In Thailand there are 3 main physical sites: a 3rd party WH managed by DHL which has most of the stock (=WH1 in PRMS), Bangkok (BKK) and Chiang Mai (CNX) which are the Loanset warehouses, with limited space.
Currently DHL has agreement to replenish BKK twice per week as a maximum, as freight cost is high (A$100 per trip). Therefore some level of safety stock needs to be kept in BKK and CNX.
It is envisaged that DHL will replenish directly both BKK and CNX in the future.
