2 tier model or 3 tier model

Which one is better for BC4J JClient application ? using 2 tier model or 3 tier model ?
Thx,
Ricky H.P.

Ricky,
it depends on your business case
If you need to share business logic with other web applications or if the client PC is not as powerfuly as it should be, then using a three tier architecture is what I would recommend.
If you are free to choose with dependecies then a two tier architecture is what I would prefer. However, if you need your application client to be able to run offline /stand alone) against a local database, then two tier is what you should do.
My personal preference is to position JClient in a two tier architecture running on Java Web Start.

Demand Forecast to rollup from Tier 3 warehouses to Tier 1 main plant

Hi ,
I would like to find out if there are any possibilities to roll up demand forecast from Tier 3 warehouses (nodes) upwards to
main Tier 1 warehouse / plant (root)
please suggest ideas/ inputs
1)Any BI Data Load methodology need to changed or if
2) Any APO config needs adjustment

HI,
I am now confused on what you actually want to do.
If you want to plan in SNP, then since you are maintaining inforecords in ECC, you need to create integration models in ECC and CIF the inforecords. Each inforecord should come into APO and create transportation lanes. You shouldn't have to manually create transportation lanes in APO. You would how ever need to maintain the means of transport in each of the lanes from plant to DC Tier I to DC (s) Tier3.
When you run Heurisitics, the demand is aggregated to Tier I DC and then to plant.
If you maintain the forecast for the Tier I DC and Tier II DC(s) in DP, you can just release the forecast at these DC levels.
If you want to run statistical forecast at the Tier II DC(s), then you need the demand history in DP for each of the DCs.
Is this what you are trying to do? or are you trying to rioll up demand in DP. If you want to roll up demand in DP, I am not sure what the need is. Can you explain?
For any further questions, please give more details; examples would help.

1. The scrolling, as far as I've been able to determine, is by using the slide bar to the right of most diplays. There are no up or down arrows that allow slow movement
2. The top and botton toolbars are not visible. The top one appears when you point the arrow to the top of the screen but the same doesn't work well if at all pointing the cursor to the bottom.
3. When downloading, something jumps to the upper right of the screen. I could point and click it and get a diplay if my downloads. I was attempting to fix some of the above. Now the little thing jumps off the screen and I can't get to it.
4I was trying to installMacBook Pro EFI Firmware Update 2.3. I got message it couldn't be installed on my system.
5. The red yellow and blue bullets that allow shutting down, minimizing and maximizing are missing on most open windows.
Can you do something about these problems
It's problematical that one can't communicate directly with Apple to resolve these problems
<Edited By Host>

1: I'm scrolling this page right now using the arrow keys.
2: Press the escape (esc) key to exit full-screen mode. Select Apple menu > Dock > Turn Hiding Off.
3: ???
4: That's because you downloaded an update for another model.
5: See 2.

Apple states that (of the MBP lines) it has to be from Mid/Late 2007 or later. yours seems to be right on the line.
Apple says
If you are running Lion, you can find out if your current Mac qualifies by clicking the Apple icon at the top left of your screen, choosing About This Mac, then clicking More Info.
you must also have the latest version of Snow Leapord or Lion

CAF Model vs Adaaptive RFC Model

hi all,
What is the difference between<b> CAF model with Adaptive RFC Model</b>.
Regards,
Sukanta

Hi,
CAF Model and Adaaptive RFC Model both are different.
In CAF you are creating Entity Service , Application service and doing modeling in entity service and application service as per your requirement and you can also expose the modeled services as web service for using from other application like as Web Dynpro. In CAF GP you can also do the modelinh of workflow.

http://help.sap.com/saphelp_nw70/helpdata/en/32/d58041a17e060de10000000a1550b0/frameset.htm
But RFC model is like that it is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.

Difference between webservices model and adaptive webservices model

hi
Can any one explain me regarding Difference between webservices model and adaptive webservices model.
Thanks

Hi,
In old WS Model, ithere was no concept of logical destinations.
There if you are using a WSDL located on a server and if the location of the WSDL
changes, your application won't run. The deployed application using the WS Model will have trouble finding
the WSDL. As a result you'll have to again import the
model. Moreover old WS Model does not have re-import functionality.
But incase of AWS Model, you can desine logical destinations and even if the location of the WSDL changes, all you have to do is change the new url in the Visual Admin and not import the model again.
You can visit the following link for more details:

Migrating Relational Model to Object-Relational Model

Hi,
Can someone direct me to appropriate tutorial/examples in migrating spatial relational model to object-relatonal model.
I have the following tables in the relational model:
ROADS
ROADS_SDODIM
ROADS_SDOGEOM
ROADS_SDOINDEX
ROADS_SDOLAYER
What tables would I need to create in the object-relational model?
Can someone advice me on how to use this function sdo_migrate.to_current?
Thanks in advance!

