Factory Explorer® v2.2 Technical Alert #4
Summary: In Factory Explorer® Excel® models, leaving an inactive product (no DATA keyword) in the model can cause problems if the process flow specified by the inactive product is also specified by an active product lower on the Products worksheet. This error is fixed in Factory Explorer® v2.3 beta 2.
Details: In Factory Explorer® Excel® models, rows that do not contain a DATA keyword in the first column are treated as inactive by Factory Explorer® and are not included in the model. One way of removing a product from a model, i.e. inactivating it, is to simply erase the DATA cell in that product's row. However, if the process flow specified by this inactive product is also specified by an active product entered later on the Products worksheet, Factory Explorer® does not correctly write out the process flow. Instead, Factory Explorer® skips over the process flow, mistakenly believing that it has already been written out (for the inactive product). This can lead to an error when Factory Explorer® attempts to read in the model's process flows (there may not be enough flows), or it can cause Factory Explorer® to mix up the process flows for the model (if the model was run previously and the intermediate process flow files are still on disk).
Workaround: When removing products from a Factory Explorer® Excel® model, delete the entire row on the Products worksheet, rather than simply erasing the DATA keyword.
