How can I use a internal table, defined in component controller method, in action/method of view

[Former Member]

Hi experts..

I am beginner to Web dyn pro..

My problem is:

I have created a internal table in one of method of component controller and keeping some records there.

I want to use the records of the internal table in the methods or actions of the views embedded in the controller.

I also tried to define as global attribute but no solution.

the lines of the code is as:

method disp

DATA lo_nd_ztab TYPE REF TO if_wd_context_node.

    DATA LT_ZTAB TYPE STANDARD TABLE OF WD_THIS->ELEMENT_ZTAB.

    DATA lo_el_ztab TYPE REF TO if_wd_context_element.

    DATA ls_ztab like LINE OF lt_ztab."wd_this->element_ztab.

*   navigate from <CONTEXT> to <ZTAB> via lead selection

    lo_nd_ztab = wd_context->get_child_node( name = wd_this->wdctx_ztab ).

    lo_el_ztab = lo_nd_ztab->get_element( ).

    IF lo_el_ztab IS INITIAL.

      exit.

    ENDIF.

DATA: ld_index type i,

it_rows  type WDR_CONTEXT_ELEMENT_SET,

wa_ztab LIKE LINE OF lt_ztab,

ls_selrow like line of it_rows,

ls_ztab1 like LINE OF it_rows.

  lo_el_ztab   = lo_nd_ztab->get_lead_selection( ).

  CALL METHOD lo_nd_ztab->GET_SELECTED_ELEMENTS

  RECEIVING

  set = it_rows..

  LOOP AT it_rows INTO ls_selrow.

    CALL METHOD ls_selrow->get_static_attributes

        IMPORTING

          static_attributes = wa_ztab.

    APPEND wa_ztab to lt_ztab.

    CLEAR wa_ztab.

  ld_index = sy-tabix. "index of selected row

   lo_nd_ztab->set_selected(

       flag = abap_true

       index = ld_index ).

  ENDLOOP.

endmethod.

"  I want to use the internal table LT_ZTAB.

pl help.

Hello,

you just need to create a global table.

put all your values in that table.

then you can access this table from the component controller.

Hi Lalit,

** You can now do what you want with this, store in in a global variable so that you

** If you do this you simply need to use context_node->set_selected to select all the

**   SELECT a row

   lo_nd_ztab->set_selected(

       flag = abap_true

       index = ld_index ).

*   DE-SELECT a row

*   context_node->set_selected(

*       flag = abap_false

*       index = ld_index ).

  ENDLOOP.

this is my code...

here i am keeping the records for the slected lines in the program.

after putting in the table, i m looping the int tab to perform the operation like save/delete etc, for the no of rows selected.

the code is working perfectly in the individual action button,

but I want to make it global and to access in the action button.

I tried to give various suggested attribute decl, but the system is saying not exists.

pl help. since I am new it is frusrated to find the exact solution/types.

Thanks,

Lalit

Hi,

How you created the node ZTAB in the context? Have you added the attributes individullay( by right click on Context node and create attribute) or by using DDIC reference?

If you have added the attributes individually(local), you need to create a DDIC structure with those attributes as fields in SE11 (say ZTAB_STRU) and then create a table type with the ZTAB_STRU as line (say ZTAB_TT) .

Then in the Attributes tab of your component controller, create an attribute with the created table type

gt_tab type ZTAB_TT.

hope its clear now!!

PS: please be little patient and don't be frustrated, which helps you in finding/resolving the issue.

I suggest you to go through the basics and then search the forums for more details.

Best Regards,

Kiran

Hi Lalit,

You need to find out the type used for context node.

go to your context node and check for the DDIC type used to create context node

Please refer the below snap shot for reference.

Now, use this structure/table and create a table type in SE11 eg. ZTT_RM_CLAUSES

Finally use ztt_RM_CLAUSES table type

Hope this helps you.

Hi,

In your component controller, create an attribute( in Attributes tab) say gt_ztab of type (your internal tabel type). Then

After getting the data to lt_ztab set it to the global attribute

using wd_this->gt_ztab = lt_ztab.

Then in your view(s), you can access the internal table data using

wd_comp_controller->gt_ztab.

hope this helps,

Hi Kiran,

Thanks for the reply.

I have tried to define as global attribute of the int. table lt_ztab, but system is saying ' The type lt_ztab  does not exist.

thanks,

Lalit

[former_member184578]

Hi,

You have to declare the associated type of lt_ztab not lt_ztab.

For ex: if you have internal table,

lt_flight type standard table of sflight.

Now you have to use the type as table type of sflight. not the lt_flight.

so, create a table type for the structure associated to the lt_ztab and then use that type.

hope it clears!

Regards,

Kiran

[ramakrishnappa]

Hi Lalit,

As suggested by Kiran, you need to use the type name used to create the local internal table lt_ztab.

In your case, you have defined the internal table lt_ztab by using context node reference.

Now, find out the DDIC name used to create your context node ZTAB and you need to get the table type for the same and use it to create global internal table at component controller.

Hope this helps you.

Rama
