Dynamically change search help associated with a field

[Former Member]

Hi all,

I have a field on my web dynpro app which is associated with a table field and displays fine with the correct search help. Is there an easy way to dynamically change the search help it uses? For example could i add some code to the WDDOMODIFYVIEW method which changes which search help this field used based on certain criteria?

Hi,

You can achieve this feature without writing any code in WDDOMODIFYVIEW.

*Get the reference of context node information

Data: lo_node type ref to if_wd_context_node.

data lo_node_info type ref to if_wd_context_node_info.

lo_node = wd_context->get_child_node( 'Your context node name' ).

lo_node_info = lo_node>get_node_info( ).

*To set the search help, call the method

CALL METHOD lo_node_info->set_attribute_value_help

EXPORTING

name = 'Your attribute name with which you want to attach search help at run time''

value_help_mode = 101

value_help = 'your search help name of component usage name as per the search help selected'

Below values of value help mode you can use

deactivated = 101,

automatic = 111,

ddic = 121,

ovs = 131,

application_defined = 141,

Add this code to appropriate hook method or action handler which decides at run time for the value help attachment.

Thats great thanks very much,

just on question though how do i get the 'search help name of component usage name as per the search help selected'. Say if i wanted to display the standard search help 'PREMN' how would i go about getting a component usage for this or is that not how it works?

Hi

in the same method suppose if you want to use the ovs help then input help mode will be OVS ( number related to it ) and value_help parameter will have component usage name.

Same goes with freely programmed search help

in case of dictonary search help, just pass the search help name in CAPS in value_help parameter

Thanks

Hmmm my mistake indeed if you set it to 121 you can simply enter a SAP search help i.e.

CALL METHOD context_info->set_attribute_value_help

EXPORTING

name = 'DEPT'

value_help_mode = '121'

value_help = 'PREMN'.

Am sure i tried that before an it didnt work, oh well it does now so thank you very much. Dont suppose you know how I would implement this into a table. For example if i want the same field on different rows to use a different search help. I have got the following code to find the specific row of the table but am not sure how to assign the search help to just this row. any ideas?

Data: context_node TYPE REF TO if_wd_context_node,

lr_element TYPE REF TO if_wd_context_element.

context_node = wd_context->get_child_node( name = 'CONTEXT').

lr_element = context_node->get_element( ld_tabix ).
