How to apply ABC Item classification to picking logic in RWMS

Hello everyone,

Our customer are using ABC (A-class items - most frequently picking items, B-class items - frequently picking items, C-class items - seldom picking items) logic during picking (by someone it could be called XYZ-classification, does not matter).

From season to season Item picking frequency changes (standard situation).

The same approach in replenishment and picking is requested from customer to obtain in RWMS.

After investigation I did not find anything regarding ABC Item classification in the RWMS.

Could you please advice what workaround could be applied in RWMS to satisfy this valuable customer requirement?

(I thought to use Attributes, but did not find how to apply attributes for replenishment, and picking flows...)
