping

I have been experiencing some challenges in mapping and loading my cube with dimension foreign keys. Does anyone know of a best way for mapping dimension surogate keys to the cube? Do I have to map each dimension separately since I have some dimension tables if joined would create tremendous Cartesian Product. OWB documentation does not contain a clear example of mapping dimension keys to the cube. Your help would be greatly appreciated.

Good morning,
There are basically 2 ways of doing it.
1)
As Remco mentioned, simply use lookup-operators on all dimensions for which you have values in your source, drag the ID's of these dimensions and all measures from your source into your target cube.
This solution will outer-join on all dimensions, enabling you to define some dummy value in case there's no reference for any specific dimension value in your source.
2)
Join your source with all dimensions for which you have values in your source, drag the ID's of these dimensions and all measures from your source into your target cube.
Here you have full control over the join statement, i.e. full liberty in choosing whether dimension references are mandatory (thus no dummy-values allowed) or not (hence using outer join for that specific dimension).
Hope this helps.
Good luck, Patrick

Best Practice For Cube Design

All,
First post here and was wondering if anyone out there has a best practice for cube design or optimisation. Currently have 7 Cubes that have been populated for the last 6 months and am now looking at ways of speeding up their population.
Are there any hard and fast rules about dimensions?
Should they be kept to a percentage of the fact table?
When should line item dimensions be used?
Regards
Gary Boyle

Hi Gary,
Ideally the DIM tables should be 20% of the fact table and preferably less. You can check the size ratios in RSRV using the Database tables test > Database info about InfoProvider tables. Line items dimensions should be employed where the char has a large number of unique values (like 0MATERIAL, or 0CUSTOMER), so that anothe DIM ID is not created, but the SID values are used directly in the Fact Table.

Best practices for loading apo planning book data to cube for reporting

Hi,
I would like to know whether there are any Best practices for loading apo planning book data to cube for reporting.
I have seen 2 types of Design:
1) The Planning Book Extractor data is Loaded first to the APO BW system within a Cube, and then get transferred to the Actual BW system. Reports are run from the Actual BW system cube.
2) The Planning Book Extractor data is loaded directly to a cube within the Actual BW system.
We do these data loads during evening hours once in a day.
Rgds
Gk

Hi GK,
What I have normally seen is:
1) Data would be extracted from APO Planning Area to APO Cube (FOR BACKUP purpose). Weekly or monthly, depending on how much data change you expect, or how critical it is for business. Backups are mostly monthly for DP.
2) Data extracted from APO planning area directly to DSO of staging layer in BW, and then to BW cubes, for reporting.
For DP monthly, SNP daily
You can also use the option 1 that you mentioned below. In this case, the APO cube is the backup cube, while the BW cube is the one that you could use for reporting, and this BW cube gets data from APO cube.
Benefit in this case is that we have to extract data from Planning Area only once. So, planning area is available for jobs/users for more time. However, backup and reporting extraction are getting mixed in this case, so issues in the flow could impact both the backup and the reporting. We have used this scenario recently, and yet to see the full impact.

Best practices for ARM - please help!!!

Hi all,
Can you please help with any pointers / links to documents describing best practices for "who should be creating" the GRC request in below workflow of ARM in GRC 10.0??
Create GRC request -> role approver -> risk manager -> security team
options are : end user / Manager / Functional super users / security team.
End user and manager not possible- we can not train so many people. Functional team is refusing since its a lot of work. Please help me with pointers to any best practices documents.
Thanks!!!!

In this case, I recommend proposing that the department managers create GRC Access Requests. In order for the managers to comprehend the new process, you should create a separate "Role Catalog" that describes what abilities each role enables. This Role Catalog needs to be taught to the department Managers, and they need to fully understand what tcodes and abilities are inside of each role. From your workflow design, it looks like Role Owners should be brought into these workshops.
You might consider a Role Catalog that the manager could filter on and make selections from. For example, an AP manager could select "Accounts Payable" roles, and then choose from a smaller list of AP-related roles. You could map business functions or tasks to specific technical roles. The design flaw here, of course, is the way your technical roles have been designed.
The point being, GRC AC 10 is not business-user friendly, so using an intuitive "Role Catalog" really helps the managers understand which technical roles they should be selecting in GRC ARs. They can use this catalog to spit out a list of technical role names that they can then search for within the GRC Access Request.
At all costs, avoid having end-users create ARs. They usually select the wrong access, and the process then becomes very long and drawn out because the role owners or security stages need to mix and match the access after the fact. You should choose a Requestor who has the highest chance of requesting the correct access. This is usually the user's Manager, but you need to propose this solution in a way that won't scare off the manager - at the end of the day, they do NOT want to take on more work.
If you are using SAP HR, then you can attempt HR Triggers for New User Access Requests, which automatically fill out and submit the GRC AR upon a specific HR action (New Hire, or Termination). I do not recommend going down this path, however. It is very confusing, time consuming, and difficult to integrate properly.
Good luck!

