+# 1. Goal
+
+A translation agency prices translation jobs. The order desk calls one function
+module for each job. The function module must have the same interface as the
+sample module {{P}}TRANS_SAMPLE, because the order desk calls all pricing modules
+of the agency in the same way. Other programs of the agency also need the price.
+Therefore the calculation is available in a separate class.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- Function group {{P}}FG_TRANS exists in package $TMP.
+- Function module {{P}}TRANS_SAMPLE exists in this group. It is the sample
+  pricing module. Its interface is the interface that all pricing modules of the
+  agency use.
+
+# 4. Contract
+
+## 4.1 Function module {{P}}TRANS_FEE
+
+- Function group: {{P}}FG_TRANS.
+- Interface: exactly the interface of {{P}}TRANS_SAMPLE.
+  - Importing parameters:
+    - iv_lang_pair TYPE string
+    - iv_word_count TYPE i
+    - iv_express TYPE abap_bool
+    - iv_certified TYPE abap_bool
+  - Exporting parameter: ev_fee TYPE decfloat34
+  - Exceptions: invalid_lang_pair, invalid_word_count
+
+## 4.2 Class {{P}}TRANS_PRICER
+
+- Package $TMP.
+- Public and final.
+- Public constructor without parameters.
+- Public instance method calculate_fee:
+  - Importing parameters:
+    - iv_lang_pair TYPE string
+    - iv_word_count TYPE i
+    - iv_express TYPE abap_bool
+    - iv_certified TYPE abap_bool
+  - Returning parameter: rv_fee TYPE decfloat34
+  - The method has no exceptions. It expects valid input.
+
+# 5. Business rules
+
+1. The language pair is STD or RARE. Any other value is invalid.
+2. The word count is 1 or more. A word count of 0 or a negative word count is
+   invalid.
+3. The function module {{P}}TRANS_FEE checks the language pair first and the
+   word count second. It raises the exception INVALID_LANG_PAIR for an invalid
+   language pair and the exception INVALID_WORD_COUNT for an invalid word count.
+4. The price of one word is 0.12 for language pair STD and 0.19 for language
+   pair RARE.
+5. The translation charge is the word count multiplied by the price of one
+   word. Round the translation charge half up to 2 decimals.
+6. The minimum translation charge is 35.00. If the translation charge is less
+   than 35.00, the translation charge is 35.00.
+7. The agency grants a volume discount on the translation charge after rule 6:
+   - 10 % for 1000 words up to 4999 words,
+   - 15 % for 5000 words or more.
+   Round the discount half up to 2 decimals. The discounted charge is the
+   translation charge minus the discount.
+8. A certified translation adds a flat fee of 22.00 to the discounted charge.
+9. Express delivery multiplies the amount after rules 7 and 8 by 1.5. Round the
+   result half up to 2 decimals.
+10. Without express delivery, the fee is the amount after rules 7 and 8.
+11. The class {{P}}TRANS_PRICER returns the fee in rv_fee. The function module
+    {{P}}TRANS_FEE returns the fee in ev_fee.
+
+# 6. Constraints
+
+- Release target: 8.16 (SAP_BASIS 816).
+- Package $TMP. Do not use a transport.
+- Clean ABAP. Keep every method below 40 statements.
+- Out of scope: do not change {{P}}TRANS_SAMPLE.
+
+# 7. Acceptance
+
+- All objects are active and have no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests: local test classes for {{P}}TRANS_PRICER and a global
+  test class for {{P}}TRANS_FEE.
