Site cost problem

Hi All,

Do any one experience a company use for many site (inventory site). I got inquiry how AX can fixed the multiple “site” for below: -

example: a company own 3 sites. the inventory ID is share between the sites.

- Each Item ID is using item dimension to hold color.

example: Item A, color: red, std cost: 100

Item B, color: blue, std cost: 100

Site 1, site 2, site 3 shared same std cost

what is the best practise to maintain the “standard cost” instead create 2 color dimension x (3 sites) = 6 rows std cost

for same cost?
