I have a rule in the schema that creates WT 8500.
Next, I have to create an additional rule, that depending on some conditions must recalculate the same WT.
The problem is that instead of recalculating the WT, the rule is adding the new 8500 to the first one calculated in the previous rule.
I make the calculations and put: ADDWT 8500 at the end of the rule ( that adds the new amount to the old one)
Any suggestions on how to clean the first 8500 before calculating it again?