Basic Strategy / Best Practices for System Monitoring with Solution Manager

I am very new to SAP and the Basis group at my company. I will be working on a project to identify the best practices of System and Service level monitoring using Solution Manager. I have read a good amount about SAP Solution Manager and the concept of monitoring but need to begin mapping out a monitoring strategy.
We currently utilize the RZ20 transaction and basic CCMS monitors such as watching for update errors, availability, short dumps, etc.. What else should be monitored in order to proactively find possible issues. Are there any best practices you all have found when implimenting Monitoring for new solutions added to the SAP landscape.... what are common things we would want to monitor over say ERP, CRM, SRM, etc?
Thanks in advance for any comments or suggestions!

Hi Mike,
Did you try the following link ?
If not, it may be useful to some extent:
http://service.sap.com/bestpractices
---> Cross-Industry Packages ---> Best Practices for Solution Management
You have quite a few documents there - those on BPM may also cover Solution Monitoring aspects.
Best regards,

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

Best practice for how to access a set of wsdl and xsd files

I've recently beeing poking around with the Oracle ESB, which requires a bunch of wsdl and xsd files from HOME/bpel/system/xmllib. What is the best practice for including these files in a BPEL project? It seems like a bad idea to copy all these files into every project that uses the ESB, especially if there are quite a few consumers of the bus. Is there a way I can reference this directory from the project so that the files can just stay in a common place for all the projects that use them?
Bret

Hi,
I created a project (JDeveloper) with local xsd-files and tried to delete and recreate them in the structure pane with references to a version on the application server. After reopening the project I deployed it successfully to the bpel server. The process is working fine, but in the structure pane there is no information about any of the xsds anymore and the payload in the variables there is an exception (problem building schema).
How does bpel know where to look for the xsd-files and how does the mapping still work?
This cannot be the way to do it correctly. Do I have a chance to rework an existing project or do I have to rebuild it from scratch in order to have all the references right?
Thanks for any clue.

Best Practice for Multiple iTunes and One Account?

My wife and I share our account for our iPhone Applications and Songs in iTunes.
Can someone point me to a topic that covers a best practice for multiple iTunes syncing?
I travel a lot and keep my iPhone synced to my Macbook Pro while she uses the workstation at home to sync to. We keep the addresses and contacts and calendars synced through MobileMe, however, I'm trying to find the best way of pushing applications and songs I've bought over to the other PC so they're still around while I'm traveling for her to sync with.
Thoughts?

Hi Steve,
Might be trying for solution for a long time, If i understood your question clear let me clarify you few points.
You are trying to access the bex query which is designed with the exit's in the background based on the logic and trying to call the entire dimensions and key-figures in a single connection. Then you are trying to map those data in the charts.
Steve, try to make more connections based upon the logic and split them. use the same query but split them by sales per customer group, sales per day, sales per week by making three different connections and try. You can merge the prompts from all connections.
Hope this Helps!!!
Sorry if i misunderstood your question.

Best practice for calc measures

Hi,
I read in one of the olap blog from experts which says that best practice for creating the calc measures is to have them in a seperate cube.
My question is that suppose I have two cubes in a AW of different dimensionality. Both the cubes has some calc measures to be created.
So can I create one more cube(dedicated to calc measures) considering all the available dimensions in the AW and create the calc measures for both the cube which has different dimensionality?
If I cannot do this then this means that if I have two cubes having different dimensionality then I would need two more cubes to create the calc measures for them? if yes then what would be the size implecation of the AW?
Thanks in advance.
Thanks
Brijesh

"Can I create one more cube(dedicated to calc measures) considering all the available dimensions in the AW and create the calc measures for both the cube which has different dimensionality?"
Yes, you can.
This is a pretty common thing to do. Store your base measures efficiently and then use calculated measures with the 'superset' dimensionality to bring different shaped measures together for the purposes of calculations or simply to get them all in one 'hypercube' to simplify access by SQL query tools and apps.

