+/*
+    Current prescribing by VTM
+    =========================
+
+    Purpose:
+    Return patient-level prescribing records for all products under one
+    Virtual Therapeutic Moiety (VTM).
+
+    Data source:
+    REPORTING_DATASETS_ICB.SCRATCHPAD."MEDS__UnifiedPrescribingTable"
+
+    Notes:
+    - VTM is useful when you want all products containing the same therapeutic
+      moiety, regardless of brand, strength, or pack.
+    - The practice CTE is deliberately visible. Change the geography filter
+      there if the report should not be Norfolk and Suffolk.
