Anil K Patel commented on OFBIZ-4444:
-------------------------------------
IMO, this business requirement should be handled little differently. We should
first generate Market Basket analysis report from Order data and then based on
user defined criteria "Also bought" product assocs should be created.
> createAlsoBoughtProductAssocs service does not work
