+# 1. Goal
+A driving school shows its lessons together with the instructor of each lesson.
+A report and an OData service read the data. The data must be prepared in the
+database, in a CDS view. The view exposes the instructor data of a lesson
+through an association.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}INSTR (instructor), package $TMP. Key: INSTR_ID (CHAR 10).
+  Fields: FULL_NAME (CHAR 30), CITY (CHAR 20).
+- Table {{P}}LESSON (lesson), package $TMP. Key: LESSON_ID (CHAR 10).
+  Fields: INSTR_ID (CHAR 10), LESSON_DATE (DATS), DURATION (INT4, in minutes),
+  FEE (DEC 15,2).
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_LESSON_INSTR in package $TMP.
+- Elements, with these names: LESSON_ID (key), INSTR_ID, LESSON_DATE, DURATION,
+  FEE, INSTRUCTOR_NAME, INSTRUCTOR_CITY, and the association _INSTRUCTOR.
+- The association _INSTRUCTOR points to the table {{P}}INSTR. Its ON condition
+  compares the INSTR_ID of the lesson with the INSTR_ID of the instructor.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. The view shows one row for each lesson that lasts at least 45 minutes. Do not
+   show a lesson that is shorter than 45 minutes.
+2. LESSON_ID, INSTR_ID, LESSON_DATE, DURATION and FEE are the values of the
+   lesson.
+3. INSTRUCTOR_NAME is the FULL_NAME of the instructor whose INSTR_ID is the
+   INSTR_ID of the lesson. INSTRUCTOR_CITY is the CITY of that instructor.
+4. A lesson whose instructor does not exist is still shown. INSTRUCTOR_NAME and
+   INSTRUCTOR_CITY of that lesson are empty.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP.
+- Out of scope: do not change {{P}}INSTR and {{P}}LESSON.
+
+# 7. Acceptance
+- The view is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
