Hi,
For better performance i want to separate UI logic that is within PAI event and my application logic that is insert operation.
any good idea?? shall i use function module??
Thanks

Hi,
The best way to seperate is to WRAP all your business logic into some ABAP objects class or some Function module and then in the PAI call appropriate methods.
Still you will have the method call in the PAI but atleast the business logic is in a seperate component and you can transport it seperatley.

Validator using logical AND or logical OR

How can I validate multiple TextInputs using logical AND or
logical OR. For example:
If TextInput1 == Null || TextInput2 == Null causes a
validation error if both are null but passes validation as long as
one field is populated or both fields are populated.
John

You could have a Boolean variable that is initially false,
and only becomes true when one of the TextInput becomes populated.
The variable could be set in the TextInput "change" event.
Your validation code would check the value of that Boolean
variable.

How to separate ims-ms and tcp_local channel

Since I have serveral domains in one mail store, now we can separate SMTP channel for each domain. But how to separate ims-ms and tcp_local channel for each domain? Now we are on version 6.0 patch 1
Thanks

I'm sorry, I don't have a clue what you're looking to do. Often folks ask for a way to do something, without telling us what it is they want to do, and the method requested isn't possible.
tcp_local is the channel set up for mail to and from the internet. ims-ms is for delivery to the store. They're already separated.
Please start over, and let me know what your ultimate goal is, and perhaps then, I can help you.
There is no need to separate anything for separate domains on one mail store. . .

How to separate enter GR and return in invoice verification

Hi: guys
I have completed GR for purchase order, and then, vendor send me invoice. however, during invoice check, warehouse return goods to this vendor. so I just want enter GR item excluding the new return item. but sap system automatically propose total Qtys/amounts. I cann't manually change Qtys/amounts.
everybody can tell me how to separate enter GR and return in invoice verification.
someday suggest me use return PO and 161 movetype to deal with this problem. however, I not think this is a good solution.
thank you
Henry

well the main point of u r problem is that u r not able to change the qyantity /value in invoice
but system should allow u to change the quantity and vlaue as per standard sap settings
i think u r user profile is not authorized to do so.........chek the authorization for miro
u can aslo ue invoice reduction option in miro
suppose u r vendor invoice u for 100 pc but u have recived only 89 pc as 20 pc u have already returned then u can use invoice reduction option to change the quantity and value and in this case sytem will genrate the credit memo and invoice
100 pc invoice
20 pc credit memo
and ultiamtely u have posted 80 pc invoice
if any thing not clear then let me know

How to Create Primary DB and Physical/Logical Standby DB on the same host?

Now I encounter a issue. I want to create one Primary DB and one Physical standby DB and one Logical standby DB on the same host.
Create this env on the same host aims to test whether we can using EM Patching DP to apply patches on Primary/Physical/Logical DB successfully.
I try to setup this env but fails. I want to know more related issues about create Primary DB /Physical DB/Logical DB on the same host and how to configure between them.
Below steps is my try:
1. Create Primary DB on the /scratch/primary_db
2. Create Physical Db software only on the /scratch/physical_db
3. Create Logical Db software only on the /scratch/logical_db
4. Using EM Wizard to create physical standby database and logical standby database, and these two targets can show up on the "All Targets" Page.
5. But when using EM Patching DP, it fails and the reason is the listener of physical and logical db cannot configured well.
Issues:
So I want to know about how to configure physical db and logical db's listener using EM or manually?
If the listener name of Primary Db is LISTENER and the port is 1521,and the listener.ora is under the /scratch/primary_db/network/admin directory, then how to config physical db and logical db's listener's name and port?

Hi,
As this a test case then you need to create two more listener for each Oracle Home (/scratch/physical_db & /scratch/logical_db) make sure that they have different names and ports.
Then add the new listeners manually using GC?
Try it and let me know

Logical AND vs logical OR on empty boolean array

Just satisfying a curiousity...Can anyone tell me the logic behind this behavior (LV 7.1,8.0 and 8.2 do it)?
Logical AND on empty Bool Array = TRUE
Logical OR on empty Bool Array = FALSE
Of course there are very simple ways to work around this, but it doens't make sense. If the OR operator is FALSE for a given data set, how can the AND operator be TRUE?
Pic for proof.

