TOMAS - USE OF FORMULAS FOR CALCULATION OF PRODUCT PRICES AND MATERIAL TRANSACTIONS

TOMAS is a single system on the market that enables the user to use any type of formulas for various calculations. In other words, TOMAS accepts external knowledge and uses it in data operations.

Formulas are used in TOMAS for calculation of:

Elements that could be used in formulas are the following: Formulas in TOMAS could be structural or calculative.
With structural formulas price elements to be calculated are specified.
calculative formulas define how an price elements is to be calculated.

Structural formulas have the following content:

                code       description

                XXX         E1,E2,E3,E4,E5,
                   !            ----------------------
                   !                       !_ price elements
                   !_ structural formula code
 

Calculative formulas have the following content:

      code       description

       E5          (E1+E2)*E3/E4=
          !            ...........................
          !                                !_ how E5 is to be calculated, using other price elements
          !_ price element code

In general, the content formulas is the following:

 G              A,C,D,@E,F,

 A              A=                          to be taken from price register

 C             $A=                         A is corrected by % or amount registered in commercial conditions

 D              #K*A/100=            K= VALUE in product characteristic "K".

 E                                             to be taken from a constant (type = VRIJ, code = E)

 F              A+C-D*E=              any combination of previous price elements.

Effects of using formulas in TOMAS are the following:
