>"Structural incompatibilities" is that the same as "undocumented >feature"? No. It is a general problem, but since I could bore for England on the subject of data hierarchies, I will give a concrete example. An application exports order data using a simple hierarchy of header and detail records. Unfortunately they choose to put the order number in the detail. In the EDI hierarchical structure the order number appears in the header. The simple minded strategy is to deal with the incompatibility by picking up the order number from the first detail record and mapping it to the header. But what happens if the order number changes in the detail iterations? You have to start a new transaction, which means a fair amount of scripting to detect the change and recreate a new header for it. Ideally you would sort the detail records by order number first to avoid the possibility of order number duplication in different transactions. This has happened to me on several occasions.
