Gross requirements determination
The requirements calculation for products of all procurement types which
are to be procured is structured in detail. In doing so, the following
factors are taken into account when calculating the gross requirement:
• Production list base
• Number
• Length, width
• Conversion factors for the length and width unit
• Absolute scrap, start up quantity, absolute quantity required
• Scrap percentage
• Use
• Rounding specification
The specifications can be recorded by the user in the product master files
screen. All specifications will be used by preliminary costing (for pricing)
and scheduling (in order to calculate the gross requirements).
Data taken into consideration in the scheduling run:
• Sales orders
• Open purchase orders
• Open work orders
• Purchase order suggestions
• Work order suggestions
• Scheduling mode
• Stock level, minimum stock level, lot sizes, grouping of lots in specified
time intervals, procurement lead times, production times,
organizational- and procedure-related wait times, transitional periods,
maximum stock level and package size
• Gross requirements determination by means of the quantity, length
and breadth specifications with the respective conversion factors,
production list bases, absolute scrap, use and rounding specifications.