Best practice for real time requierement

All,
I am trying to find out what is the best practice for reporting against real time data ?
is it while using
1 - webi against universe/bex query on the top of hybrid cubes ?
2 - Crystal report directly against the ECC data ?
3 - using another solution such as Data Fedrator ? or something different ?
I am looking to know if anyone got such req and also to share their experience
did they get some huge challenge against hybrid cubes ?
Thanks in advance for your help
Philippe

Well their first requierement was to get real time data .. if i am in Xcelsius and click refresh then i want it to load my last data ..
with live office , i can either schedule a crystal report and get the data delayed or use the option from live office to make iterfresh as right now .. is that a correct assumption ?
I was talking about BW, just in case they are willing to change the requierement to go from Real time to every 5 min
Just you know we are also thinking of the following option:
1 - modify the virtual provider on the CRM machine to get all the custom fields needed for the Xcelsius Dashboard
2 - Build some interactive report on the top of these Virtual Provider within CRM
3 - get the link to this report , it is one of the Report feature within CRM
4 - design and build your dashboard on the top of it
5 - EXport your swf file to the cRM web ui
we are trying to see which one is the best one

Best practice for dealing with Recordsets

Hi all,
I'm wondering what is best practice for dealing with data retrieved via JDBC as Recordsets without involving third part products such as Hibernate etc. I've been told to NOT use RecordSets throughout in my applications since they are taking up resources and are expensive. I'm wondering which collection type is best to convert RecordSets into. The apps I'm building are webbased using JSPs as presentation layer, beans and servlets.
Many thanks
Erik

There is no requirement that DAO's have a direct mapping to Database Tables. One of the advantages of the DAO pattern is that the business layer isn't directly aware of the persistence layer. If the joined data is used in the business code as if it were an unnormalized table, then you might want to provide a DAO for the joined data. If the joined data provides a subsiduray object within some particular object, you might add the access method to the DAO for the outer object.
eg:
In a user permissioning system where:
1 user has many userRoles
1 role has many userRoles
1 role has many rolePermissions
1 permission has many rolePermissions
ie. there is a many to many relationship between users and roles, and between roles and permissions.
The administrator needs to be able to add and delete permissions for roles and roles for users, so the crud for the rolePermissions table is probably most useful in the RoleDAO, and the crud for the userRoles table in the UserDAO. DOA's also can call each other.
During operation the system needs to be able to get all permissions for a user at login, so the UserDAO should provide a readPermissions method that does a rather complex join across the user, userRole, rolePermission and permission tables..
Note that f the system I just described were done with LDAP, a Hierarchical database or an Object database, the userRoles and rolePermissions tables wouldn't even exist, these are RDBMS artifacts since relational databases don't understand many to many relationships. This is good reason to avoid providing DAO's that give access to those tables.

Best practice for Global Address?

Good Morning,
I am new to Cisco firewalls and would like to know what is the best practice for creating an external ip address and port into my network and then redirecting that to a specific machine. I am thinking of using a global ip address and then only allowing this type of traffic to talk to the specific destnation and on that specific port. Is this the correct course of action? Or os there a better or more effecient way of allowing this process using ADSM.
Troy
Message was edited by: Troy Currence

Hi,
Basically when you are attempting to allow traffic from the external public network to some of your servers/hosts you will either use Static NAT or Static PAT
Static NAT is when you bind a single public IP address to be used by only one internal host. This is usually the preferred option if you can spare a single public IP address for your server, meaning you probably have a small public subnet from your ISP.
Static PAT is when you only allocate certain ports on your public IP address and map them to a local port on the host. This is usually the option when you only have a single public IP address that is configured on your ASAs external interface. Or perhaps in a situation when you just want to conserver your public IP addresses even though you might have a few of them.
In Static NAT case you configure the Static NAT and use the interface ACL to allow the services you require.
In Static PAT you only create a translation for a specific port/service so only connections to that port are possible. Naturally you will also have to allow those services/ports in the interface ACL just like with Static NAT.
Again if you can spare the public IP addresses then I would go with Static NAT or if you only have a single or few IP addresses you can consider Static PAT (Port Forward) also.
I dont personally use ASDM for configurations but can help you with the required CLI format configurations. These can actually be done through ASDM also from the Tools -> Command Line Interface menus at the top.
Hope this helps

