Hi,
Picking in Dynamics 365 Finance & Operations can be done in two different ways.
First approach:
You generate a picking list, which acts as a task list or document for warehouse workers indicating which items and quantities need to be picked.
Once the physical picking is completed, the process is finalized by posting the picking list registration.
This approach is commonly used in larger warehouses, where warehouse execution and system posting are handled by different users or at different points in time.
Second approach:
In smaller or faster-paced operations, users often perform direct picking, where picking and registration are completed in a single step.
Because of this process design, posting a picking list registration without first generating a picking list does not really align with the intended flow, as the picking list is the document that drives the registration.
Regarding automatic posting of the packing slip, To my knowledge, there is no standard out-of-the-box functionality that automatically posts the packing slip immediately after picking is completed. Packing slip posting is intentionally kept as a separate step, as it typically represents the physical shipment confirmation.
It would be helpful to understand the business requirement behind automatically posting the packing slip at the time of picking. In most implementations, picking and packing are treated as distinct operational steps.
Could you please share the business scenario you are trying to achieve?
