The following dates are relevant for a material cost estimate and a costing run:
You can define a date control ID in Customizing for Product Cost Planning that determines the following:
The date control ID is assigned to a costing variant.
The quantity structure date determines how the system selects a valid quantity structure for the cost estimate. Based on this date, a BOM and a routing are selected, exploded and costed. The quantity structure date also determines which additive cost estimate is selected.
The valuation date determines how the system searches for valid data to calculate the following prices:
You set the validity period of the cost estimate with the Costing date from and Costing date to indicators.
You use the costing type in Customizing for Product Cost Planning to specify whether cost estimates are updated in the database with a date. You have the following options:
For costing types which have the With date or With start of period indicator set, the system uses the date or period start that is entered in the Costing date from field.
Depending on whether you carry out costing manually or automatically, you must remember the following:
You cannot create more than one cost estimate with the same validity period, because cost estimates with the same Costing date from would overwrite one another.
On the other hand, you can create automatic cost estimates whose validity periods overlap. In this case, the entries in the field Costing date from are different.
The validity periods of the additive cost estimates must not overlap.
The validity period of the cost estimate is also relevant for Cost Object Controlling. The results of the standard cost estimate are used in the calculation of:
If the standard cost estimate is not valid on the date on which these functions are to be performed, the system issues an error message.
