Dynamic types with CL_ABAP_TYPEDESCR

Hi,
I have a problem. I want to read out the output_length of dynamic types to evaluate inputs. I do something like the code below.
DATA type_ref TYPE REF TO cl_abap_typedescr.
DATA elem_descr TYPE REF TO cl_abap_elemdescr.
DATA struc_descr TYPE REF TO cl_abap_structdescr.
type_ref = cl_abap_typedescr=>describe_by_data( <fs_lsinto> ).
elem_descr ?= type_ref.
elem_descr->output_length
But sometimes type_ref give back a CL_ABAP_STRUCTDESCR and I get a dump at '?='.
How I can solve my Problem?
Sinan

How about something like this.
report zrich_0001.
data type_ref type ref to cl_abap_typedescr.
data elem_descr type ref to cl_abap_elemdescr.
data struc_descr type ref to cl_abap_structdescr.
data comp_tab type abap_compdescr_tab.
data comp_wa like line of comp_tab.
parameters: p_name(30) type c.
type_ref = cl_abap_typedescr=>describe_by_name( p_name ).
if type_ref->type_kind = 'u'.            " <- Structure
struc_descr ?= type_ref.
loop at struc_descr->components into comp_wa.
    catch system-exceptions move_cast_error = 1.
      data: tab_component type string.
     concatenate p_name comp_wa-name into comp_wa-name separated by '-'.
      elem_descr ?= cl_abap_typedescr=>describe_by_name( comp_wa-name ).
    endcatch.
    write:/ comp_wa-name, comp_wa-length, elem_descr->output_length.
endloop.
else.
elem_descr ?= type_ref.
write:/ p_name, elem_descr->output_length.
endif.

Xml conversion of data refs with dynamic type

Hi Colleagues,
I have to create an XML from a TYPE REF TO DATA, where this data is created using a dynamic internal table. By dynamic internal table i mean that the internal table is created dynamically using the class method cl_alv_table_create=>create_dynamic_table.
Now the problem that i face is when i use the statement:
CALL TRANSFORMATION id
      SOURCE jsag_data = im_context_b64
      RESULT XML lv_xml
      OPTIONS data_refs = 'embedded'
              value_handling = 'move'.
to generate the XML i get a dump of type CX_XSLT_SERIALIZATION_ERROR saying "The ABAP data cannot be serialized."
I found a solution to avoid the dump by adding the additional option " TECHNICAL_TYPES = 'ignore' " to the CALL TRANSFORMATION statement, like
CALL TRANSFORMATION id
      SOURCE jsag_data = im_context_b64
      RESULT XML lv_xml
      OPTIONS data_refs = 'embedded'
              value_handling = 'move'
              TECHNICAL_TYPES = 'ignore'.
But, using this addition the dynamic type ref to data part is totally ignored from the XML generation.
If I use a specific DDIC table type to create the data, we do not face this issue and the XML is generated as desired
Does anyone have a solution to this problem as it has become a sort of blockade for our development?
Thanks and Cheers,
Gaurav.

Hello,
I reached same problem with dynamic data references, the only solution I got is to used global DDIC types (also for table types !!) when creating data which needs to be serialized.
The options technical_types = 'ignore' doesn't solve the problem - it just instructs the parser to skip data references without global ddic type. The options value_handling = 'move' is very helpful as XML serialization is very picky about values beeing serialized.
Here is summary of my observations:
- Global DDIC type has to be associated with data reference, otherwise only technical type is there and this is not supported (you can use OPTIONS TECHNICAL_TYPES = u2018IGNOREu2019 but this will just skip the data to be serialized to XML) u2026
- The above means that if you are serializing data reference to table then you have to have also global DDIC type for the table-type !! Unfortunatelly there is no default table type available for transparent tables u2026. They are treated as structures not as table-types u2026 thus:
- CREATE DATA lr_data TYPE <global_ddic_structure> - can be serialized
- CREATE DATA lr_data TYPE STANDARD TABLE OF <global_ddic_structure> - cannot be serialized
- CREATE DATA lr_data TYPE <global_ddic_table_type> - can be serialized
- !! Unfortunatelly !! CREATE DATA lr_data TYPE <type_pool_ddic_structure/ type_pool_table_type> - also cannot be serialized u2013 this is pitty u2026 this should be supported u2026.

Not sure how to pass record type dynamically...

sb,

       DBMS_OUTPUT.PUT_LINE(V_SQL);
      end;when I execute this...l_shl_order_msg is passed as variable..but instead I want to pass all columns in the recordtype to be passed..
ex : l_shl_order_msg.id, l_shl_order_msg.name....etc..
This is what is being passed :
BEGIN ATTRIBUTE_PRC( l_shl_order_msg ,'CDS_1','text-1', CRAE_INTERFACE.GLB_VAR_PKG..V_TEXT );
ATTRIBUTE_PRC has already been defines as record type with i/p parameter..

