The application of RAS-SU requires prior knowledge of the row and column sums of the matrices in question. The Euro method avoids this limitation; however it is only applicable tosquare matrices and it is not always convergent. In this paper, the global updating method is adapted to supply and use tables. The main focus is on indicating how rectangular matrices can be adjusted, without the need of any prior manipulation, and on ensuring the convergence of the results obtained. The global updating method is based on a distribution of the differences between vectorial estimations. It is more generic than the RAS method, and offers more routes to action. In general, one has to consider the relative weights attributable to each differential distribution. Needless to say, the availability of additional in formation in relation to the matrix structure would lighten the task.
