Interface between quotation data and costs database

A prototype is created as the basis for discussions with the specialist department. In the course of the ongoing support, the application was converted from MS Access 2.0 to MS Access 97 and adjusted to new requirements (structural changes, Y2K adjustment, EURO changeover). The quotation data is available in the form of multiple Excel calculation sheets (work packages and power plant components). The task of the application is to import this data into a conversion program, to validate the data and to convert the structures to the target system (costs database). Before the data is transferred, a visual check of the data integrity takes place in a dialog (by means of check totals).
