Required a Minimum Margin level at Company level, this is because at present some of the Vendors are not mapped with margin rule and another case is suppose user has passed 0 rate in Transaction then it has to b taken care off because it is being treated as 100% margin
Please map the margins in the article level as well (one time effort). In case the margin is not defined in the vendor-article level, system should automatically consider the margin at article level.
