Essbase vs. Relational Data Warehouse (Which one is the fact table in DW)?

Guys, thanks in advance for your feedback but below is a simple question i am trying to get feedback on. I am trying to compare an Essbase cube to Relational Data Warehouse containing the same set of information:
Essbase Dimensions
Time, Account, Product, Scenario (making it easy)
Relational Data Warehouse
Time (dim), Account (dim), Product (dim), Scenario (Fact table)
OR
Time (dim), Product (dim), Scenario (dim), Account (Fact Table)
Which of the relational lines is correct? Is Account the fact table? or Scenario the fact table? Account will contain your usual P&L accounts. Scenario will contain your usual Actual, Budget and Forecast scenarios.
Thanks,

I am so not a DW guy, it's amazing, but I've never let little more than a brush with a product stop me from posting...
Wouldn't all of your dimensions need to be in your fact table? How else would you join from the fact table to the dimensions?
In either layout, wouldn't you have the keys for Product, Time, Scenario, Acount, and then data in the fact table?
Or are you talking about the last dimension in your layouts be the columns? If that were the case (and I don't know that it is), I would guess that Scenario changes less, so it would be in columns, although I can definitely see that not being efficient as you are likely to pull all or some of the Accounts for a given time, product and scenario versus all of the scenarios for a given time, product, and account.
I'm really curious about this as I am just the consumer of star schemas, never (thankfully, and obviously, given the above insane ramblings) the designer of them.

BCS Data Model (which one is the best)

Hi,
We are implementing SEM-BCS 6.0 with SAP BI 7.0.
We have 2 possibilities for a data model and we need help to decide which one is the best.
The first possibility is:
1)       SAP ECC 6.0:
a.      Define 2 (two) charts of accounts (company chart of accounts and consolidation chart of accounts) that are mapped/linked in transaction FSP0;
b.      Define Balance and an Income Statement hierarchy for the group/consolidation chart of accounts;
2)       BW (BI 7.0)
a.      In BW we also have both charts of accounts, with a Balance and an Income Statement hierarchy for the group/consolidation chart of accounts. These ones were replicated from source system SAP ECC;
3)       SEM-BCS 6.0
a.      IN BCS we update the Financial Statement Item automatically based on/equal to consolidation chart of accounts (and not based on Balance and Income statement);
b.      For reporting issues, we will define BW workbooks, based on the Group Balance and Income statement, for Consolidation reporting. In resume, we will have the Balance and an Income Statement hierarchy for the group/consolidation chart of accounts, created in SAP ECC, replicated in BW in order to report consolidated data.
The second possibility:
1)       SAP ECC 6.0:
In R3 we only have the company chart of accounts. For consolidation purposes we will define a Balance and an Income statement item hierarchies, one for legal report and the second one for management report, which the superior nodes (items) are the aggregation of G/L Accounts (below nodes).
2)       BW (BI 7.0)
In BW we will replicate the Balance and Income Statement that was created in SAP ECC.
3)       SEM-BCS 6.0
In BCS we would have to:
                                                  i.      Create automatically the Financial Statement Item, based on the items of Balance and an Income Statement hierarchies, which would be a concatenate of the two item hierarchies.
                                                 Or
                                                    ii.      Create 2 Financial Statement Items, where which one would depend on the balance or the income statement hierarchy.
Which of the possibilities is the best?
Having 2 charts of accounts (company and consolidation) or just have one chart of accounts (company) and have a balance item hierarchy consolidated and create the financial statement item in BCS having this hierarchy in account and not a consolidation chart of accounts?
In our opinion the first scenario is the best one, because is seem to be more flexible and as we have the intention to use SEM BPS in the next year, for budget purpose. Furthermore, we think that with the first scenario we can have a FS Chart of accounts (in BCS) that is not dependent of reporting purposes (based on Balance and Income statements).
Is this interpretation correct?
Thanks

Hi Ricardo,
Yes, The first one is the best choice and it is the way to work.
SAP has given some How-to documents, which are available in service market place. These documents also suggest almost same path as first choice.
Thanks

Can date be included in the fact table as a measure?

Dear All,
I have to migrate a database form relational model to dimensional model. It a kind of human resource database. I don't know what MEASURES should I keep in the fact table. There are only dates, like date the employee joined the institution and the date he will leave. Most of the other fields are non-numeric. well date is also non-numeric but we can calculate the duration the employee worked from these dates.
What do you suggest?

I'd be careful about adding a "measure" of duration worked (be it days, months, years - doesn't matter). Causes lots of churn. For example, if you choose a measure of "duration_worked_in_days" - every single row in the fact table would be obsoleted every single day....
What types of questions do you expect the fact table to answer?
I'm working on a HR mart right now, and my fact data is around pay rates (not actual pay), i.e. annual salary, hourly salary, etc. My records also have two "date" dims - effective start date and effective end date. Meaning if my annual salary is $50 a year between 1/1/2008 and 12/31/2008, that's what the row shows. When (or if) I get a pay raise (/cut), the "current" record gets end dated, and a new record inserted.
When you say that a fact table "must" contain measure columns - I assume you're using the actual OWB fact / dimension objects, vs. just tables? Very common in a HR data warehouse to have a "factless" fact table.
Hope this helps,
Scott

Federating Essbase and Relational Data in 11g

Hi,
I am trying to display Time Entry measures from both Essbase and Relational data source (OLTP) in one report.
The People hierarchy in Essbase has 3 levels and I mapped the 3rd level (Gen3 People - Member Key which is actually the Employee Id) to Employee Id column in OLTP. I cannot map the other levels to OLTP because there are no columns that match.
When I create a report with the ff fields: Gen3 People Member Key, Essbase Measure, OLTP Measure, I am seeing correct values. But when I add Gen3 People, the OLTP Measure column becomes blank. When I add Gen2 People, I am getting "No fact table exists at the requested level of detail".
Does this mean that I also have to map Gen2 People and Gen3 People to OLTP before I can use them in my report?
Thanks for the help!

Hi,
Thanks a lot for the help.
I am currently facing following issues in integration.
1. In my Essbase outline , the child level has some aliases. So when I import in OBIEE, I am getting the alias value instead of the actual. How to get the actual data in OBIEE?
2. If I am using external data for only one dimension, I am getting the report generated,but all the measures like sales returns no value. But If I am using the sales and some existing cube dimension column, I am getting the values
3. Inorder to use the other dimension, I followed the creation of total level and added the dummy fact. Still I am getting error 'Unable to navigate requested expression'
Thanks in advance,
Many Thanks,

Your first task should be to just be able to send commands to the instrument. Do as Dennis suggested and download the drivers for the instrument and get familiar with them. Build up small VIs that do little tasks with those drivers so you can get used to them. Then worry about your main interface.

TS4006 I have several iphones on find my iphone. How do I know which one is the correct iphone. None of them are labeled Iphone4 or 5 etc.

I just had my iphone stolen from me. In the past I have always set up my phones an ipads on to the find my iphone service. I have never deleted them from the find my iphone account and now I have 3 iphones showing and 2 ipads. How can you tell the difference when none of them are labeled as Iphone 4, iphone 4s, iphone 5, etc. No dates are shown as when purchased so it I can't figure out which one is the correct iphone to put on lost mode and send message to.

Deleting on one device does not affect another device.
You can delete the App's on the iPhone and nothing will happen to the ones on the iPad.
1. You don't need to.
2. Settings->Cellular->"Use Cellular Data For" will show the data usage for each App since the last statistics reset
3. Settings->General->Background App Refresh Will show which Apps are allowed to get data in the background
4. It restricts it to Wifi. If the App requires internet access and Data is turned off, it will have to wait until the device is connected to a wifi network.
5. Nope, You just use up battery since the BT radio will continuously look for nearby BT devices.
6. The Personal Hotspot uses your cellular internet connection from your phone or other cellular device; whether you consider that secure or not I cannot say. It also depends on what you are doing while connected to the Hotel's wifi. I would not do online banking while on vacation though.

Session method and call transaction methos which one is the sap recomonded

hi
PLease give me the answer to these questions.
session method and call transaction methos which one is the sap recomonded why .
2) if we want to maintain BDC program in all the systems.wt to d0

Hi Revethi,
Here is the difference between the Session and Call Transaction method.
Session
Session method supports both small amount of data aswell as large amount of data
2) data processing is asynchronus and data updation is synchronus.
3) it process multiple apllication while perfomaning validations.
4) in session method data will be updated in data base only after processing session only.
5) system provide by default logfile for handling error records.
6) it supports both foreground aswell as background process
in bdc we use FM ... bdc_open_group " for creating Session
bdc_insert " adding transaction and bdcdata table for updating database
bdc_close_group " for closing Session
Call Transaction
Call transaction exclusively for small amout of data
2) it supports only one apllication while perfoming validations
3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.
we can create logfile by using structure....BDCMSGCOLL
4) it doesn't support background processing.
5) data processing is synchronous and Data updation is Synchronous( default), in
this method also supports daya updation in asynchronus process also.
Syntax:
Call transaction <transaction-name> using BDCDATA
mode <A/N/E> update <L/A/S>
messages into BDCMSGCOLL.

