Advantages of data replication
Rather than use table sharing by means of the logical linking of tables, you can replicate the content of tables between companies. The advantage is that, on company level, some (non-key) attributes of a record can differ by company. For example, if the bills of materials are replicated instead of shared, for each company, you can link a different warehouse to the bill of material. As a result, the bills of materials can be the same across all companies and only the warehouses differ. Using replication, you can also make only a subset of the records available in other companies. For example, if you replicate items between companies, in a sales company, for example, by means of the item group, you can only make end items available.
In addition, you can replicate only a subset of items, for example, depending on the item group.
Note that replication also requires that the referenced tables are replicated or shared.