Dynamic programming using cl_abap_typedescr

I have created a field catalog for an ALV grid dynamically using cl_alv_table_create=>create_dynamic_table (I am on 46B and cannot use the new version). How do I create the structure and therefore internal table to pass into the it_outtab parameter of the ALV grid set_table_for_first_display
method? I can create a blank table with the correct dynamic columns but now wish to populate it without much success! I am retrieving the type using cl_abap_typedescr=>describe_by_data and can cycle through the key but how do I just obtain the structure?
Cheers
Ian
cl_abap_typedescr to retrieve the column names of a dynamic table I have created for using with an ALV grid

Hi,
Use ASSIGN r_dyn_table->* TO <t_dyn_table> to get access to the dynamic table. To append rows to it, you should use ASSIGN COMPONENT idx/name OF STRUCTURE struc TO <fs>.
Example:
    data: tab_fields like table of wa_fields,
         r_dyn_table TYPE REF TO data,
         r_wa_dyn_table   TYPE REF TO data,
         f_int type i.
CALL METHOD cl_alv_table_create=>create_dynamic_table
      EXPORTING
        it_fieldcatalog           = F_TAB_FCAT
      IMPORTING
        ep_table                  = r_dyn_table
      EXCEPTIONS
        generate_subpool_dir_full = 1
        OTHERS                    = 2.
      ASSIGN r_dyn_table->* TO <t_dyn_table>.
      CREATE DATA r_wa_dyn_table LIKE LINE OF <t_dyn_table>.
      ASSIGN r_wa_dyn_table->* TO <wa_dyn_table>.
      DESCRIBE TABLE tab_fields lines f_int.
      do f_int times.
        READ TABLE tab_fields INDEX sy-index into wa_fields.
        ASSIGN wa_fields-field TO <w_field1>.
        check1 = sy-subrc.
        ASSIGN COMPONENT sy-index
               OF STRUCTURE <wa_dyn_table> TO <w_field2>.
        check2 = sy-subrc.
        if check1 = 0 and check2 = 0.
          <w_field2> = <w_field1>.
        endif.
      enddo.

Dynamic action with set value on date field

Hi,
I'm using APEX 4.02
I'm trying to calculate the age based on the date of birth dynamically on a form. I'm trying to do this with a (advanced)dynamic action with set value.
I'm able to get this kind of action working based on a number field etc, but NEVER on a date field.
I've read all posts on this subject but so far no solution. Even if I try to simply copy the value over to another date field or typecast it to a string ( to_char function ) it does not work. So for me the problem seems to be in the source field being a date field.
I've tried using the source value as is in a select statement :
select :P33_GEBOORTEDATUM from dual;
and also type casted based on the date format :
select TO_DATE(:P33_GEBOORTEDATUM,'DD-MON-YYYY') from dual
but still no luck.
On the same form I don't have any issues as long as the calculation is based on number fields, but as soon as I start using dates all goes wrong.
Any suggestions would be greatly appreciated. If you need any extra info just let me know.
Cheers
Bas
b.t.w My application default date format is DD-MON-YYYY, maybe this has something to do with the issue .... ?

Hi,
Create a dynamic action named "set age" with following values.
Event: Change
Selection Type: Item(s)
Item(s): P1_DATE_OF_BIRTH
Action: Set value
Fire on page load: TRUE
Set Type: PL/SQL Expression
PL/SQL Expression: ROUND( (SYSDATE - :P1_DATE_OF_BIRTH)/365.24,0)
Page items to submit: P1_DATE_OF_BIRTH
Selection Type: Item(s)
Item(s): P1_AGE

Dynamic type conflict during the assignment of references. - Error while generating proxy in the backend

Hi All,
I get a short dump while generating a proxy in the backend.I give the package and the prefix and end up with a short dump.
Does any one know why this mught come up
"Dynamic type conflict during the assignment of references."
background: I imported a WSDl provided by legacy into PI and created service interfaces and then trying to generate a proxy class while i get this error.
Thanks.

Hi Shyamsundar,
I will explain a problem that I usually see in some developments:
XSD originally:                                  XSD transformed:
Root                                                     -> Root
Tag 1 type int                                    -> Tag 1 type int
Tag2 type string                               -> Tag2 type string
Tag3 type any                                  - Tag3 type string
Normally the tag3 should have a XML inside. Then the ABAPers have to construct the tag3 with a CDATA structure (CDATA is used to put in an XML tag more XML tags inside like a text and no to be interpreted).
Later in SAP PI you can extract the cdata with an XSL, you can find some examples in the SCN.
I don’t like to convert the whole XML in only one string tag, because this makes difficult the develop for the ABAPers, although the work inside the PI is very easy because with an XSL you can extract the whole message easily. (You can find some examples in the SCN)
Regards.

