I have been having a problem for a while that manufactured parts with Std cost would periodically have the Std material cost go to 0 for seemingly no reason. I have been able to isolate this problem to this. After performing a full inventory roll up in the costing workbench, any part with a std material cost that has an on hand qty of 0 will have the cost changed to $0.
Part Site tab (NOT General) says Costing Method is Last or Average, so Standard doesn’t roll up. On the same tab, is part marked as Non-Stock?
Only approved Part Rev is in the future. Cost Roll Up posting date is 1 November 2018 but rev goes into effect 7 November. So while there are parts on the MOM, they are not in effect on the roll up date.
The Mom contains purchase parts with no material values and/or no hours.
I have to say that even in E9, the on-hand qty should not make a difference. At least I have never seen it happen. You should be getting a roll up of $0.0529 per piece. There needs to be some other reason.
I would look at the costing method of the material and what that cost is and then the costing method you re using for the rollup in the costing workbench and the cost of the material for that method.
If the costing workbench is using Std, check the std cost of that material. Average, Last, etc.
If you check the checkbox for use the material costing method. Check that.
Make sure you have the materials listed in the materials tab and what the cost for the material shows before the rollup.
If all of that jives, I’m stumped and would have to stop by and look at it. I’m in Fort Worth.
