Task

The supplier YML feed contains active categories 101 and 205, while archive category 999 must not be imported.

Short answer

If you need one category, set categoryId Equals 101. If several categories must be kept by one condition, use regular expression ^(101|205)$ (matches a value that is exactly 101 or 205).

How to do it in Eofferix
