Dynamic table from an structure

Hi,
I want to create one alv grid using function REUSE_ALV_GRID_DISPLAY,for this i have passing the fieldcatalog to slis_t_fieldcat_alv.i have been passing my fieldnames ,and col,sel_text_m to fieldcatalog.instead of passing the fields can we assign fields catalog dynamically from the structure.....i have all the fieldnames in one structure for to be displayed in alv list.
pls read the below for reference....
DATA : BEGIN OF wa_inv,
       lifnr LIKE rbkp-lifnr,
       belnr LIKE rbkp-belnr,
       bldat LIKE rbkp-bldat,
       END OF wa_inv.
fieldcatalog-fieldname = 'LIFNR'.
fieldcatalog-seltext_m = 'Vendor'.
fieldcatalog-col_pos = 0.
fieldcatalog-outputlen = 10.
fieldcatalog-sp_group = 'X'.
append fieldcatalog to fieldcatalog.
clear fieldcatalog.
*.....this following part will be avaid ..and it should *..be assigned to dynamically
fieldcatalog-fieldname = 'BELNR'.
fieldcatalog-col_pos = 1.
fieldcatalog-seltext_m = 'Invoice No'.
fieldcatalog-key = 'X'.
append fieldcatalog to fieldcatalog.
clear fieldcatalog.
fieldcatalog-fieldname = 'BLDAT'.
fieldcatalog-seltext_m = 'Invoice Date'.
fieldcatalog-col_pos = 2.
append fieldcatalog to fieldcatalog.
clear fieldcatalog.

Hi ,
here's an example for fm REUSE_ALV_FIELDCATALOG_MERGE
-> fields of itab must be defined with like not with type!
DATA : BEGIN OF itab1,
f1 LIKE vbak-vbeln,
f2 LIKE vbap-posnr,
f3 LIKE vbak-netwr,
END OF itab1.
rep = sy-repid.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
i_program_name = rep
i_internal_tabname = 'ITAB1'
i_client_never_display = 'X'
i_inclname = rep
CHANGING
ct_fieldcat = fcat.

Defining table from DDIC-structure dynamically

Hi folks!
Does anybody know whether it is possible to build an internal table from DDIC-structures dynamically?
I have a deep structured itab_upload(whose structure is defined in the DDIC), which contains 2 fields(Number Name) and a third field which contains itab_desc.
This itab_desc can contain either 2 fields(Number Name) and a third field which contains another itab_desc <b>or</b> 3 fields for numbers(without any other itab).If itab_desc contains another itab_desc, the second itab_desc contains only 3 fields for numbers and names...
help will be very appreciated and points will be rewarded!

EA3, Unhooking a table from a structured type

When I reset the drop down 'Based on Structured Type:' on the 'Table Properties' window for a relational model, the attributes that were inherited from the underlying structure which are displayed as columns in the table are not removed. I'm not sure if that is by design or by accident. I would prefer that if the table is unhooked from the object type that the object attributes would be removed from the table.
This is in Data Modeler EA3 3.1.0.691
Thanks,
ScottK
Edited by: ScottK on Jan 17, 2012 1:10 PM

In SDDM 3.3 EA2 if I unhook an object table from the structured type the columns remain. I can then replace one of those columns as the primary column, replacing the object table generated column value Oid. If I rehook (based on structured type) that table back to an object type, I am not able to use any of those inherited attributes as a column value within the primary key structure.
In a normal object table definition or an object relation table the structured type's attributes can be used as a primary key column. The problem only surfaces if I accidentally un-define the setting on (based on structured type) and then try to reset it.

HR Logical database PNP. OO to fill table dynamic table from PNP ?