Which one is the best practice!!

hi all,
i have one doubt with the lov
can we show the data in the LOV by decode function or its better to write two LOV's based on the condition.
which one is the best practice.
right now i am using decode function. according to the condition the data will come in the LOV.
Thanks..

can we show the data in the LOV by decode functionAs you already do, you can.
its better to write two LOV's based on the condition.It depends. If its a complex lov and only one column varies based onsome condition, it might less work to use just one lov. Personally, i prefer two different lov's

Which one is the best way in migration from sap bpc ms 5.1 to nw7.5

Hi,
I am doing Migration project from SAP BPC MS to NW.
In this which one is the best way migrating By manually or By using SAP Migration tool.
What are the merits and demarits migrating by manually.
The data is moving from MS to NW as it is by using sap migration tool.
Could you please answer my questions as early as possible.

Hi,
You would need manual effort anyways. Some of the objects are not either migrated or you need to update manually after the migration. Example, reports have to be modifed and as they may not work due to some of the options.
Also your packages, script logic etc have to recreated. So its upto you as the migration toosl takes across your appset, applications, dimensions and the master data etc. The manual involvement is inevitable. You need to probably take what the tool allows you to do and make manual corrections for the objects that are not supported.
Thanks,

Which one is the best way to collect config and performance details in azure

Hi ,
I want to collect the information of both configuration and performance of cloud, virtual machine and web role .I am going to collect all these details using

Hi,
There are four main tasks to use Azure Diagnostics:
Setup WAD
Configuring data collection
Instrumenting your code
Viewing data
The original Azure SDK 1.0 included functionality to collect diagnostics and store them in Azure storage collectively known as Azure Diagnostics (WAD). This software, built upon the Event Tracing for Windows (ETW) framework, fulfills two design requirements
introduced by Azure scale-out architecture:
Save diagnostic data that would be lost during a reimaging of the instance..
Provide a central repository for diagnostics from multiple instances.
After including Azure Diagnostics in the role (ServiceConfiguration.cscfg and ServiceDefinition.csdef), WAD collects diagnostic data from all the instances of that particular role. The diagnostic data can be used for debugging and troubleshooting, measuring
performance, monitoring resource usage, traffic analysis and capacity planning, and auditing. Transfers to Azure storage account for persistence can either be scheduled or on-demand.
To know more about Azure Diagnostics, please refer to the below article ( Section : Designing More Supportable Azure Services > Azure Diagnostics )

How to add dynamic data type as one of the terminals of a Custom VI

Hello,
Can anybody tell me if it's possible and how to add a dynamic data type as one of the terminals of a sub-VI? I would like to have a terminal that I can connect signal from DAQmx to my sub-VI. Thanks.

Here is one of the coolest things about LV, and one of its major advantages over languages like VB - it has automatic memory management and it compiles whenever you make a change. This allows you to be very free in the way you handle data and change your code. In this case, you should note the small gray dot that appears when you wire the dynamic data into the Array of Waveforms input. This gray dot means that LV coerces the source data type (DDT, in this case) to the target data type (Array of waveforms). If it wouldn't match, you would get a broken wire, the VI couldn't run, and if you hover over the wire or press the broken run button you would get an exact description of the error. Cool, eh?
This can also be seen in other things. For example, you can change an array's data type or number of dimensions by simply doing it. This will automatically be reflected anywhere the array is called in the program, and if anything won't match, the VI will be broken. If you change the # of dimensions of an array, any array function which that array is wired to will adapt. This allows you to be very safe in the way you write code, because you have LV watching all that annoying stuff for you. You don't have to worry about misspelling a variable here (for the most part).
One important point about coercion - it does take processor power. This will usually only be evident in large arrays or loops, but it is an important point. Another thing is that coercing numeric types can cause you to lose data - coercing a DBL to a U16, for example, will cause you to lose all the fractional data.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

Can any one tell me if I am using Hirarchical ALV for outputting the data, and I have to filter out the output data on any one of the column in the Hirarchical ALV, Is it possible ?
Can we filter out the data on the basis of field which is not the key field in the Hirarchical ALV?

Adobe Cloud has 2 different Muse programs.... how do I know which one is the newer better version?

So I am new to Muse, and my Adobe Cloud has 2 different programs from Muse... how do I know which one is the newer better version?
One Must program (Muse CC 2014.2) has a black background when working on it... it looks like other Adobe programs such as Photoshop.
The other one is light color (Muse CC) very similar to the black color Muse on functions.....
One of the difference I notice is that the light color Muse has a few widgets in the library, while the black background Muse seems to have an empty library
So... why are there 2 different Muse programs in my Adobe Cloud?

Hi
The latest version of Muse is 2014.2, so you need to uninstall another version of Muse manually.
regarding the items in Library, you can add items in your library manually, as shown in this article
Adobe Muse Help | Organizing and reusing design elements using Library panel
Please let me know if you have any other query.
