Freeze estimated order-costsYou can freeze the estimated end-item unit costs to enable a good comparison between actual and estimated unit costs. The moment of freezing estimated costs is determined by the Moment Freezing Estimates check box in the Production Orders (tisfc0101s000) session. After you freeze the estimated end-item unit costs you cannot change:
You can change the following according to the latest schedule changes:
If you freeze the estimated costs, and if changes are made to one of the following:
Then the change does not influence:
In production planning changes can occur in:
When a change occur after freezing in the scrap & yield percentage, LN adjusts the planning of:
If after freezing, changes are made to the ordered quantity in the production order, LN adjusts (taking Scrap & Yield factors into account) the:
Example A production order has the following data. Quantity ordered = 100 pcs
Assume the estimates are frozen. When changing the Yield from 80% to 50% on operation 20, the allocations of materials are updated based on the new quantities. The estimated quantity is still related to resp. 127 and 125 pieces respectively. The new situation is as follows:
When changing QTY ordered from 100 pieces to 150 pieces the estimated costs and the planning change again. The new situation is:
The estimated material costs are based on the estimated yield of 80%, which results in the quantities 187,5 and 189,5 pieces.
