Occurs when the program is doing any type of calculation and a there is a problem with the calculation
It is often caused by problems with formula in parts or products where a section of the formula (in a specific case) is evaluated to zero or a very small number.
A calculation may be something like, optimising parts, creating parts for a set of products, working out formula and variables in parts and products, dividing lists, calculating data for transfer to the saw. The calculation does not finish and the results (if any) are not useable. even if the calculation continues with the unaffected items.
Many errors that could cause this sort of problem are identified when you create or save the data (e.g. entering parts lists, machine instructions or formula) but in some cases the item can only be fully evaluated when the calculation begins and in these situations this error occurs. The error message usually indicates which, part, product or other item is involved and which field is causing the error.
Check the data carefully and re-try
Very occasionally this problem is caused by an internal error with the software so if you cannot easily resolve the problem check with your supplier.
For example, if you optimise a product requirements list in which a part in a product contains the following formula for Length this illustrates the error.
Length: =(X-25.0)/0
The problem occurs because an item in the formula is divided by zero.
