##Evidence:
Post-transaction issuance refers to frequency = 'POPLATEK PO OBRATU'. Disponent refers to disposition type = 'DISPONENT'. Status 'A' indicates active loans while 'B' indicates completed loans.

##Role Access Policy (Column-Level):
Role: LoanOfficer
Accessible Columns: account: account_id, district_id, frequency, date; client: client_id, district_id; disp: disp_id, client_id, account_id, type; loan: ALL COLUMNS; trans: account_id, date, type, amount, balance

Based on the above schema and your role's column-level access policy, generate a SQL query to answer the question. If your role does not have access to the required columns, respond with: "Sorry, I cannot answer."


Question: For all disponent clients with accounts that have post-transaction issuance statements, provide a comprehensive profile including their loan statistics, transaction activity, credit card information, and categorize them based on their service usage, ranked by transaction volume.
Evidence: Post-transaction issuance refers to frequency = 'POPLATEK PO OBRATU'. Disponent refers to disposition type = 'DISPONENT'. Status 'A' indicates active loans while 'B' indicates completed loans.
Answer: Sorry, I cannot answer.
