Pre-acquisition - noting this is not required - if you add them in it will apply to all products for all the styles. We would recommend instead that you create that on the master product instead of setting it up as system types.The colour and size matrix for Styles can be used for not only clothing but for other stock as well.
For clothing you can set up the colours and sizes for the products
For other items you can set up colours and maybe use the sizes as the size or type of the product (like colour: blue and size medium
You are able to set up the system types to auto-select the category and unit code for the style products. But this will mean that it is for every style and child product you set up.
Best practice is to ignore these system types altogether - leave the values for them empty in the system types and instead set up the Style master product to how you want the actual child products to be set up.
If you are wanting to preset the category and unit for EVERY STYLE PRODUCT YOU CREATE - see below:
System Type : Product : GENERATED-PRODUCT-CATEGORY [for Auto generated products]
System Type : Product : GENERATED-PRODUCT-UNIT-CODE [for Auto generated products]
Administration : Colours
Administration : Sizes
