+# 1. Goal
+
+A farrier serves stables with a mobile shoeing round. The order desk calls the
+function module {{P}}FARRIER_FEE once for each planned visit. The module returns
+the fee of the visit, the number of weeks until the next visit, and a flag that
+tells the desk that the visit must not be planned.
+
+The module already exists in package $TMP. Its implementation is old code. The
+code works, but it mixes several rules in one block and it uses hard-coded
+numbers. Rewrite it so that a new colleague can read and change it.
+
+The name and the public interface of the module must not change. The result of
+the module must not change for any input.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- The function group {{P}}FG_FARRIER exists in package $TMP.
+- The function module {{P}}FARRIER_FEE is in this group and is active.
+- The order desk and two planning programs call the module. They rely on the
+  current interface and on the current results.
+
+# 4. Contract
+
+Function module {{P}}FARRIER_FEE in function group {{P}}FG_FARRIER. Keep the
+name and the interface. Do not add, remove or rename a parameter.
+
+| Name | Kind | Type |
+| --- | --- | --- |
+| iv_horses | importing | i |
+| iv_km | importing | decfloat34 |
+| iv_new_shoes | importing | abap_bool |
+| iv_contract | importing | abap_bool |
+| ev_fee | exporting | decfloat34 |
+| ev_weeks | exporting | i |
+| ev_reject | exporting | abap_bool |
+| invalid_horses | exception | - |
+
+# 5. Business rules
+
+The rules of the shoeing round are in the current implementation of
+{{P}}FARRIER_FEE. Read that source. Every rule that the current code applies
+stays in force. The module must return the same values as before for every
+combination of input values.
+
+# 6. Constraints
+
+- Release target: 7.58.
+- Coding standards: Clean ABAP. Give every value a meaningful name. Replace
+  hard-coded numbers with constants. Keep the procedures short and comment each
+  rule.
+- The module stays in package $TMP.
+- Out of scope: none.
+
+# 7. Acceptance
+
+- {{P}}FARRIER_FEE is active and free of syntax errors.
+- The returned values are unchanged.
+- The hidden tests pass.
+- Add ABAP Unit tests for the module in a global test class.
+- No ATC finding of priority 1 or priority 2.