How do you turn off larger dynamic type on the iphone4 when your screen orientation is locked (vertically)?

So I have the iphone 4 with the latests update ios7.
So I went on settings > general > accessibility > larger type.
And I clicked "on" for "larger dynamic type"
Now my font is so big I can't even see apps that I have and such
I want to turn it "off" but my screen orientation is locked! (I can't move my phone horizontally) I think if I can move my phone horizontally I'll be able to see the on/off button for larger dynamic type.
I tried sliding the bottom upwards to turn off screen lock orientation but it's not on my screen because my font is set to a really big size that the "screen orientation lock button" didn't make it to the screen

Turning on Dynamic type and increasing it shold not have that effect.
Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.

Dynamic table with dynamic drop-down list values

Hi,
I need to display a dynamic table with 2 columns on an interactive form.
My Context is defined as below:
Root
StudentData     0..n
StudentName
StudentCourses     0..n
Text
Value
The 1st column should display student name, 2nd column should display student courses. The courses will be different for each student. I populated the context properly. I checked it by printing them. My DDL is bound to "Student Courses".
When there is one row -> The DDL is populated with the courses of student 1 (as there is only one).
When there are more rows -> The DDLs for all the students are populated with all the courses of all the students.
I want to see the data populated like:
TEXTFIELD    DROP-DOWN LIST
Student 1------Student1-Course1
Student1-Course2
Student1-Course3
Student 2------Student2-Course1
Student2-Course2
Student2-Course3
I tried to do this in plain web dynpro using SVS.. it is also working similarly.
I have set the singleton property of nodes "StudentData" and "StudentCourses" to false.
Could any one tell me where I am going wrong?
Thanks
Ram

Ram,
I'm not sure how much this will help, but I know I had the same problem as you when I tried to get a similar thing working, but I can't remember which of the many changes I made fixed the problem, so I'll just show you my code and perhaps you can see if anything is different than yours.
Here's where I'm creating my dropdown - in my case EastNew_RegOut is the same as your StudentData, and RateTypeDropValues is the same as your StudentCourses (the comments in the code are not meant to sound bossy to you, this is actually an example piece of code that other developers in my company "steal", so I have to put very specific instructions in there!):
int nodeSize = wdContext.nodeEastNew_RegOut().size();
for (int i = 0; i < nodeSize; i++) {
     //create an element called "table", that's the element at i. So, basically it's a row. Maybe I should have
     //called it "row" instead of table.
     IPublicDeviceExchange.IEastNew_RegOutElement table = (IPublicDeviceExchange.IEastNew_RegOutElement)wdContext.nodeEastNew_RegOut().getElementAt(i);
     //this line of code just executes an rfc that finds out what rates need to be in the dropdown for this particular row
     executeRateTypeDropdown(rateCategory, table.getNum(), wdContext.currentEastNew_MeterOutElement().getReggrp());
     //clear out what's already in there before we re-populate it.
     table.nodeRateTypeDropValues().invalidate();
     //now, I'm looping through all the values in the *actual* rate type dropdown (the one that's an RFC, populated by the above "execute" method)
     for (int j = 0; j < wdContext.nodeEastRatetype_DropdownOut().size(); j++) {
          //for each element in the *actual* Rate type dropdown, I'm going to create an element in my node that I created
          //and set the values from the *actual* one as the values in my node.
                    IPublicDeviceExchange.IRateTypeDropValuesElement element = wdContext.createRateTypeDropValuesElement();
          IPublicDeviceExchange.IEastRatetype_DropdownOutElement rateTypeOut = (IPublicDeviceExchange.IEastRatetype_DropdownOutElement)wdContext.nodeEastRatetype_DropdownOut().getElementAt(j);
          element.setText(rateTypeOut.getText());
          element.setValue(rateTypeOut.getRatetype());
          //here's another key - notice how I don't say wdContext.nodeRateTypeDropValues() - it's the one that's
          //directly off that table I created earlier - the thing that's essentially a row in my newReg table.
          //So, what I'm doing here is adding that new element I created to the dropdown FOR THAT ROW!
          //(btw, if you're trying to duplicate this, and this method does not exist for your "table" object, it's
          //probably because you didn't listen to me above and you didn't create your node with the singleton property
          //set to false.)
          table.nodeRateTypeDropValues().addElement(element);
As for my layout... my table is bound to the EastNew_RegOut node, and the column with the dropdown is bound to RateTypeDropValues.Value (that's probably obvious, but there you have it anyway)
Finally, in my context, EastNew_RegOut is singleton = true (I was surprised about this, actually, I would have assumed it was false) with a selection of 0..1 and RateTypeDropValues has singleton set to false with a selection of 0..1
I hope that helps to some degree!