How to separate the value and currency

Hi Experts,
We have data in report like this 12545EUR
                                                   24521DM
Now our requirement is separate the value and currency.
Can anybody tell me what i do in Query designer.
Thanks in Advance

Hi
NODIM is used in a scenario like u want find the amount of product then the formula for the amount is price * quantity
AMOUNT = PRICE * QUANTITY
IN this case the unit for PRICE ,let say EUR and for quantity the unit is EA and say we have price value = 10 EUR and quantity value   = 5 EA
if u apply the above value in the above formula , then it leads to the value as shown below,
AMOUNT = 10 EUR * 5 EA = 50 EUR EA
In this case the units for the amount should be EUR not "EUR EA" in this case we have to eliminate the units for PRICE . so that can be done by using the
amount = /BIC/NI_AMT * NODIM(/BIC/NI_QTY)
             = 10 EUR       *   5         = 50 EUR
Hope u got it,
Revert back in case of any query ,
Assign points ,

How to separate the source and the measured current

Hi Everybody,
I'd like to know if there is some way to separate the source and the measured current and just writte an mathematical expression to make a dependence between the source and the said parameter. Thanks in advance.

Sure,
Here is the deal:
I'd like to build a circuit with dependent sources, but instead of connecting the sense of current/voltage, I'd like to know if there is a way to writte a sentence for the source which is dependent of a parameter.
For example:
In this circuit I just wrote an expression for the source and its respective parameter. (8*Io).

in this case how could I separate the header lines from the flat file and update the details to my internal table.
kindly help me on this issue.
Thanks and regards,
M.S.Amirtharajvijay.

Hi Amirthraj,
If the flat file is static (if the content within it is same for all) then use the offset concept. First get the contents of the flat file into an internal table and later find the field that has to be in final internal table within the line, calculate the offset for the line and get the value into an workarea. Finally modify/append the work area into an internal table. Also wait for other experts answers for any other hassle free way to achieve the requirement.

How to separate different views and parts of a single line of business(LOB) universal app for windows 8.1 with many users.

Hello am an intermediate Windows Phone/Store Developer. Am currently in the process of implementing a LOB app that will have three different types users, an admin, a student, a teacher . Depending on how a user logs in i would like certain pages to be exposed
to them and the rest to be hidden. The app will also store data temporally on a local db then sync regularly to an azure database(Can the recent entity framework 7 that supports store/phone apps allow code first databases or are there features still not fully
accessible in WinRT apps)...This i believe can handle but also kindly point me out to existing implemented resources/examples i will appreciate very much.
What am finding problematic is how to consume different app data stored by various users logged in for these different views. Will i need an asp web api is it really necessary cause i want to avoid it cause i have about three months to do it. I do not want
to create three different apps and one ASP Web AP, i want one single app and an api if possible, i know windows usually sandboxes apps hence app to app communication will be hard if not impossible. So my question is, is it possible to implement different
user session management with a login (Windows Live ID) which i can abstract various parts of the app from them depending on the users login id in the app. E.g How can an admin logged in the same app as the student have access rights to certain pages in the
app that a student will not see. How do i route different users to certain pages and can isolated storage store these persisting as a setting.
How can i know which login id belongs to which of the three users? How do i then assign different access to different controls of the app with their id,provide custom views routes,access right,session management. I think i can do these without an ASP Web
API is It wise? Building pages in the apps is easy but i want users to see different views of the app instead of one standard app depending on there login id, how can the NAVIGATION URI be used here. How can azure and features like active directory,azure mobile
services. I know i have repeated the same things over and over and these might be complex for a free advise but as a windows dev these is my one stop shop. Any one with a view on how to approach these kindly show me the best directions. Thanks guys in advance.

I suggest you have a look at this sample.
https://code.msdn.microsoft.com/windowsapps/ListView-Interaction-ac044c3c. MainPage provides the framework to hold the content. At runtime, we create the Scenario collections and then bind to control. This approach can help you determine the type of users
and provide some appropriate pages at runtime.

Separate UI logic and database operation

Hi,
For better performance i want to separate UI logic that is within PAI event and my application logic that is insert operation.
any good idea?? shall i use function module??
Thanks
Regards,
Virat

Hi,
There will not any performance issue as such as all the code will be executed by the same Dialog workprocess in the application server.
But it is alwys good to keep you flow logic and application logic seperated, so flow logic just calls the methods and the methods are in a different component like a static method of a class or function module in a function group.
Best thing is Function Group as you can have screens in a Function pool.