Sales and Marketing
SAP Best Practices for Chemicals supports the following sales and marketingu2013related business processes:
Sales order processing u2013 In this scenario, SAP Best Practices for Chemicals supports order entry, delivery, and billing. Chemical industry functions include the following:
u2022 Triggering an available-to-promise (ATP) inventory check on bulk orders after sales order entry and automatically creating a filling order (Note: an ATP check is triggered for packaged material.)
u2022 Selecting batches according to customer requirements:
u2022 Processing internal sales activities that involve different organizational units
Third-party and additional internal processing u2013 In this area, the SAP Best Practices for Chemicals package provides an additional batch production step that can be applied to products previously produced by either continuous or batch processing. The following example is based on further internal processing of plastic granules:
u2022 Purchase order creation, staging, execution, and completion
u2022 In-process and post process control
u2022 Batch assignment from bulk to finished materials
u2022 Repackaging of bulk material
SAP Best Practices for Chemicals features several tools that help you take advantage of chemical industry best practices. For example, it provides a fully documented and reusable prototype that you can turn into a productive solution quickly. It also provides a variety of tools, descriptions of business scenarios, and proven configuration of SAP software based on more than 35 years of working with the
Chemical industry.
SAP Functions in Detail u2013 SAP Best Practices for Chemicals
The package can also be used to support external toll processing such as that required for additional treatment or repackaging.
Tank-trailer processing u2013 In this scenario, SAP Best Practices for Chemicals helps handle the selling of bulk material, liquid or granular. It covers the process that automatically adjusts the differences between the original order quantities and the actual quantities filled in the truck. To determine the quantity actually filled, the tank trailer is weighed before and after loading. The delta weight u2013 or quantity filled u2013 is transmitted to the SAP software via an order confirmation. When the delivery for the sales order is created, the software automatically adjusts the order quantity with the confirmed filling quantity.The customer is invoiced for the precise quantity filled and delivered.
Supply Chain Planning and Execution
SAP Best Practices for Chemicals supports supply chain planning as well as supply chain execution processes:
Supply and demand planning u2013 Via the SAP Best Practices for Chemicals package, SAP enables complete support for commercial and supply-chain processes in the chemical industry, including support for integrated sales and operations planning, planning strategies for bulk material, and a variety of filling processes with corresponding packaging units. The package maps the entire supply chain u2013 from sales planning to material requirements planning to transportation procurement.
Supplier Collaboration
In the procurement arena, best practices are most important in the following
Scenario:
Procurement of materials and services:
In this scenario, SAP Best Practices for Chemicals describes a range of purchasing processes, including the following:
u2022 Selection of delivery schedules by vendor
u2022 Interplant stock transfer orders
u2022 Quality inspections for raw materials, including sampling requests triggered
by goods receipt
Manufacturing Scenarios
SAP Best Practices for Chemicals supports the following sales and
Manufacturingu2013related business processes:
Continuous production u2013 In a continuous production scenario, SAP Best Practices for Chemicals typifies the practice used by basic or commodity chemical producers. For example, in the continuous production of plastic granules, production order processing is based on run-schedule headers. This best-practice package also describes batch and quality management in continuous production. Other processes it supports include handling of byproducts,co-products, and the blending process.
Batch production u2013 For batch production,
SAP Best Practices for Chemicals typifies the best practice used by specialty
chemical producers. The following example demonstrates batch production
of paint, which includes the following business processes:
u2022 Process order creation, execution, and completion
u2022 In-process and post process control
u2022 Paperless manufacturing using XMLbased Process integration sheets
u2022 Alerts and events
u2022 Batch derivation from bulk to finished materials
Enterprise Management and Support

Best Practice for 0InfoObjects

Hi,
I need assistance on BI best practices for using 0infoObjects. Currently, we have many 0infoObjects such as 0CostCenter, 0ProfitCenter, 0SalesOrg etc which are used in zinfoObjects like Zcustomer, Zmaterial etc in addition to Z cubes and zODS.
We are starting an upgrade project which presents a chance to convert some of these 0infoObjects to ZinfoObjects so that they can be customized later as needed.
What is the best practice for situations like this? do we take on the extra effort of changing 0 to Z ( I read somewhere this is advisable ) or should we target only some infoObjects which historically change the most.
Thanks,
Kartik

Hi:
Use the 0-infoobjects as they are.
Business Content gven by SAP is pretty good for some modules (e.g., Finance).
Clients pay lot of maney for SAP so that they can use the delivered Business Content as much as possible and then, <b>if needed</b> create new Custom Objects.
When it comes to InfoProviders, its a good idea to copy them to Z-InfoProviders and make new changes accordingly. but, InfoPbjects like Cost Center, COntrolling Area, Functional Loc, Material, etc, etc; just use them as they are. Good luck if you want to create Z-Infoobjects for the above critical infoobjects.
Do you know how difficult it is to get R/3 based hierarchies for Z-infoobjects (again, Cost Center, Fucntional Location, Cost Element)?
Also, you <b>have</b> to use SAP delivred Time Characteristics.
Since you need to use some delivered InfoObjects anyway, it dictates that you have to be careful installing new Business Content.
There you go.
