If you would ask me if I would write something about SAP Script then I would definitely answer "Hell no!". I hate SAP Script to be honest, it has for me only one advantage - speed of printout if you compare it to Adobe Forms, but the rest for me..... is against.
Today I faces a really strange behaviour of one of the invoice printouts, one of the fields which was showing the tax percentage, was showing wrong value if the print program was called for the second time.
The first output was OK, 8,00 % as value.
But when I directly show again the preview of the same invoice then, the value was changed to 0,80 %.
