Introduction :
SAP has provided Collective search help to meet most of the requirement. Incase if we want to add or hide any function in Collective Search Help it can be done by following the steps given in this document.
Assumption :
The Web-Dynpro Component is created in which based on the class values (KLAH-CLASS) , we are getting other details from KLAH table. Search Help assigned to the field Class is Standard Collective Search Help ( /PLMB/CLF_CMP_CLAS ). We are going to hide two of the search helps and add another search help new to the Standard Collective Search help.
Explanation about the Standard Collective Search Help:
Collective Search Help - /PLMB/CLF_CMP_CLAS. (It is designed for the Class Field).
It contains following Search Helps :
/PLMB/CLF_ELM_CLASA - Find using Key Word
/PLMB/CLF_ELM_CLASB - Find using Class Number
/PLMB/CLF_ELM_CLASC - Find using Class Group
/PLMB/CLF_ELM_CLASD - Find using Din Class
/PLMB/CLF_ELM_CLASE - Find using Standard
/PLMB/CLF_ELM_CLASF - Find using Document
Now we are going to hide two Search Helps, /PLMB/CLF_ELM_CLASE , /PLMB/CLF_ELM_CLASF and add New Search Help to search the class value based on the field SICHT "Organizational Area" from KLAH (Class Header Table)
(1) Search Help Output at Present in Web Dynpro Component : (Understanding what is the current output of Search Help).
( i ) Below image shows the Web Dynpro Component implemented with the field Class (KLAH-CLASS) and search help assigned at the dictionary level to the field Class in Web-Dynpro is /PLMB/CLF_CMP_CLASS . Based on Class Value other fields are fetched from the KLAH table once the user clicks submit. We are going to do some modification on the F4 help assigned to the Class field (/PLMB/CLF_CMP_CLAS).

Fig 2.8 Hidden Search Help are not shown
Hidden Search help are not shown . Other than the 2 hidden Search help , 4 search help are listed. You can compare the Fig 2.8 and 1.2 for understanding the Change.
(3) Adding a new Custom Search Help criteria :
( i ) In addition to hiding the standard Search help , you can also create a new custom search help, if the requirement is not satisfied by the standard.
Here we are adding another new Search help, to search the class value based on the field Organizational Area (SICHT from KLAH table) .
New Search help ZORGAREA is created in Included search help ZCLASS_SH. Ensure to provide Parameter Assignment. This step is important to assign selected value from the Search Help to field.

(ii) Click on the Search Help ZORGAREA and fill the required parameters.

We have filled the parameters Organizational area and Class as we are going to search class based on Organizational area value from KLAH Table (Selection Method - KLAH ).
(iii) Output of the Web-Dynpro Component.
On clicking the F4 of the Class you can view new Search Help "Find using Organizational Area" available.
Fig 3.4 Find using Organizational Area
Fig 3.5 Total Search Help list (2 have been hidden from the standard and 1 custom have been added )
I want to select one class from the Organizational area 'S'. So in search criteria, I have filtered the Organizational area as 'S' and clicked start search.
Fig 3.6 Selecting Organizational Area as 'S'
Fig 3.7 Showing the result based on search Criteria.
Now the list of Class values having Organizational Area as 'S' is displayed. On selecting the value from search help, the value of the class is displayed in the UI.

The above are the steps to Change / Hide the standard Search Help in collective Search help which is assigned to a field.
