Find technical information to add custom search help
Find the technical information for the specific search help by clicking F1. Below shows the Search help for CJI3 transaction and find the table name as V_PRSMP
Using “where-used” find the specific search help that uses the table
Below is the search help which uses that view.
Check PRSMP search help and find that it is an elementary search help. So, check if there is any other search help linked to it. Found the search help PRSM using “where used”
Below screen shows PRSMP is linked to PRSM search help.
The search help PRSM is a collective search help.You can find the corresponding user exit in which the breakpoint can be set to understand how it works or check on the individual search help in the ‘Included search helps’ option.
Add custom search help to standard.
Created a custom search help as below with the selection method as a view which fetches the result
This view has a join with table PROJ
There can be other kinds of search help you could create. Below shows another example of a search help having selection method and search help exit.
For this requirement an elementary search help as my custom code and added it in the collective search help “Included search help” Section as below.
After debugging there seems to be some parameter missing which caused the issue of not being able to populate the value from the search help. Read more on the section below
Multi-selection search help did not return any values.
Using Multiple selection button user needs to populate more than 1 WBS elements
Custom search help was created as seen below
User can choose to select multiple options as seen below and click on green button to proceed ahead.
There was no value returned
Fix search help not returning result issue:
To start debugging popup since you cannot type /h to debug just drop the file on the GUI for the specific screen which has pop up and you would open up the debug screen
Found in debugging a parameter missing which caused the issue. There was a missing assignment of the elementary search help to the collective search help. Assign button was clicked and then copy this helped to fix the issue and the selection of the search help was returned back on the display screen.
