+# 1. Goal
+Calculate the emptying fee for one septic tank. The depot program calls one
+function module for each emptying job. The function module must have the same
+interface as the sample function module, because the depot program calls all fee
+modules in the same way.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_SEWER exists in package $TMP.
+- Function module {{P}}SEWER_SAMPLE exists in this group. It is the sample fee
+  module. Its interface is the interface that all fee modules must use.
+- A drainage company empties septic tanks. The depot program sends the size of
+  the tank, the distance from the depot, and the connection type of the
+  property.
+
+# 4. Contract
+- Create the function module {{P}}SEWER_FEE in function group {{P}}FG_SEWER.
+- Use exactly the interface of {{P}}SEWER_SAMPLE:
+  - importing iv_tank_litres type i
+  - importing iv_distance_km type i
+  - importing iv_mains_sewer type abap_bool
+  - exporting ev_skip type abap_bool
+  - changing cv_fee type decfloat34
+  - exception invalid_litres
+
+# 5. Business rules
+1. If iv_tank_litres is less than 1, raise the exception INVALID_LITRES.
+2. Set the skip flag to false. Rule 4 is the only exception.
+3. The base fee is 75.00. The base fee covers the first 1000 litres of the
+   tank.
+4. If the property is connected to the mains sewer, no emptying is necessary.
+   Set the skip flag to true and do not change the fee. Do not apply rules 5
+   to 7.
+5. Each started 500 litres above 1000 litres adds 20.00 to the fee. Example:
+   1000 litres add 0.00, 1001 litres add 20.00, 1500 litres add 20.00, and
+   1501 litres add 40.00.
+6. The travel fee is 1.50 for each kilometre of iv_distance_km. The travel fee
+   is not more than 60.00.
+7. The fee is the base fee of rule 3 plus the volume fee of rule 5 plus the
+   travel fee of rule 6. The fee is not more than 900.00.
+
+# 6. Constraints
+- Release target: 7.40 SP05. Use only syntax that exists in 7.40 SP05. Do not
+  use syntax that is newer than 7.40 SP05.
+- Out of scope: do not change {{P}}SEWER_SAMPLE.
+- Coding standards: Clean ABAP. A method has less than 40 statements.
+- Out of scope: no database access, no ALV, no dynpro.
+
+# 7. Acceptance
+- The function module {{P}}SEWER_FEE is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
