Thanks for bringign this up to my attention: the only times that can
changed are the actual times... so yes, the label were not clear enough.
I've changed them to:
Estimated Setup Time
Actual Setup Time
Add Actual Setup Time
Estimated Run Time
Actual Time
Add Actual Task Time
This is in SVN with rev 5671.
Si, I greatly appreciate this kind of comments because they really help
me to improve the parts of the system that are not clear.
So if you see wrong labels, bad names etc... please do not exitate to
contact me and I'll fix them.

This is a good point: as it is now, the MRP process just searches in the
future for the product's demand (approved sales orders, production runs
etc...) and then sees if in warehouse the product's needed qty will
cause the product to go under the minimum stock level; if this will
happen, a new requirement is created.
If I'm not wrong, your situation is different: you have a product
already under the minimum stock level but no future demand for it (no
sales orders or production run), so no requirements are created.
I'm not sure if the MRP should take this situation into account or not:
however you can have a nice report of the under level products from the
Facility --> Inventory Items --> View Inventory by Product
With that report in hand, you can create purchase orders to refill the
stock levels (but this will never happen when the supply strategy is
driven by MRP).

Please, could you give me more details? Do you mean the requirements
generated by MRP or requirements generated by the 'automatic' methods
set at product or product store level?
