Estimation is the first of the update jobs in the production life cycle. For more information about the various steps in the life cycle, see About the production process.

Use the query function to select the production order to estimate. For more information about querying for production orders, see the Inquiry (form).
In the form, click to run the estimation. When it is complete, the status of the production is .
Depending on the selections that you make, a number of steps take place when you run estimation.
The following information describes the steps in the estimation process.
Explosion of phantom lines
If a BOM line contains the , it is exploded when estimation is run and the following actions occur:
The phantom line is deleted.
The BOM lines in the BOM item that the phantom line pointed to are inserted in the BOM and replace the deleted phantom line.
The route to the BOM item that the phantom line pointed to is inserted in the production route.
For more information, see Line type.
Calculation of references
If this option is selected under the tab, any production references attached to the production order are calculated, including all subproductions. The field is always selected on productions that have not yet been estimated. If you clear it, the estimation includes only what is done in the internal production.
Calculation of item consumption and creation of inventory transactions
The item consumption is calculated per BOM line. Consumption is calculated as the quantity specified for the BOM line times the production quantity, taking any conversion factor from BOM units to inventory units into account.
During this process, inventory transactions are created for component items. If there is material consumption (positive quantity specified) for a component item, you can create an issue transaction with an status. If, on the other hand, there is item profit (negative quantity specified), you can create a receipt transaction with an status.
Creation of purchases and subproductions
If the production BOM contains BOM lines of , you can create either a purchase or a vendor production: If the item has a item type, you can create a vendor production or you can create a purchase order for the item.
If there are BOM lines of in the production BOM, you can create a subproduction for the item. The item must, however, be of the item type because productions only can be created for this type of item.
Calculation of route consumption
The route consumption is calculated. Quantity-dependent time (process time) is calculated on the basis of the production quantity because time is calculated according to the "process time per quantity" for the work center and the production quantity. Quantity-independent time (setup time) is calculated based on the times specified for the individual work centers, regardless of the production quantity.
Reservation of items
Reservations of the estimated item consumption for the BOM lines are made. Whether or not reservations are necessary depends on the settings in the field for the production order.
Cost estimate of sub-productions
Estimations are calculated for any subproductions. A cost estimate of subproductions goes through all of the estimation steps described here.
If there are BOM lines of in a subproduction, a new subproduction subordinate to the first is created, which again goes through all the steps described here.
This step includes the price calculation of the production, its subproductions, and their subproductions. For more information, see Production - Price calculation (class form)
