Just to add to this rant - we all use Excel, we buy it for a couple hundred bucks a license, and nobody ever checks the values in a column to make sure the “Sum” function is actually correctly summing the values.
With ERP software, the assumption is that it won’t work, and that has to be determined and fixed prior to implementation.
Being that ERP software is one hell of a lot more expensive than a spreadsheet, it seems to me that our ERP suppliers have lost vision of their customer’s needs. The assumption that it works properly is only made by the folks creating the code. The marketplace fully understands that it’s highly likely that the product will not work as advertised.
