This routine generates the demand of the previous month, classifies the sales and cost ABC as well as the type of price, and saves the formula of calculation of demand for each product, according to the questions answered in the window Parameters.

This process must be made at the beginning of the month, before generating the Purchase Suggestion.

During the processing, the new table Consumption File (SBL) is updated in 7 internal processes. They are:

• Monthly generation and update of SBL (Consumption File).
• Accumulation of Inflows - SD1 (Inflow Invoice Item File).
• Accumulation of Outflows - SD2 (Outflow Invoice Item File).
• Accumulation of Requests - SD3 (Request File).
• Sales ABC Classification.
• (Standard) Cost ABC Classification.
• Saving the demand formula chosen in the month for each product.

Types of Methods

The formulas used to calculate the demand can be:

Stability

aConsumption[nAtual-1]

Average

Average of last periods = (aConsumo[nAtual-1]+aConsumo[nAtual-2]+aConsumo[nAtual-3])/3

Tendency

aConsumo[nAtual-1]+(aConsumo[nAtual-1]-aConsumo[nAtual-2])

Seasonality

aConsumo[nAtual-12] * aConsumo[nAtual-1] + aConsumo[nAtual-2] + aConsumo[nAtual-3]
                                ____________________________________________________________

                                  aConsumo[nAtual-13] + aConsumo[nAtual-14] = aConsumo[nAtual-15]

You can also create a exclusive formula through Formula Register.
