RE: Workflow Inventory Worksheet
I don’t believe it is possible to create workflows for “Inventory Worksheet” transactions. This transaction type replaces inventory values REGARDLESS of what the prior values were. It is typically used sparingly and only by administrators (I’ve only ever seen it used when setting up inventory upon account creation or after an inventory count that resulted in massive inventory swings), so it kind of makes sense that they wouldn’t build workflow functionality around it.
What you’re probably looking for is the “Inventory Adjustment” transaction type, which is available for workflow creation (scroll up a bit on your sub types and you’ll see it (unless you’ve renamed your transaction types)). This is for adjusting individual item quantities up or down by a specified amount.
If you DO need a workflow specifically for the “Inventory Worksheet” transaction type, I would really push back on the person asking or the specific inventory processes that are generating that requirement to understand why.
