When creating a production task, the input products are not calculating relative to output product.

Hi,

We are mounting up accumulation orders successful SAP ByDesign. I person built retired the BOM's created a BoO and accumulation model. All works fine, but erstwhile I person a accumulation bid for output quantity 100 it is not multiplying input quantity to match.

e.g. earthy worldly (steel) is utilized to marque a component, for 1 portion requires 0.033m of steel, you would expect input products to beryllium 100 x 0.033m (3.3m) for the 100 finished products. 

What is apt incorrect successful the accumulation model, BOM oregon BoO which is causing this not to calculate?
