in which situvation you will use interface controller and custom controller?

Hi rafi,
Custom Controller Custom Controller is as same as the component controller, here we can write the business logic.
Custom Controller means developer can create multiple controller denpeing up work.
By using component controller we cant create multipule contrllers. when we create the DC that time it will be created automatically.

I am wondering if anybody knows an app which allows you to use your iPhone as a CCTV camera so I can view what is going on. Please if you know any app which allows you to use your iPhone as CCTV camera. Thanks I am really grateful.

There are serveral brands and models of security cameras, baby monitors and nanny-cams that have apps in the the app store. They are designed to accomplish exactly what you are describing. Each brand of camera has its own app.

Code example using interface controller ?

Hi, guys:
I have a question.
In CRM UI, I need to integrate one component with another component, and I want to pass the value from 1st component to 2nd component using interface controller. Does any one who have done this before and have a code example?

My question is when you will use the android OS? S...

my question is when you will use the android OS? Stop Symbian & Windows Please

ITs time to use Android OS for NOKIA Company because people now want expandable memory slot (Mirco SD card ) like Andriod Phone and I heard most windows phone does not support Micro SD card and Bluetooth for file transfer is that righti.e. Bluetooth is only there for listening songs not for file transfer)
In case of Symbian OS is actually good OS for low cost model means below 4000 Rs. mobile phones only not for smart phone
Symbian OS doesn't reach to the Android OS because even if Nokia try to do so.. but their prices are more than Android phone with same features and now if we compare Micromax Bolt A51 and new NOKIA ASHA 501 see the difference refer http://www.gsmarena.com/compare.php3?idPhone1=5428&idPhone2=5445 this link
HENCE WITH THIS CONCLUSION I WANT TO TELL NOKIA COMPANY THAT EITHER THEY REDUCE THE PRICE OF THERE SYMBIAN MOBLIE PHONES OR IT'S TIME TO SWITCH TO THE ANDROID OS DUE TO WINDOWS PHONES HAVE MORE DRAWBACKS THAN ANDROID OTHERWISE THERE IS NO FUTURE FOR NOKIA COMPANY TO RAISE AGAIN IN THE CURRENT MARKET
WISH YOU BEST OF LUCK NOKIA COMPANY FOR KEEP CONNECTING PEOPLES......I HOPE YOU CHANGE YOUR MIND...

Using Interface controller in OCA application

Hi,
My requirement is to pass information and screen control between two components in two different DCs.
My parent DC Component has to pass information to my child DC Component and also call the view assembly of the child DC.
I am using CE7.1 SP07 PAT003.
In my child DC I have created a component Interface Definition say ChildInterface. In the context of interface controller of ChildInterface I have added a string attribute. ChildInterface also has a view container.
Now in my Child component I add ChildInterface as my Implemented Interface. I map the window of the child component to the ChildInterface. To the view container I add the default view of the component.
Now I have created a public part and added the ChildInterface as an entity.
I add a dependency in my Parent Component to this child DC's public part.
At design time I can access my ChildInterface's context from my parent component. However, while adding a link from parent default view to ChildInterfaceView, it gives me an error. however on reload it suppress the error but doesnt open the java editors.
While trying to deploy the applications it gives me a deployment failure message.
Following is the trace-

please do attach the trace files..
Meanwhile , just check the way you have implemented the interface and the interface defintion of achild node are correct.
Once the implementations are correct,there should not be problem in deployment.
Let us know if you need more info on interface definton creation ...

Which temp tablespace will used during the import (impdp) ?

Oracle version : 11.2.0.3 on Solaris
We have created an empty schema called MLDT_FN and set its default temporary tablespace as TEMP_MLDT. We usually use SYSTEM user to do exports (expdp) and imports (impdp)
During a schema level (or table level) import to MLDT_FN schema, which temporary tablespace will be used ?
Will it be
the default temporary tablespace of SYSTEM user which runs this impdp job
or
the default temporary tablespace of the newly created MLDT_FN schema which is being to imported to

It will use default temp tablespace of schema.

In which situation we will us e BAPI and IDOCS

Hi friends,
pls explain in which situation we will us e BAPI & IDOC, why ?
Regards
Jagadeeshwar.B

Hi,
Both are used for data transfer.
BAPIS are interfaces which enables to communicate with sap aswellas nonsap systems. IDOCS are intermediate documents sent between sap and nonsap systems.
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.
But BAPIs are synchronous ( i.e. the systems must be online) whereas IDOCS are synchronous ( ie. both systems need not be online .
we can make bapis asynchronous using the IDOCS.
thanks and regards.

Can you print using both USB and Wireless on HP M175nw?

