In our system, Travel Planning is disabled, because we don't want online booking. Travel services button is active in Travel Request, because we do want some basic information for each service.
I would like to know what's the best approach to store data of custom fields for each travel service.
Right now, I know how to add fields in the main view, using PTK99 structure, user exit, and enhancing the WDA application thanks to Lukas Weigelt.
Any help would be appreciated.
