PFHT (Manufacturer price excluding taxes) :
Price at which the product is purchased by the pharmacy
Formula for calculating the weighted average PFHT :
For a given period and a given GTIN:
Sell-in / Sell-out ratio multiplied by the weighted average selling price of the product ( PVMP )
Weighted average PFHT = N WASP x (Sell-in N / N To)
Limitations : It is calculated for one GTIN at a time