Hi all
I want to get some stuff from the HR logical database into a dynamic table
Here's a real simple example that writes info out to a normal list.
(report is based on using Logical DB PNP)
tables: pernr.
INFOTYPES: 0001,                     "Organizational Assignment
           0002.                     "Personal Data
SELECT-OPTIONS: language FOR p0002-sprsl.
INITIALIZATION.
pnptimed = 'D'.
GET pernr.
PROVIDE * FROM p0002 BETWEEN pn-begda AND pn-endda.
    CHECK language.
    WRITE: / p0002-pernr,
             sy-vline,
             p0001-ename,
             sy-vline,
             p0002-sprsl,
             sy-vline,
             p0002-gbdat.
ENDPROVIDE.
endform.
Now what I want to do is replace the write stuff by appending the entries into a dynamic table which I will display as an ALV Grid.
so I add my structure in the data declarations
types: begin of s_elements,
   pernr type p0002-pernr,
   ename type p0001-ename,
   sprsl type p0002-sprsl,
   gbdat   type p0002-gbdat.
drop_down_handle type int4.
types: end of    s_elements.
include zz_jimbo_incl.
build the dynamic table
create data dref type s_elements.
assign dref->* to <fs>.
i_routine = 'POPULATE_DYNAMIC_ITAB'.*
i_names   = 'NAME_COLUMNS'.
i_gridtitle = 'HR TEST'.
invoker = sy-repid.
i_zebra = 'X '.
i_edit = ' '.
call function 'ZZ_CALL_SCREEN'
     exporting
          invoker     = invoker
          my_line     = <fs>
          i_gridtitle = i_gridtitle
          i_edit      = i_edit
          i_zebra     = i_zebra
          i_names     = i_names
          i_routine   = i_routine
     importing
          z_object    = z_object
          dy_table    = dy_table.
Now to populate the dynamic Itab the routine below is entered.
form populate_dynamic_itab changing dy_table.
assign dy_table->* to <dyn_table>.
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.
However I can't use GET / PROVIDE / ENDPROVIDE in a Form.
Anyway round this ---seems HR has an aversion to OO.
Cheers
jimbo

Hi,
well, GET_PERNR is a so called event_statement. It has nothing to do with ABAP 00.
Normally it will be like this:
START-OF-SELECTION.
GET_PERNR.
PROVIDE ....
END-OF-SELECTION.
-> and here the CALL SCREEN NNNN for ALV-Display.
Provide-statements you can use in forms of course, and as many times you want during GET and END-OF-SELECTION.
But as I understood : you just want to save the write-statements?
I always develop a DDIC-Structure, declarate the data objects in the programm, read the data via Provide into the infotypes, and then make a move-corresponding to my structure. and display it.
Normally no problem.
kind regards
maik

Dynamic table from POJO

Hi,
can someone tell me, how I create a table from a POJO. The table must grow dynamically.
My problem is, that I didn't find a way to insert an array or a list to my report.
Thanks for your help.
Best regards
Christian

I think, that I solved the problem. But now I have a new problem: I give Crystal Reports a Collection with 3 objects, and I want to display the object in the body. One attribute of the POJO is a name. I want, that CR display them in a list, the second after the first and so on. But CR genartes a PDF with 3 pages, every name has his own page.
Has someone an idea what I make wrong? Thanks for your help!!
Best regards
Christian

Generating Dynamic UI from XML structure

Hi All,
I have a requirement in which I need to select an entry in the first view and based on this, the second view would come come. But there are 30 different values that can be selected and each of them will have a different set of UI elements in the second screen. So if I go for normal static UI creation, then I need to create 30 odd views which is something we do not want.
The second option is to dynamically generate the UI elements in wdDoModify() method. But for 30 different conditions to check all the time will lead to performance issue.
So we are thinking if there is a way for webdynpro to dynamically read an XML structure that defines attributes and generates a layout for us dynamically.
Please provide your inputs on this. Also kindly suggest any other better ways for the solution.
Thanks and Regards,
Sayan Ghosh

Hello!
I think you should go with second one. But I don't know any "ready to use" solutions, so you have to
- Create your own XML structure, something like
<section type="yourCondition">
<input name="somePropertyName" type="text"/>

</section>
- Parse this XML into Java Model (on application startup for example)
- On user selection choose requred UI Model from memory and pass it to view
- In wdDoModify() build UI(elements, context attributes, mappings etc.) according to this model
It will be rather complicated for huge UI, but possible.
Thanks, Mikhail

NEED HELP... Creating dynamic table from data file...

