Re: Dynamic formulae calculation in RPG

Ewart,

You should keep it simple and easy to read, hence easy to modify and easy
to debug by coding it exactly how you have it written down in your
requirements:
/free
 Base = Qty * Price;
 Tax1 = Base * .02;
 Tax2 = Tax1 * .03;
 Total = Base + Tax1 + Tax2;
/end-free

You could of course make it impossible for the next programmer to
understand what you are doing:
/free
 Total = Qty * Price * 1.0206;
/end-free

Hello All,

We have a complicated Invoice calculation process where a lot local taxes
are to be considered. In order to make these calculations dynamic I plan
to do the calculations using dynamic formulas so that any future changes
can be considered.

Eg:

Description             Name            Formula         Value
Base value              Base            Qty * price             1000
Tax1 20% of base        Tax1            Base * .02              20
Tax2 30% of Tax1        Tax2            Tax1 * .03              0.6
Total                   Total           Base + Tax1 + Tax2      1020.6


Has anyone built something like that & can share the code - I can save
some time.

Thanks & best regards
Ewart
