+# 1. Goal
+A blood donation centre checks a person before it takes a blood donation. The
+check is one function module. The function module rejects a person who may not
+donate. A rejection is a class-based exception. The exception tells the caller
+the reason for the rejection and the waiting time.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Function group {{P}}FG_DONOR exists in package $TMP.
+- The centre uses class-based exceptions for rejected checks. The exception
+  class for this check does not exist yet.
+
+# 4. Contract
+Exception class {{P}}CX_DONOR_CHECK in package $TMP:
+- The class is public and final. It inherits from CX_STATIC_CHECK. Its creation
+  type is CREATE PUBLIC.
+- The class has these public attributes:
+  - MV_REASON, type string: the reason for the rejection.
+  - MV_RETRY_DAYS, type i: the number of days after which the person may try
+    again.
+- The constructor has the importing parameters IV_REASON (type string) and
+  IV_RETRY_DAYS (type i, default 0).
+
+Function module {{P}}DONOR_CHECK in function group {{P}}FG_DONOR:
+- Importing parameters:
+  - IV_AGE, type i: the age of the person in years.
+  - IV_WEIGHT, type decfloat34: the weight of the person in kilograms.
+  - IV_HB, type decfloat34: the haemoglobin value of the person in grams per
+    decilitre.
+  - IV_DAYS_SINCE_LAST, type i: the number of days since the last whole-blood
+    donation. The value is 99999 if the person never donated blood.
+- The function module raises the exception {{P}}CX_DONOR_CHECK.
+- The function module has no exporting and no changing parameters.
+
+# 5. Business rules
+The function module checks the rules below in the given order. The first rule
+that matches raises the exception. The function module does not check the other
+rules after a match.
+
+1. If IV_AGE, IV_WEIGHT, IV_HB, or IV_DAYS_SINCE_LAST is less than 0, raise the
+   exception with reason INVALID_INPUT and 0 retry days.
+2. If IV_AGE is less than 18, raise the exception with reason TOO_YOUNG and 0
+   retry days.
+3. If IV_AGE is greater than 65, raise the exception with reason TOO_OLD and 0
+   retry days.
+4. If IV_WEIGHT is less than 50, raise the exception with reason UNDERWEIGHT
+   and 0 retry days.
+5. If IV_HB is less than 12.5, raise the exception with reason LOW_HB and 0
+   retry days.
+6. If IV_DAYS_SINCE_LAST is less than 56, raise the exception with reason
+   TOO_SOON. The retry days are 56 minus IV_DAYS_SINCE_LAST.
+7. If no rule matches, the person may donate. The function module does not
+   raise an exception.
+
+The reason is the value of the attribute MV_REASON of the exception. The retry
+days are the value of the attribute MV_RETRY_DAYS of the exception.
+
+# 6. Constraints
+- Release target: 8.16 (SAP_BASIS 816).
+- Use Clean ABAP. Keep every method below 40 statements.
+- Out of scope: no other objects.
+
+# 7. Acceptance
+- The exception class and the function module are active and have no syntax
+  error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