Hi
I'm writing an application for data visualization. The user can press the "open file" button and a FileChooser window will come up where the user can select any data file. I would like to take that data file and display it as a table with rows and columns. The user needs to be able to select the coliumns to create a graph. I have tried many ways to create a table, but nothing seems to work! Can anyone help me?! I just want to read from the data file and create a spreadsheet type table... I won't know how many rows and columns I'll need in advance, so the table needs to be dynamic!
If you have ANY tips, I'd REALLY appreciated.....

Thank you for your help. I tried to use some of the code in the examples... I'm really new at this, so I'm not sure how to set it up. I added the code, but when I open a file, nothing happens. Here's the code I have so far...

Here's how to use DYNAMIC tables for almost any structure (4.6C onwards)

Hi guys
I'm describing a feature here that has been around since 4.6C that is not really well known but can really simplfy programming where you need to get data into some sort of internal table and then display it either as a classical list or as al ALV grid.
This feature is RTTI which allows you to retrieve your structure, build a dynamic FCAT (Field catalog) and a Dynamic table.
Here's a really quick little program which reads 200 entries from VAPMA into a dynamic table. Any structure will work if you use the code sample shown.
To pass it to an ALV GRID is then really simple as you've already got the Field Catalog, Table and Data.
The method I'm showing below will work for almost ANY structure you care to name whether or not the fields are in the data dictionary.
I create a dynamic FCAT and dynamic table based on the FCAT and then populate it.
You can create field catalogs dynamically quite simply by using the new RTTI facility available from 4.6C onwards.
(From here it's only a small step to dynamic tables and EASY ALV grid displays)
Example to create dynamic FCAT and table and populate it with 200 entries from VAPMA
PROGRAM ZZ_BUILD_FLDCATALOG.
tables: vapma.
Define any structure
types: begin of s_elements,
vbeln type vapma-vbeln,
posnr type vapma-posnr,
matnr type vapma-matnr,
kunnr type vapma-kunnr,
werks type vapma-werks,
vkorg type vapma-vkorg,
vkbur type vapma-vkbur,
status type c,
end of s_elements.
end of your structure
data lr_rtti_struc type ref to cl_abap_structdescr .
data:
zog like line of lr_rtti_struc->components .
data:
zogt like table of zog,
wa_it_fldcat type lvc_s_fcat,
it_fldcat type lvc_t_fcat ,
dy_line type ref to data,
dy_table type ref to data.
data: dref type ref to data.
field-symbols: <fs> type any,
<dyn_table> type standard table,
<dyn_wa>.
*now I want to build a field catalog
*First get your data structure into a field symbol
create data dref type s_elements.
assign dref->* to <fs>.
lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <fs> ).
zogt[] = lr_rtti_struc->components.
Now build the field catalog. zogt has the structure in it from RTTI.
loop at zogt into zog.
clear wa_it_fldcat.
wa_it_fldcat-fieldname = zog-name .
wa_it_fldcat-datatype = zog-type_kind.
wa_it_fldcat-inttype = zog-type_kind.
wa_it_fldcat-intlen = zog-length.
wa_it_fldcat-decimals = zog-decimals.
wa_it_fldcat-coltext = zog-name.
wa_it_fldcat-lowercase = 'X'.
append wa_it_fldcat to it_fldcat .
endloop.
Let's create a dynamic table and populate it
call method cl_alv_table_create=>create_dynamic_table
exporting
it_fieldcatalog = it_fldcat
importing
ep_table = dy_table.
assign dy_table->* to <dyn_table>.
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.
select vbeln posnr matnr kunnr werks vkorg vkbur
up to 200 rows
from vapma
into corresponding fields of table <dyn_table>.
from here you can pass your table to a GRID for display etc etc.
Cheers
Jimbo