There are a number of Object Oriented databases out there, with Gemstone perhaps the best known. Also, Oracle, and other RDBMS vendors are adding more object oriented features all the time.
However, there are some downsides to OO databases. One of the biggest is that it is often really difficult to query the data directly. All interaction with the database needs some sort of mapping layer to instantiate the objects and get their attributes. It is also difficult, and sometimes impossible, to generate ad hoc queries that try to look at the data in a way that does not match the object model, something that is relatively easy in a well designed relational model.
Finally, object oriented databases represent a more or less one to one mapping to a currently popular programming paradigm. What happens to the data when the next great programming paradigm (foo perspective) comes along? Will the foo prgrammer be able to easily read the objects in the OO database? Probably not. Will the foo programmer be able to easily read the relational data? Almost certainly.

How do I add InDesign's Object model to ESTK Object model viewer?

I am new to InDesign scripting, and was told that I could view InDesign's DOM in ESTK's object model viewer. The problem is that my ESTK does not show InDesign Object Model in ESTK's model selector drop down! InDesign DOM is not there in the drop down list.
How do go about adding the ID DOM to the list?
BTW, I am on CS6.

this might help.

SQL Data Modeler reporting repository data model

SQL Data Modeler (SDM) reporting repository data model
I exported several models to reporting schema and reviewed the reports. So far so good. The reports I need are not included so I'm creating my own. I imported the reporting schema to SDM to explore the model and see how to join the tables. Has anyone already done this exercise and produced a data model for the reporting schema with primary keys, foreign keys and relationships? It would save me a pile of work if I could download the model and import it to SDM?
Gerhardt

Thank you Philip,
We are doing reports in TOAD and Cognos 8.
So far so good. One of the pieces of information I need out of the Oracle Data Modeler reporting schema is the columns in foreign keys. Foreign keys are not usually enforced in datamarts but data analysts must know what the foreign keys are to join tables.
There is a notation in Relational Model Elements.pdf "Foreign keys of DMR_CONSTR_INDEX_COLUMNS table are not valid since one column is used to refer to objects in two different tables"
This begs the question: Is there a valid foreign key in DMRS_CONSTR_INDEX_COLUMNS to join it to DMRS_FOREIGNKEYS or is the model documented incorrectly?
The repository adds tremendous value to Data Modeler.

Volume control keys not functioning. PC model: s5268hk, with keyboard model: KG-0851

I am using a desktop slimline model: s5268hk, with keyboard model: KG-0851. I don't remember what program I installed that caused the trouble but anyway, right now- it is not functioning like the usual. I re-installed the driver from HP support yet nothing has changed. I appreciate any advice you can provide, thanks to everyone in advance!

You may have to go back to a known good system restore point.
Right mouse click on my Computer, select properties, then advanced system setting then restore. When you get to the restore window, check the box to show all available restore points and pick a date where your know when your PC worked correctly.
If you are using a Norton AV product then turn off "tamper protection" before you attempt a restore or it will fail.

Hi HarmitClaire,
Welcome to the Apple Support Communities!
I understand that your MacBook Air is not charging as expected. In this situation there are troubleshooting steps that I would recommend. Please use the attached article as a resource for steps to help you resolve this situation.
Mac notebooks: All about batteries - Apple Support
My battery is not charging
Confirm the correct wattage AC adapter for the computer. A power adapter rated for a lower wattage than is required for the system may not reliably charge the computer. For assistance identifying the proper adapter, review Intel Based Mac notebooks: Identifying the right power adapter and power cord--US. Additional adapter troubleshooting is available in Troubleshooting MagSafe adapters. If issues persist please reset the SMC.
Best regards,
Joe

Product Modelling Environment - Variant Configuration- modelling configura

Hello all,
I have a very important question for which I am trying to find answers. I ahve been researching for the last 2 days continuously
and now I kind of confused.
I need an answer tot his at the earliest possible
And I am struggling to differentiate between PME and product modelling in crm , is it the same?
When Ilook in this link ,it says;
http://help.sap.com/saphelp_crm70/helpdata/en/ed/bfb2ce6a6a46af92172c4ff901f125/frameset.htm
NOTE
This function in the WebClient user interface (UI) replaces the Product Modeling Environment (PME) application, which had to be installed separately.
What does this mean?? does this mean that modelling configurable products is different from PME?
can Product modelling be done in crm as well as ERP?
Could u please let me know
Thank you
BR
Riya

Hi Vinod,
Please find below a brief:-
A product model contains the configuration model data relevant for one product which is a server based Architecture.
-A knowledge base is a container for data and can contain many PMEs
-PME is available in Product page
-Need to insert and create a new product model and select the model and enter product related data.
-Create KB's
-Will have to define the characterstics and values and assign to class
-Product model hierarchy shows the model in tree structure.
-After you created the hierarchy with all details you can simulate the configuration as a result titile simulator pops up where you can see the status and Variants and your current selection.
