we can't to find which field of which table actually store the person who created the trip inbehalf of the employee. But I can only found the person who lastly change the trip in table
PTRV_HEAD field UNAME. Also what is the logic of when the field UNAME get updated, since for my testing, when another logon user change the trip's head data like date, reason this field get changed. But this field won't be change if the user only change the trip's line item data such as addition info, amount of the trip etc. Is it the real logic of the system?
Thanks in advance.
