Simple types and structure

Hi
can any one tell me Difference between simple types and structure ?
Thanks,
Kiran

Hi Ravi,
As my concern there is difference between simple type and structure.
1SIMPLE TYPEit behave as TYPE proprty of value attibute .suppose you will create on value attribute as simAtt.then you can put that simple type in your attribute TYPE property .actualy it treated as data type like string,integer........
one more thing you want to change data type in your application then you will create SIMPLE TYPE..then put it TYpe property of value Attribute
Ex--you want to change the format of double value using "," then you will change only by using simple type.
STRUCTURE---Basically it use for creating for context value node in any context of controller(View,component )if you creat one structure then add number of attribute .when you create context value node then you binding the structure then automatically it will populate with value node as structure name and attribute .
SIMPLE TYPE---only put as Data type of Attribute and simple type also use within Structure at time of creation
STRUCTURE---you can use for DAta type of Apptibute..
thanks

Line type and structure.

What is the difference between line type and structure?
one real time use of both.
instead of line type we can directly use the corresponding tables.
Points assured.
regards,
Prabhu.

Hi
The line type of a table type can be defined by:
Specification of a type that already exists (data element, structure, table type, table, view) whose properties are then copied as properties of the defined table line.
Direct type input, where data type, number of positions, and, if required, decimal places, are entered directly.
Specification of a reference type.
structure
The table category defines how the logical table description defined in the ABAP Dictionary is represented in the database.
There are the following table categories:
transparent table
structure
append structure
For internal purposes, such as storing control data or update texts, there are in addition the following table categories:
pooled table
cluster table
generated view structure

Simple Types and Context Attributes

Hello All,
Can someone be kind enough to explain the difference between using a context attribute and a Simple Type ? For example... what's the difference (and I am sure there is ) between a context attribute "Name" that is declared to be of String type and a simple type "Name" that is of built-in type String ?

UCCHECK error in upgrade: Data type and structure not mutually convertible.

Hi ABAPers,
We have upgraded our system from 4.6c to ECC 6.0. We are at the unicode check stage. I am getting an error " 'V_LEV' and 'T_RES_TOTALS' are not mutually convertible in a Unicode program."
The structure of T_RES_TOTALS is like this:

Simple type of type integer

Hi All,
I have create simple type which is of type integer. And i have set the maximum and minimum length for the simple type which is bounded with the input field. When i try to display it, it displayes with ",".
Example 70,000,000.
My require is to remove the commas in between the number. Is there solution for this.
Regards,
Revathy Madhavan.

Hi Revathy,
the display of numbers is localized, here in germany I see "70.000.000". So whenever you change the behaviour, consider that you skip the automated localization provided by sap.
That said: Open your simple type and go to the "Representation" Tab. in the right upper corner, enter "#" into the field format.
Problem solved.
If you want to know more, read the java api of NumberFormat which describes various options for Number presentations based on String patterns.

Simple type enumeration access

Hello colleagues,
while creating a data dictionary type, you can define an enumeration with keys and description texts. Additionally you can let the WD generator to create the class representation for this enumeration. So you can use it in your code.
The generated enumeration only provides the key constant value (enum.getName()) but doesn't bring the description text. Is there any "official way" to read it in code providing certain locale?
I know, you can create a context attribute of this simple type and go for the following expression:
wdContext.nodeTableLine().getNodeInfo().getAttribute("attr").getSimpleType().getSVServices().getModifiableSimpleValueSet()
but I can't imagine the WD doesn't provide any context independent way for this simple operation.
Regards
Dimitri

Hi
I donu2019t want to populate the list of the enumeration. The list is defined at design time. I just want to read key descriptions of the enumeration programmatically and I donu2019t want to use the context for that.
To your comment: if you use an input field with an enumerated data dictionary type, only the key of the enumeration will be shown in the field.
Regards
Dimitri

Webdypro simple types are vanished with model reimport

Hi All,
My webdynpro project consists of user defined simple types and models(SAP ABAP). when i re-import model ( which already exists in project ) , all the simple types in my project are deleted and all my context mapping to particular simple types are showing compile time errors. I have to recreate all simple types and do context mapping again.
Any one can help me how can i solve this problem.
Thanks
Aravinda

Before re-import the model you have to preserve existing model biding in controller contexts. There are two things you should take care about.
1. In controller contexts all metamodel entity files should be deleted.
2. non-model-specific files should be readonly.
There is one blog on this, which describes <a href="https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2508">How To Reimport Web Service Models in Web Dynpro for Java</a> , although it tell you about web services but it applies for model reimports as well.

