Expense mobile app - passing worker's financial dimensions to travel expense report

Hello All,

I want to pass worker's financial dimension to the expense report's (TrvExpTable) default dimension.

i can set it before insert() call in TrvExpTable. but this would become applicable for all expense entries happening from AX client and EP.

Is there a way where we can know that entry is being made by mobile app and pass default dimension of the worker there.
