I want to create a new search help in va42 or va43 for the contract. Can some one explain me how to achieve this.
When you include a new search help to 'VMVA', this will add every screen wherever its used. We can make it to add only at VA42 or VA43 transaction via search help exit SD_F4_SHLP_EXIT_SUBSHLP_CHOOSE.
To be more specific, in this function module SHLP_TAB internal table holds all the search helps. U can add/delete existing search helps dynamically based on transaction Code. And also have a note this is standard FM you need access key to change this FM.
Hope this help.
