Forecast

As for long-period calculations, results exact to the minute are not necessary. A fast mode of calculation is provided here: gross calculation. The material requirements are determined using the function "calculate resources" and must not be broken down at the time of the calculation of the purchase recommendation any more.

Important:

If this method is activated, the material requirements must be calculated first for all assemblies concerned, or after greater changes.

Requirement coverage calculation is not available, but balance calculation is.

Example

Finished part "A" - semi-finished part (storage related) "W" - purchase part "P"

stock "W" = 2 pieces

requirement "A" = 5 pieces

Net requirement calculation results:

A = 5 pieces, W = 5 pieces, purchase part "P" = 3 pieces, because W is covered from stock (requirement coverage calculation)

Gross calculation

A = 5 pieces, W = 5 pieces, purchase part "P" = 5 pieces, because no requirement coverage calculation is performed.

Resource scheduling (MRP2) is based on lead time calculation. Therefore  "gross calculation" must be deactivated if resource scheduling is required.

Item setting "multiple order" is not considered. Order-related assemblies are not displayed (they have no effect on balance calculation)

See: Calculate resources

The function should be activated only for extensive long period forecasts.

The function per default is deactivated.
