How to create dynamic types?

Hi gurus!
I want to refer on a strucutre, whose components' definitions are available only during runtime.
Example:
The type which i want to refer on should be a structure with one component, which is a CHAR with variable length. (i.e. the VALUE of the component's parameter LENGTH is evaluated during runtime).
Any hints are welcome.
With best regards Jonas

use cl_abap_elemdescr=>get_c( length )
DATA: r_stru TYPE REF TO cl_abap_structdescr,
      it_comp TYPE cl_abap_structdescr=>component_table,
      r_comp TYPE abap_componentdescr,
      r_elem TYPE REF TO cl_abap_elemdescr,
      r_data TYPE REF TO data.
DATA: length_of_field TYPE i VALUE 10.
FIELD-SYMBOLS: <fs> TYPE ANY.
START-OF-SELECTION.
r_elem = cl_abap_elemdescr=>get_c( length_of_field ).
r_comp-name = 'FIELD1'.
r_comp-type = r_elem.
append r_comp to it_comp.
r_stru = cl_abap_structdescr=>create( it_comp ).
CREATE DATA r_data TYPE HANDLE r_stru.
ASSIGN r_data->('FIELD1') TO <fs>.
<fs> = 'ABC'.
WRITE: / <fs>.

How to create dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."
How to create dynamic context based on a structure defined in the program?
I have written the code like this:
TYPES: BEGIN OF t_type,
            v_carrid TYPE sflight-carrid,
            v_connid TYPE sflight-connid,

         wa_struc type t_type.
data: dyn_node   type ref to if_wd_context_node.
data: rootnode_info   type ref to if_wd_context_node_info.
rootnode_info = wd_context->get_node_info( ).
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.

How to create dynamic strcture and accepting runtime value in work area

Hi,
I am using RFC_READ_TABLE for joining more than table and written select query but into clause work area value is passed but it is short dump is displaying with too few many fields in into clause .work area WA need some casting type conversion which accepts the some run time value and should have some structure for it.how to create dynamic structure?

hi
good
go through this and use in your report accordingly.
If you are trying to read some information from SAP and you can't find the right BAPI then RFC_READ_TABLE can do the job for you.
RFC_READ_TABLE is powerful RFC it gives you the access to all tables and views in SAP. I basically used RFC_READ_TABLE for Material Master Search application on the Intranet.
Now you may say there are lots of BAPI for this functionality. You are right but I had to work around the BAPI to get Prices (Moving Average Price) and it just did not work very well. Because of the nature of the application I had to use RFC_READ_TABLE because then I can use powerful SQL expression for searching. RFC_READ_TABLE give you the ability to code the where clause which is quite enough.
I have included part of the code use in asp page to read ENT1027 for Mgroup and M description & number but without object creation. The other part of the code reads MBEW for price & quantity.
Code

How to create dynamic nested internal table

Hi Experts,
Pleae tell me or give sample code, how to create dynamic nested internal table ?
I have seen threads saying creation of dynamic internal tables using some table structure only. But now the requirement is to create dynamic nested internal table.
For example the internal table contains two fields viz., one is field1 of dynamic internal table and other is normal field2 and values as shown below:
Nested internal table:
field1                     |     field2 ...
<table content1>     |     value2..
<table content1>     |     value2..
Here the [table content] should also a dynamic internal table.
Let me know if you need any other info.

or
Vector1,Vector2,Vector3 .....n, the n value i will get at run time, so how to create the dynamic ArrayList or Vector or i can use any other Object in java,
Pls provide your input.
Sridhar

1. I have a HashMap with dataok ... fair enough.
2. depending on its size, i need to create variable
to store them.uhm ... why? If you have a variable number of elements in the map then you'd need to generate a variable number of variables (a number, that is not know at compile time, as it seems). Now if you could somehow create those variables, how would you access them? You'd have to generate the code handling them as well ...
Tell us what kind of data you've got and what you want to do with it. There's certainly a better solution to your problem.

Neelmani,
How: write some code.
The Web User Interface Developer's Guide for Oracle Application Development Framework will be helpful. Hint: you may want to read section 14.2 (especially 14.2.1, item 2, which talks about using iterators in a menu) OR section 17.5, which talks about creating menus to support page hierarchies.

How To create Dynamic destination in blazeDS

Hi,
Can anyone tell me how to create dynamic destinations ?
thnks

hi,
Basically you could read the destination and Endpoint from an xmlfile then feed the values as required, the following is a simple hardcoded setup but it doesn't take much to set vars in the creationcomplete event. At least this way you don't need baked in settings.
<fx:Declarations>
<s:Producer id="myProducer" destination="{myService}" acknowledge="myProducer_acknowledgeHandler(event)"/>
<s:Consumer id="myConsumer" destination="{myService}" message="messageHandler(event)"/>
</fx:Declarations>
private var channelSet:ChannelSet;
private var myService:String;
protected function application1_creationCompleteHandler(event:FlexEvent):void
channelSet = new ChannelSet();
myService = "chat";
//var channel:AMFChannel = new AMFChannel("my-polling-amf","http://localhost:8080/blazeds/messagebroker/amfpolling");
var channel:AMFChannel = new AMFChannel("my-polling-amf","http://ezflex.net:8080/blazeds/messagebroker/amfpolling");
channelSet.addChannel(channel);
myProducer.channelSet=channelSet;
