Activities

• The system retrieves all activities of this user by name
• The system retrieves all activity records of this user (Activity & Amount)
• The activity records are parsed by the system:

• For each activity, the positive entries are summed up -> Consumed
• For each activity, the negative entries are summed up -> Paid (transformed to positive value)
• For each activity, the difference between the two values above (Consumed - Paid) is calculated -> Remaining (positive) / To be paid (negative)
