BOM Cost Roll Automation

Two of our customers are using specific costs because of the highly variable cost of their materials. I’ve shown them how to do a cost roll but they receive materials on a daily basis and find the roll tedious.

I tried to setup an automation schedule to do the roll and update pending but the automation screen will not accept the screen id.

1. Is it possible to to automate this?
2. If so, what are the basic steps to do this?
3. If not, is there a reason it shouldn’t be?
4. Is there a setting to make BOMS pick up last costs whenever a production order is created?

I understand that the variance is important to see differences and track back what went wrong. Unfortunately the materials variance information becomes basically useless if frequent cost rolls are not done when using specific costs because, if I understand correctly, the production planned costs are based on the BOM while the actual costs are based on the last cost of the materials released.

Please feel free to disabuse me of any mistakes in my understanding of how costing works.

Thank you.
