+# 1. Goal
+A bookbinding workshop prices binding jobs. The order desk calls one function
+module for each job. The function module calculates the fee of the job and
+reports whether the job is a rush job.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_BIND exists in package $TMP.
+- Function module {{P}}BIND_SAMPLE exists in this group. It shows the interface
+  that the order desk uses.
+
+# 4. Contract
+- Create the function module {{P}}BIND_FEE in function group {{P}}FG_BIND.
+- The interface of {{P}}BIND_FEE:
+  - importing iv_binding TYPE string
+  - importing iv_pages TYPE i
+  - importing iv_member TYPE abap_bool
+  - exporting ev_rush TYPE abap_bool
+  - changing cv_fee TYPE decfloat34
+  - exceptions invalid_pages
+
+# 5. Business rules
+1. If the number of pages is less than 1, raise the exception INVALID_PAGES.
+2. Set the rush flag to false, except in rule 7.
+3. Binding type PB: the fee is 0.05 per page, rounded half up to 2 decimals.
+4. Binding type HB: the fee is 0.12 per page, rounded half up to 2 decimals.
+   The minimum fee for hardback binding is 15.00.
+5. A member receives a discount of 10 % on the fee. The discount is the last
+   step of the calculation and is applied after the minimum fee of rule 4.
+6. The minimum fee of rule 4 is the last step of the calculation and is applied
+   after all discounts.
+7. Binding type EX: set the rush flag to true. The fee is 0.20 per page,
+   rounded half up to 2 decimals.
+8. Other binding types: the fee is 0.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP.
+- Out of scope: do not change {{P}}BIND_SAMPLE.
+
+# 7. Acceptance
+- The function module is active and has no syntax error.
+- Write ABAP Unit tests for the function module in a global test class.
