##Evidence:
A2 refers to district names. PRIJEM refers to incoming transactions (credits), VYDAJ refers to outgoing transactions (debits). Net balance is calculated as total income minus total expense. Customer category is determined by loan count and transaction activity: High Activity (has loans and >10 transactions), Loan Customer (has loans), Active Customer (>10 transactions), or Regular Customer (others).

##Role Access Policy (Column-Level):