Change Simple Type

Hi,
I have created a simple type and deployed. Now, when i am trying to edit,it is in read-only mode.How can i edit the description of simple type?
(Valuable answers will be awarded with points).
Thank you,
Arpitha

Hi Arpitha,
Well do you require to change the value at runtime or design time?
For designtime:
WebDynpro explorer->Dictionary->local dictionary-->Data types->simple type--->ur simple type(Name).
Double click ur simple type(name), automatically the window will open then change the fields and close.
or goto the WD Explorer and to the dictionary and open it you'll get the simpletype.Now here you can change it as per your requirement.
Please clarify if it's at runtime.
Regards
Amit

Unable to edit simple type

Hi ,
 I need to change the properties of the simple type that we have defined in the dictionary , We are using JDI .I have navigated to the dictionary --> rclick on the simple type --> selected EDIT --> Added the files to the activity --> now when i double click on the simple type and try to change the properties it is giving the following message :
 This simple type cannot be changed because the file xxx.xlf is read only .It is possible that the file has not been chacked out from DTR
 Any idea why i am getting this error .

Hi Maksim,
 When i do that it is allowing me to change the file , but when i try to save it i am getting the following error
cannot save language C:\Documents and Settings\test\.dtc\0\DCs\abb.com\report\Report_webDyn\_comp\src\packages\abb\com\report\web\dictionary\velement\LastTransIn.dtsimpletype.xlf
Please check the files e.g. for writeability / existence.

Read enumaration list of simple type

Hi,
I want to read enumaration list of simple type and compare it with user input. Simple type is not bound to any attribute.
How can I read enumeration list values?
Regards,
Apurva

Hi,
Thanks for replies.
I wanted to use simple type as storage space for Enumeration list. So, I can refer to this list and fill values from this list as required in the valueset.Not all values, based on some condition, some of the values in the list, will be added in the dropdown.
Now, if I cant refer to simple type without creating attribute, I will have to create redundant attribute just to access Enumeration list values.
Can I avoid it? Is there any better way of achieving this?
Regards,
Apurva

The type and the length of the members of the structures

I am making the BC-XAL program.
Reading `XAL_Interface_Documentation_11.pdf', now I succeeded in "Reading All Saved Monitor Sets" and "Reading All Monitors of a Monitor Set". but I can't find the type and the length of the member of the Structure BAPITNDEXT, so I cannot get the Monitoring Tree of a Monitor.
where can I get any documents or information ?

XI settings, change of Data Types and XI still maps old structures

Hi,
I have defined XI scenario, where synchronous WebService is being called, and XI calls RFC function module, which returns data. It was working perfectly, until
I have changed the order of few fields in Data Type and added a few new (exactly as the changes in RFC function module).
And now the WebService returns exception, on the first field added to the interface:
<Trace level="1" type="T">com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation: Cannot produce target element /ns1:MT_BMS_Response/CUSTOMERS_PERSON/TITLE. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at
TITLE is added field.
I have reactivated everything one by one again, clear cache from Integration Builder and Integration Directory, but it does not help and still old structures are being used in XI.
I have tested the Interface Mapping and all fields are transformed correctly.
Please help as it comes a little urgent and I have run out of ideas what to do to refresh the customizing of data types?
Thank you in advance!

Hi Peter,
Yes, I am calling RFC function module from XI.
After I changed the interface of RFC in SAP, I have imported this RFC once more to XI in Integration Builder and new structures appeared.
And exception returned is that first new field added to the RFC and Data Type and so on, returns an exception.
And returned XML structures (in message monitoring) appears to be still old structures.

Is there any way to bring back the font type and background of Safari reader from iOS6 in to the iOS7 ? I really miss it, the new design is awful, simple and has now class at all.

Is there any way to bring back the font type and background of Safari Reader from iOS6 in to the iOS7 ? I really miss it, the new design is awful, simple and has now class at all.

I agree with you, many things in the ios 6.x were more elegant. The reader was the most one of them. I think the ios7 wants to be the windows 8.

Reg. checkbox by group and simple types

Hi,
I have checkbox by group UI elemnet.
I have binded the text property of the checkbox by group to a context attribute and its type property is selected from a simple type.
In the view layout on NWDS its showing the label names which i hav given in the simple type. but when i deploy it and run it in browser its just showing only one check box. its not showing the label names.
how to get the label names, using simple types. i,m able to get it using code.
how to get it by simpletype???
thanks, suresh

hi,
in case of check boxes, it will not work with
a simple type
write code similar to this according to your requirement
in wdDoModifyVIew();
if(firstTime){
String[] names = {"one","two","three"};
for(int i=0;i<names.length;i++){
IPrivateCheckView.IXElement nelem =wdContext.nodeX().createXElement();
wdContext.nodeX().addElement(nelem);
nelem.setName(names);
where X is a node ,
Name is attribute under node X
of type string
bind the texts property of the check box group to the Node X

Satya.