Try with XQuery string-join() function :

Dynamic Type casting

Can we dynamically type-cast an object reference passed to Object Clss to that specific class?
Here is what I want to do.
I am going to pass an object reference to a method, which has Object class as parameter to it, as shown below. Using getClass() or some other way, I want to dynamically typecast this reference to the original Class and call some method of this Class.
void test (Object ref1){
((ref1.getClass())ref1).writeLog();
By doing this, am I violating the basic Object Orineted rules?

I mean, consider an hypothetical case (which is wrong
from OO point of view) that there are suppose 10
classes in my system. None of them related to each
other, all are independent classes. But each one has a
method called, writeLog(). Now I want to write one
method which will be called by each of these classes
(in some 11th class), which will have "Object" as a
parameter. Now using the actual reference I want to
call the corresponding writeLog() method.
1 - Point out to management that the design is now officially broken.
2 - Point out that if the design is not fixed then any solution that impliments the changes will cost more to maintain in the future and will likely lead to instabilities in the system (due to complexity.)
3 - Implement one of the suggested solutions and make sure that you put in a lot of error checking and logging in the hacked solution.
4 - Produce extensive documentation about the impact of changing any of the objects that you are relying on. Push it to anyone and everyone that might ever touch or even suggest changes to the code.
Doing all of the above allows you to live stress free when the next revision breaks because someone didn't understand the implications of your hacked solution. You will be able to find the problem quickly and point out that it had nothing to do with your code but rather because someone else did not follow the complete documentation that you produced. And then when they complain that your solution was a hack you can point out that you explained that previously as well.

Dynamic sql with dynamic bulk collection variable

Hi,
I am facing the issue while bulk collecting dynamic sql query data into dynamic variable.
Eg:
query1:= << dynamic select query>>
Execute immediate query1 bulk collect into Dynamic_varibale;
here dynamic_varible is pl/sql table type with 1 column.
How do i declare "dynamic_variable" here????
please suggest...

Dynamic table with radio buttons

I need to load a dynamic table with radio buttons that allow
the user to select an item in the table. I need to have it add a
radio button with a unique identifier for each table item.
For example: the table will load all of the seminars
locations available in a certain state, the radio button will allow
the user to select the city in which they would like to attend and
that value will get passed to the registration page. The value of
each radio button would be equal to the location_id in the database
for each of the locations in the table (The table includes the
date, day, venue, address, hotel info, etc. details for each city.)
When I add dynamic radio buttons and set the value to the
location_id in the database, it allows the user to select multiple
radio buttons. I cannot find any information on how to
resolve.....??
Any help is appreciated.

Give each radio button the same name
<input type="radio" name=theLocation" value="<?php
$recordset['location_id'] ?>">

Dynamic Table with references

Hello everybody,
im tried to create a dynamic table with cl_alv_table_create=>create_dynamic_table, but that doesnt work for the table i need. I need a table with a changing number of columns of type "type ref to CL_DD_INPUT_ELEMENT", but the fieldcat only takes normal Data-Types.
So my question is, is there any way to create a dynamic table or structure with components of type ref to CL_DD_INPUT_ELEMENT?
Thank you very much for any help.
Cheers

I generally use Factory methods of RTTS classes to create dynamic tables. Check my reply (Step 1) in this thread getting column headers dynamically from input parameters in alv..

Dynamic type variable creation

I want to create a variable with a pre-defined TYPE, but the latter will only be known at runtime.
For instance:
Consider that I my DEFINITIONS1 include file is:
TYPES: BEGIN OF type1,
                field1 TYPE i,
                field2 TYPE i,
                field3 TYPE i,
            END OF type1,
              BEGIN OF cust_type_A,
                   INCLUDE TYPE type1.
TYPES:       erdat TYPE vbak-erdat,
              END OF cust_type_A,
             BEGIN OF cust_type_B,
                   INCLUDE TYPE type1.
TYPES:       fkdat TYPE vbrk-fkdat,
              END OF cust_type_B.
Than I have the following code (assume "letter" is a character parameter I receive, either 'A' or 'B'):
INCLUDE definitions1.
DATA: z TYPE REF to data.
FIELD-SYMBOLS: <fs> TYPE ANY.
DATA str type string.
CONCATENATE 'MY_CUST_TYPE_' letter INTO str.
CREATE DATA z TYPE (str).
* ASSIGN z->* TO <fs>.
Why is that that the CREATE DATA z TYPE (str) statement fails ?
How, then, I create a variable/field symbol from a specific type, which will only be known at runtime ?
Thanks
