No. this is not possible because of scrap or yield on the BOM. The only way is not to use scrap or yield but to build in an additional quantity for the component. For example set the quantity required to 1.1 rather than say qty = 1 and scrap = 10%. this is because it calculates that the additional 10% needed because of scrap also needs 10% etc so the calculated quantity would be 1.111111
Many thanks Phill for your prompt response. but current decimals is too much for some industry like chemistry actually the measurement standart no need such accurate, if QAD can setup some ccalulation control to round the decimals by the controlling parameter, that would be great for user to issue the material quickly, otherwise they have to manually change the quantity for each item. Hope QAD can provide such function by some patch. Thanks again.
