Task
The supplier YML feed contains active categories 101 and 205, while archive category 999 must not be imported.
Short answer
Add an export condition to the offer node: categoryId must match the regular expression ^(101|205)$ (matches a value that is exactly 101 or 205).
How to do it in Eofferix
In the XML/YML snapshot, select the repeated
offernode.Open the node settings.

The animation shows opening the repeated product node settings. Add an export condition for
categoryId:categoryId^(101|205)$.
The condition is applied to the whole item.

- Place the condition on
offerso the whole product is excluded. - If the category list is long, keep it separately and update the expression deliberately.
