If the target table is a dimension you will be asked if you want to generate a get key function. The get key function is used by QAD Data Warehouse Designer for rapid prototyping. It returns the artificial key when passed the business key. Although this function is possibly not necessary in the existing environment it is useful if the dimension is to be used in any expansion of the data warehouse. If an existing get key type function exists, then this can be used, although changes will probably need to be made to the generated procedures to utilize this existing get key function.
