Search Help in Select - Options

[Former Member]

Dear experts,

i use three select options and they work fine.

In the node of the view i declared the attributes i need and bound a search help (F4 help) to them.

here is the problem.

One attribute has the help visible when i start the application, the other two not.

Can you give me a hint how to solve this ?

Thanks and best regards

Hi Rene,

I had the similar question earlier, later what i have found is like this:

1. I have a WDC with three Select options to it.

2. First Select options relates to the first attribute in my context node which takes the Data element as the Data type. For Ex: take BUKRS as the DE. This has pre-defined search help to the DE C_T001.

3. Second select options relates to the second attribute in my context node which takes the string as the data type. I manually assigned the Search help to that attribute 'C_T001'.

4. Thirs Select options relate to the third attribute inmy context node which takes the string as the data type. I manually assigned a Search help to it 'H_T002'.

5. In the WDDOINIT of my view, I have written the code as follows in the bottom of the post.

6. The observation is the search help assigned to the first attribute will be opened with out any problem or additional code to it.

7. The search help assigned to the second one at the context level wont be picked in the select-options.

8. The search help assigned to the third one will be picked if and only if there is manual assignment of the search help at the time of creating a selection field.

Conclusion: So, the search help assignment assigned to the attribute at context level is ignored. It will be considered only if the DE has that search help in the case of select-options.

Hope it is clear and appreciate your feebback.

Hi Rene,

According to me i guess you want to set the search help for the atribute which do not have search help set to it . If that is the case then i guess you might be using the add_selection_field( ) method for select options. In that method we have an option to set the search help or OVS into that

call method wd_this->m_handler->add_selection_field

exporting

i_id = 'the attribute name for which you want the serach help option to be set''

• I_WITHIN_BLOCK = MC_ID_MAIN_BLOCK

i_description = 'Project Decsription'

• I_IS_AUTO_DESCRIPTION = ABAP_TRUE

it_result = lt_range_table

i_obligatory = abap_true

• I_COMPLEX_RESTRICTIONS =

• I_USE_COMPLEX_RESTRICTION = ABAP_FALSE

i_no_complex_restrictions = 'X'

i_value_help_type = if_wd_value_help_handler=>co_prefix_appldev

i_value_help_id = 'USE_OVS' "if you are using ovs set the OVS name here

• I_VALUE_HELP_MODE = 1 "it will disable the f4 functionality

• I_VALUE_HELP_STRUCTURE =

• I_VALUE_HELP_STRUCTURE_FIELD =

• I_HELP_REQUEST_HANDLER =

• I_LOWER_CASE =

• I_MEMORY_ID =

i_no_extension = abap_true

i_no_intervals = abap_true

i_as_checkbox = abap_false

• I_AS_DROPDOWN = ABAP_FALSE

• IT_VALUE_SET =

• I_READ_ONLY = ABAP_FALSE

• I_DONT_CARE_VALUE =

• I_EXPLANATION =

PLz check the below links for more details. hope you will be more clear.

hi,

my problem now is that the field help will only be displayed if its bound to the data element directly.

How can i display the field help for the personnel number. Here the field help is bound to the field itself.

Thanks and best regards

Hi Rene,

If you are binding these attributes to the input fields of table thn i dont think you will be able to see the search help button unless you click on the input field... we were facing similar concerns are were not able to sort it out..... if it is simple input fields there must not be any problem..... in that case provide some more details...