Thanks for the info.
I went to their web site and also Googled.
I found a great review on their photographer's books on nikonians.org
They use an HP/Indigo Ultrastream 3000 digital offset press for all hardcover books, which is GREAT!
I did sign up and requested the 45 day trial "photographer" account.
I am curious if Shared Ink offers a size that matches the ONLY current book size from Aperture, the odd 8.5x11.
In the above review, I saw that Shared Ink offers a 12x12 book.. very nice! Except you will need to design that one in CS2
So then, all that Apple really needs to do is simply add the ability to select/create custom book sizes. Then we don't need a printing service from Apple, as there are plenty of options out there, and more arriving on the market each month!

Structure of Dynamic Table in Function Module

Hi,
I'm trying to find a way to get as OUTPUT a dynamic Table from a Function Module.
I declared a table called T_DATA without a type.
And this table should have a dynamic table back.
The problem that I get the data back but, I only found a data without any field-elements.
The data is there but there's no structure, no table.
Is there any way that I can send the Data in a proper structure?

Dynamic table pulled from SQL database, Need to Search

My table results are not static, they are pulled into a
dynamic table from a SQL database. Each table displays 10 records
with an option at the bottom to display additional records
(next/previous), for my query. I also have an option set up to
allow users to click for a detail view of a record in the table. If
the table data was static, I would be able to set up a search
option and a results page for it, but I'm dealing with dynamic data
on an .ASP page. I'd like to set up a search box to limit the
records displayed in the table. I haven't found any code samples
that are designed for dynamic data.
Here is a copy of the code from my table.

Hi,
I think the code on this URL will get you the solution

Livecycle userform with dynamic table

Hi Everyone,
New to Livecycle Designer and was hoping this is possible - Can you have a PDF userform with a dynamic table below it?...
Basically the user fills out a userform then clicks an ADD button - this populates a dynamic table below the userform then clears/resets the userform - as the records fill the table an EDIT button appears in the last column so that if the user makes an error with a record they could click the EDIT button, this would bring the record back into the userform fields so they could change the field(s) they made the error in then a SAVE button would replace the ADD button in this instance, clicking SAVE then changes the record and clears/resets the userform ready for more entries.
At the bottom of the PDF there would be an EXPORT button which attaches the table as a csv or tab-delimited text file to an email message...
If someone could point me in the right direction it would be appreciated - I have googled and searched the forums for an answer but they mostly relate to importing data into a dynamic table from a database or xml file... I was hoping to directly populate the table with the userform.
I also have a PDF example which illustrates what I am trying to achieve... but seems you cannot attach to a post... I can email it if someone has a solution, but needs to see it visually.
Cheers

You don't know the names of your columns? hmm you do, because before you created dynamic table you had to create field catalog, so the structure and column names of newly (dynamically) created table will be the same like defined in the field catalog.
The last loop also does not look good, in my opinion should be something like:
LOOP AT lt_datatable +(my first table)+ ASSIGNING <ls_data4>.
    AT NEW pernr.
      APPEND initial line to <fs_1> assigning <fs_2>.
      <fs_2>-pernr = <ls_data4>-pernr.
    ENDAT.
    ASSIGN COMPONENT <ls_data4>-wage_type OF STRUCTURE <fs_2> TO <fs_5>.
    <fs_5> = <ls_data4>-amount.
ENDLOOP.
also keep in mind that number of calls of method cl_alv_table_create=>create_dynamic_table is limited to 36 (?) calls within one program session because it uses dynamic subroutine pool behind so you will have short dump if you will execute that 37 times.

