+# 1. Goal
+
+A telephone company rates the calls of its customers. The rating program
+collects the data of one call and calls one function module for this call. The
+function module must have the same interface as the sample function module,
+because the rating program calls all rating modules in the same way.
+
+# 2. Open questions
+
+None.
+
+# 3. Context
+
+- Function group {{P}}FG_TEL exists in package $TMP.
+- Function module {{P}}TEL_SAMPLE exists in this group. It is the sample rating
+  module. Its interface is the interface that all rating modules must use.
+- A call has a call type, a destination zone and a duration in seconds.
+
+# 4. Contract
+
+- Create the function module {{P}}TEL_RATE in function group {{P}}FG_TEL.
+- Use exactly the interface of {{P}}TEL_SAMPLE:
+  - importing parameter iv_ctype, type string,
+  - importing parameter iv_zone, type string,
+  - importing parameter iv_secs, type i,
+  - exporting parameter ev_minutes, type i,
+  - exporting parameter ev_charge, type decfloat34,
+  - exception invalid_duration.
+- iv_ctype is the call type of the call. iv_zone is the destination zone of the
+  call. iv_secs is the duration of the call in seconds.
+- ev_minutes is the billed duration of the call in minutes.
+- ev_charge is the charge of the call.
+
+# 5. Business rules
+
+1. If iv_secs is less than 0, raise the exception INVALID_DURATION. ev_minutes
+   and ev_charge stay 0.
+2. ev_minutes is iv_secs rounded up to the next full minute. 1 to 60 seconds is
+   1 minute. 61 to 120 seconds is 2 minutes. 121 to 180 seconds is 3 minutes,
+   and so on. If iv_secs is 0, ev_minutes is 0.
+3. The price of one billed minute depends on the call type and on the zone:
+   - call type NT: zone A 0.09, zone B 0.19, zone C 0.29
+   - call type IT: zone A 0.19, zone B 0.39, zone C 0.59
+   - call type MO: zone A 0.29, zone B 0.49, zone C 0.69
+   - call type SP: zone A 0.39, zone B 0.59, zone C 0.79
+4. If the call type is not NT, IT, MO or SP, or the zone is not A, B or C, the
+   price of one minute is 0.
+5. If ev_minutes is 0 or the price of one minute is 0, ev_charge is 0.
+6. Otherwise ev_charge is ev_minutes multiplied by the price of one minute plus
+   a connection fee of 0.025. Round ev_charge half up to 2 decimals.
+
+# 6. Constraints
+
+- Release target: 8.16.
+- Package: $TMP. Do not use a transport.
+- Out of scope: do not change {{P}}TEL_SAMPLE.
+- Coding standards: Clean ABAP. A method has fewer than 40 statements.
+
+# 7. Acceptance
+
+- The function module is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests for the function module in a global test class.
