To manage Multisite with Baan is not easy, you have to know very well the complete process between every plant (financial, manufacture, Transportation and distribution concepts).
Existe a good Baan MultiSite course and manual you have to read first of all.
For exemple if a Financial buy material for all the plants and the delivery is in each warehouse and you don`t want to make an invoice at those warehouses (taxes!!!), BaaN don´t manage the same receiving process in 2 dif. financial on the net.
The way I have solve this problem (a Mill company), is using NFS with a little file (ascii) between both financial and a T1 comunication network(64k), with all the datas you need, and apply the reception (FILE) on the consolidate financial with a little program in TCL/TK (Shareware) every time you need it.
Hope you understand and that can help you
Bien le bonjour