Exporting table from methode

Hi experts,
how can I handle it to exporting a table from a structure from a methode?
At the moment I export the structure in the methode but I need to export a table.
At the moment:
Parameter    Type           Typing Methode Associated Type
param_1      Exporting    Type                    structure
I need something like that:
Parameter    Type           Typing Methode Associated Type
param_1      Exporting    Type Table of      structure
... but that is not possible

I think he meant something like this
CLASS lcl_test DEFINITION.
PUBLIC SECTION.
    CLASS-METHODS: get_tab EXPORTING gen_table TYPE table.
ENDCLASS.
CLASS lcl_test IMPLEMENTATION.
METHOD get_tab.
    SELECT * FROM sflight INTO TABLE gen_table UP TO 10 ROWS.
ENDMETHOD.
ENDCLASS.
START-OF-SELECTION.
DATA: it_sflight TYPE TABLE OF sflight.
lcl_test=>get_tab( IMPORTING gen_table = it_sflight ).
"here IT_SFLIGHT holds what you want
Of course you could make it more generic, meaning query dynamic DB table inside get_tab and create dynamic table outside the method call to get returned data to that table. But basically it shows the idea.

How to assign values to dynamic table

Hi All,
I am working with a dynamic table and an internal table. My internal table looks like this.
Projno       Cust      Opt         Status
g1234       kkkkk       p1            I001
g1234       kkkkk       p2            I004
g1234       kkkkk       p3            I001
g1234       kkkkk       p5            I002
g1256       lmnvw       p1            I003
g1256       lmnvw       p3            I004
g1256       lmnvw       p5            I005
g1256       lmnvw       p7            I001
My Dynamic table struture looks like this
Projno Cust     p1 p2 p3 p4 p5 p6 p7
I need data in my dynamic table from my internal table as follows
Projno        Cust        p1    p2    p3     p4    p5     p6    p7
g1234       kkkkk       I001 I004 I001         I002
g1256       lmnvw       I003         I004         I005           I001.
The problem is these operations may vary thats why i am using dynamic table. Even i cannot use case statement as the operations may vary.
Is it possible to do using Assign component or some other way.
Thanks

Questions on: 1) Last Update; 2) Max String Length; 3) dynamic table keys

Hi:
- I am currently prototyping a plug-in but I have some questions:
- 1) At the 'All Metrics' table, what is the intent of the 'Last Upload' field,
and how is this field updated?
- I have created some metrics but for some metrics the 'Last Upload' field
has a timestamp but for other metrics there is no data.
As far as I know, the metrics are similar but I do not know why the behaviour is different.
- 2) Is there a maximum string length that the Oracle agent can accept?
- I have a script which just returns all the environment variables into one cell.
In emagent.trc, the Oracle agent issues the following warning:
2009-08-27 12:38:47 Thread-76336 WARN upload: Truncating value of "STRING_VALUE" from "AGENT_HOME=
- Is the truncation an issue?
- 3) I have created some dynamic tables from performing an snmp walk, but the key that I use
is the index of the SNMP table. The data is collected correctly, but I am not sure that using
the table index as the key for OEM is a good idea because the metrics are stored according to the SNMP table index.
Should the OEM key be the something like 'object name' instead of the index number from performing an SNMP walk ?
For example, when I click a metric, the metric name is: Sensor Index 1.
But should it not be something like 'Fan #1' ?
Thanks John

Metrics are collected at certain intervals, the Last Upload field indicates the date and time of the last time a metric collection was uploaded. The quicker the interval, the more recent that date should be. If you don't specify a CollectionItem in your default collection file for your metrics, they won't be collected or uploaded.
If your metric column is a STRING type, it is stored in a VARCHAR2(4000)
I'm not sure I understand your last problem... You have a table metric with a set of columns. The column you use as the key is just some tracking index which doesn't really mean anything. As long as your key column(s) make the row unique, the agent will be satisfied. If you want something more meaningful as your key, then it's something you will have to inject into your dataset if it isn't already there.
