Dynamically loading a table

[Former Member]

Hi,

Can anyone help me out with this...

I've a table in my UI. But depending on various actions clicked on the screen i need to bring in different set of values and attributes on to this table.

Is there any way out to bind a table dynamically in the program based on the requirement (or click). Basically i want to load different tables into the table element in the UI at different button clicks.

Regards,

Jomy

Hi George

in the WDDOMODIFYVIEW of your view you can use this method to create a table dynamically and bind it dynamically.

CL_WD_DYNAMIC_TOOL=>CREATE_TABLE_FROM_NODE

Hi all,

I've found this method pretty useful. But i can't quite understand its signature. This is the calling method

CALL METHOD CL_WD_DYNAMIC_TOOL=>CREATE_TABLE_FROM_NODE

EXPORTING

UI_PARENT =

TABLE_ID = tbl_results

NODE =

• ON_LEAD_SELECT =

RECEIVING

TABLE =

This is the signature given

Importing UI_PARENT UI Container in which Table Is to Be Located

Importing TABLE_ID Table ID

Importing NODE Reference to the Context Node

Returning VALUE( TABLE ) Reference to New Table

therefore, what are the parameters that i need to send?

Hi all,

I have the same problem. I don't know which values the method needs. The reference to the node is clear, but the table id and ui parent is not clear. Has anybody a documentatio resp. an example?

Thanks in advance for your help.

Hi Marcel,

You can use the following code. It will dynamically create a node and table. This is for ALV table. So you just have to Instantiate the ALV Component and Use Set data method after that. You would be able to see your data in the ouput.

If you would like to change the structure after any button even, you can use Remove Node method and again call the code to create a dynamic node and table.

***********************************************************************************************

DATA: node_info TYPE REF TO if_wd_context_node_info,

struct_type TYPE REF TO cl_abap_structdescr,

table_type TYPE REF TO cl_abap_tabledescr,

comp_tab TYPE cl_abap_structdescr=>component_table,

comp LIKE LINE OF comp_tab,

my_table TYPE REF TO data,

my_struc TYPE REF TO data .

FIELD-SYMBOLS: <table> TYPE table,

<strc> TYPE data,

<table1> TYPE table,

<data> TYPE ANY .

comp-name = 'COL1'.

comp-type ?= cl_abap_datadescr=>describe_by_name( 'DATA ELEMENT' ).

APPEND comp TO comp_tab.

comp-name = 'COL2'.

comp-type ?= cl_abap_datadescr=>describe_by_name( 'DATA ELEMENT' ).

APPEND comp TO comp_tab.

• this structure contains the abovefields

struct_type = cl_abap_structdescr=>create( comp_tab ).

• now the nodeinfo is created

node_info = wd_context->get_node_info( ).

node_info = node_info->add_new_child_node(

name = 'DYN_NODE'

is_mandatory = abap_true

is_multiple = abap_true

static_element_rtti = struct_type

is_static = abap_false ).

*----If you could create a local data type, would be fine, but if you

• have to do it dynamically ...

struct_type = node_info->get_static_attributes_type( ).

*---Create tabledescriptor from structdescription

• (standard table, no keys)

table_type = cl_abap_tabledescr=>create( p_line_type = struct_type ).

CREATE DATA my_table TYPE HANDLE table_type.

ASSIGN my_table->* TO <table1>.

CREATE DATA my_struc TYPE HANDLE struct_type.

ASSIGN my_struc->* TO <strc>.

• the above code creates table and a node with 2 columns COL1 and COL2.

• To Remove Node

DATA: node_info TYPE REF TO if_wd_context_node_info.

node_info = wd_context->get_node_info( ).

node_info = node_info->get_child_node( 'DYN_NODE' ).

node_info = node_info->get_parent( ).

node_info->remove_child_node( 'DYN_NODE' ).

Let me know if that helps or if you need more Info.

Thank You,

Hi Gajendra,

thanks for your reply. When I use the add_new_child_node method it works fine, but when I use a static node and add dynamicly the attributes I get errors. Thanks so far for your help!

hi george.......

you can make use of the class cl_wd_table.... which has the method bind_data_source... for practice you make use of the method bound_data_source.... which will give you an idea of how the values must be passed.
