Q: Where does that Last Cost for a part number come from?
 
When I do an inventory inquiry, it shows the last cost as 3 times what we sell the product for.  We have the same sequence number set up for all parts.  We do this for ease of input of the labor.  
 
Q: When we enter this, should the last cost be based upon this?  
Q: Also, is the parent part cost based upon the labor input for that as well as the cost of all child parts?
 
Since we set up the ability to input labor, the cost of all of our products have been incorrect, they are all more than they should be.

Thank you for your response, I did some looking into this.
When I started this, I was refering to manufactured parts, not purchased parts, although there seems to be a problem with those as well.
 
I checked under RO-C and all dollar amounts ar $0.00.
 
When I check a part, I want the last cost to be the value of all the labor and material that went into making that part.  When I check a parent part that contains these child parts, I expect the last cost of the parent part to be the sum of all the child parts as well as labor and material to finalize the parent.
 
When I check the price of some of the purchased parts of this through IN-A, I have a last cost at $55.60, Avg Cost at $0.00 and Std Cost at $57.00.  I am seeing this all over, although the PO for that part shows $55.60 each, the average cost is zero.
Q: How can this be corrected and/or where does this come from?
 
For instance, when I print a BOM at average cost, some of the manufactured parts have $0.00 for both Avg Cost and Extended and some have prices, although IN-A shows a value for the last cost.  It is the same for some of the purchased parts.
Q: How can this be fixed?
 
Q: Is there a help file for DBA that actually works, that can be searched and show an index?  Mine has ???? on each tab.
