The user has reported that a Wave is still marked as “In Progress”, despite the fact that the corresponding order has already been shipped and billed.
Solution:
The most frequent reason a Wave remains “In Progress” is that there are associated pick tasks that are still ongoing. This represents a critical dependency within the WMS (Warehouse Management System) process.
Often, this issue arises when the Item Fulfillment was manually created via the NetSuite UI instead of being processed through the WMS, which results in the Pick Task not being linked to the Item Fulfillment.
