Hello Experts.
how to create dynamic data type for structres. for example.
data lv_struc_name type strukname.
lv_struc_name = get_struct_name( ) ****** this method gives the structure name('ct_struc')
now I want to create one data type, which is having the type of lv_struc_name content.(ct_struct)

How create data type for coulmn name having special characters in IR

any idea how to create how to do create data type for coulmn name having special characters

Hi Amit,
Can you ellaborate ?
Actually if you are reading a file(or anything else) which contains special characters, the data type can be created as done for other interfaces. But it is in the adapters that we actually take care of handling these special characters.

First activate your namespace and then create the data type.
Namespace + default datatypes should be activated together.

Create dynamic data type in structure

Hi Experts,
I am new to ABAP.
In my scenario data type is varying for the field. for that I need to create dynamic data type in structure, this structure I am using for internal table for OVS search input.
Please suggest the solution for this.
Advance thanks,
Regards,
BBC

Thanks for your quick reply,
I used your logic like this.
data:
ls_component type abap_componentdescr,
lt_component type abap_component_tab.
*... (1) define structure components :
clear ls_component.
ls_component-name = 'NVALUE'.
ls_component-type ?= cl_abap_typedescr=>describe_by_name( <fs_seg_v>-fieldname ).
insert ls_component into table lt_component.
*... (2) create structure
data lr_strucdescr type ref to cl_abap_structdescr.
data lr_data_struc type ref to data.
lr_strucdescr = cl_abap_structdescr=>create( lt_component ).
create data lr_data_struc type handle lr_strucdescr.
field-symbols <fs> TYPE any.
assign lr_data_struc->* to <fs>.
your logic is working fine.
here I am getting feild name (<fs_seg_v>-fieldname) from internal table.
But I need to assign same field name structure to query parameter.
FIELD-SYMBOLS: <ls_query_params> TYPE lty_stru_input.
Please can you suggest how I can refer the field name structure?

Why need message type when u create data type...

why need message type when u create data type...

Hi,
A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:
·        More than one message interface can use the same message type. For example, an asynchronous outbound message interface and an asynchronous inbound message interface can reference the same message type because the request message does not need to be mapped.
·        When defining a message mapping you can directly reference message types to map messages from an outbound interface to messages from a receiver interface.
For technical reasons, a data type is not sufficient to describe the instance of a message. In XML schema, data types are defined as abstract types that are not yet fixed to an element. You can only describe an instance of a message when you have specified a data type as an element type. Therefore, a message type defines the root element of a message.
A message type does not define the direction of the message exchange, in other words, whether it is a request or a response. In exceptional cases you can use the same message type for both the request and the response message.
A message type has the following characteristics:
·        It comprises exactly one data type, which determines the content of the message to be transferred.
·        It is identified by a name and an XML namespace. The name (together with the namespace) of a message type is located in the uppermost tag of the message to be exchanged. This is an element tag.
You have defined a message type GreetingRes that references a simple data type of type xsd:string. The XML namespace of the message type is http://sap.com/xi/myExample. The corresponding payload might look like this:
<?xml version="1.0" encoding="utf-8" ?>
<ns1:GreetingRes xmlns:ns1="http://sap.com/xi/myExample"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   Hello Mrs. Miller
</ns1:GreetingRes>
You can specify how a message type is used in more detail in the description
hope this will help you.

Creating data types

Hi
How do u create a data type when u get an input file.
How do u know when to create header , footer n all?
Can some one tell me or send a url on how to create data types. would be of great help!
Thanks!

HI,
Generally identifying the structure from the input file need some analysis work.
You may refer some of the below tips while creating the data types
1. List down the input structure of data fields from input file.
2. Decide the Header and detail information based on the data and go for sub-structure.
3. With File adapter try to maintain the structure level max. upto 2.
i.e. Root>Header>Fields etc.
4. Try to avoid the substructure for the internal fields.
5. Decide the Occurances fo every root and sub structures and fields.
6. Identify if there any relations within Header and detail fields.etc.
Check with SAP Help for various activities

Import XSD to create Data type in Design

hi,
I know that we can import XSD in Design and create data type,my question is:
1. Can i import an XSD thats been created in message mapping and use that to create my data type in design.
(or)
2.Should i have to write an XSD on my own and then import it to create my data type, and is there any standard format to write it.

Hello Prashanth,
For your first question: i don't know exactly what you mean that the the xsd you create in the data mapping steps. So can you explain it in details?
For your 2nd question: Sure you can write your own XSD to create a data type. And i will give you an example xsd file format. Then you can import it in the XSD tab view.

Problem in creating data type

hi..
i've problem in creating data type in xi after importing idoc from the R/3 sender
plz tell me the basic steps for creating data type in the receiver i.e xi.....
thanks in advance

Hi,
You don't need to create a data type after importing the IDOC.
Idoc itself acts as message type and message interface.
check this for creating a data type..

Labview How to specify 1d array of clusters as data types for variant to data

Hi, I'm new to labview. Can anyone tell me how to specify 1d array of clusters as data types for variant to data?

First of all, you should be sure that there is such a data type within the variant; otherwise, you will run into errors.
I recommend you to create the cluster and create a type definition from it. Then drop an array shell from the array palette and drop the cluster type into that array.
Connect that constant to the data type input of the Variant To Data function.

Validation while create data type

HI All ,
I have a pop-up in my report that user can create data type in didc,
There is a simple way to support validation for data types ,
I have pop-up where the user need to provide name of attribute
he need to create and the data type for it (char ,string ,int etc )
and he also need to provide the leng of the attribute he want to create
(e.g. char10 ) and also decimal places .
the issue here that i need to do some validation in the pop-up
for e.g. if user choose
case 1
name     - attribute1
datatype - string
leng   - in this case he dont need to provide leng (string )
dec - dont need to provide (string )
case 2
name     - attribute1
datatype - char
leng   - 10
dec - dont need to provide (char )
Any idea how to do this validation in a simple way (maybe to use standard functionlity)
Regards
Alex

HI Keshav.
What i did is created a popup with FM in the popup i have 4 field
the field with the data type which i want to trigger event to it is domain and not ref to FM
The ppoup have 4 field
attr name
datatype
length
decimal
so from what you are say there is not option to trigger event when the user press F4
and choose a entry from it ,
since what i want to do is that if user for instance chose string i want that the next to fields (length and dec ) will be
remove from the popup since he dont need them .
and for he choose char the the decimal field will remove from the popup
Any idea how to solve this issue ?
Regards
Alex