I am having a problem with my new LaserJet 100 colorMFP M175nw. When I initially set it up with Setup wizard, I selected the "USB" option, since that was how my old printer was hooked up to the computer. That worked fine and the printer works perfectly with my desktop. Now I can't figure out how to also set up the printer to be used wirelessly. I specifically bought this printer because I wanted to be able to Airprint from an ipad. I've tried several of the fixes listed on this website, but I'm not able to get a list of wireless networks to appear on the printer's menu. I am using a Linksys wireless G router, which is hardwired to my desktop, but which I use to wirelessly access the internet with my laptop and ipad.
What is the best way to be able to use the printer with my both my desktop (non-wireless), laptop, and ipad (both wireless)? Can I leave the printer hardwired to my desktop with a USB AND connect the other devices wirelessly? If so, what is the best way for me to connect the printer to my router - wirelessly or wired? What steps do I need to take to do that and get the printer connected?
Thanks for your help!

Hi,
Before Christmas 2011, I ran few tests and I've posted elsewhere on this forum. My printer is a different model but I believe same technology. My tests indicated we can connect printer using BOTH wireless and USB. Printer will show busy/not available during direct print (ie USB) but it knows job(s) is/are on the queue and print after that.
One thing I could not test successfully: scan and print at the same time.
Regards.

Which accounting entries will getupdated in STO and Subcontrtaction?

Hi
Can anyone tell me which are the accounting enties will get updated at the time of GR for the below to processes
1. For Subconatracting
2. STO (Plant to Plant transfer)
Best Regards,
Sairam.

Hi,
You check an invoice for a subcontract order in the same way as for a standard purchase order. Additional account postings do, however, occur if a price variance has occurred. These postings are shown in the following example.
Postings for a Subcontract Order
In this example, a subcontract order was created for the end product "ASSEM-1". The components COMP-1 and COMP-2 were provided to the subcontractor.
Purchase order
50 pieces of material ASSEM-1 were ordered. The subcontract price is $10/piece (total value = $500).
The following components were provided to the subcontractor:
15 kg of the component COMP-1
5 pcs of the component COMP-2
Goods receipt
The subcontractor delivers 50 pieces of material ASSEM-1.
At goods receipt, a consumption posting for the components provided to the subcontractor is automatically made. It is valuated at the price from the material master record, for example:
15 kg of the component COMP-1 at $20/kg = $300
5 pcs of the component COMP-2 at $30/pc = $150
The goods receipt is valuated with $950. This is calculated as follows:
The subcontract price (50 pcs * $10/pc = $500) and
Value of the components ($300 + $150).
Invoice receipt
The vendor (subcontractor) sends you an invoice for the subcontract work. However, the price is $10.50/pc. Therefore the invoice is 50 pieces ASSEM-1 * $10.50/pc = $525.
Posting Schema for Moving Average Price Control
In this example, the following postings are made at goods receipt and invoice receipt, if the material (end product) is valuated at moving average price.
Postings
At goods receipt
At invoice receipt
Vendor account
   525 -
GR/IR clearing account
500 -
500 +
External service account
500 +
25 +
Stock account: end product
950 +
25 +
Change involving stocks
950 -
25 -
Stock account: comp.
450 -
Consumption account
450 +
Posting Schema for Standard Price Control Without Price Differences
For materials (end products) with standard price control also note that
No price differences are posted if the total of the external service value (for example, $500) plus the "material to be provided" value (for example, $450) varies from the value at standard price (for example, $1000). Posting of a price difference is not required because each posting line has its own offsetting entry.
No posting lines are created on the stock account or on the stock change account when an invoice is received.
In the above example, the following postings are made for a material with a standard price of $20.
Postings
At goods receipt
At invoice receipt
Vendor account
   525 -
GR/IR clearing account
500 -
500 +
External service account
500 +
25 +
Stock account: end product
1000 +
Change involving stocks
1000 -
Stock account: comp.
450 -
Consumption account
450 +
Posting Schema for Standard Price Control With Price Differences
However, if you wish to generate a price difference posting in those cases where the manufactured material is managed at standard price and the standard price varies from the receipt value (externally performed service + value of components + delivery costs), you can configure this in the Customizing system of Inventory Management.
In the above example, the following postings (including price differences) are made for a material with a standard price of $20.
Postings
At goods receipt
At invoice receipt
Vendor account
   525 -
GR/IR clearing account
500 -
500 +
External service account
500 +
25 +
Stock account: end product
1000 +
Change involving stocks
950 -
Price difference
50 +
Stock account: comp.
450 -
Consumption account
450 +
Reg STO please inform in details entries in case plant to plant or between co-codes?
