The bidirectional, validated interface between ERP (e.g. Majesty) and DOQ guarantees the effective exchange of data between both systems. This ensures a paperless process in production. The ERP remains the leading system and all changes (e.g. to current production orders - change of an operation to off-site operation, changed quantities or schedule changes) are immediately transferred to DOQ and updated. DOQ accesses the master data, collects all PDC and MDC data and transmits it to the ERP after completion of the operation. Withdrawn material can be registered via barcode and also reported to the ERP. Inspection documentation from CAQ systems is transferred to DOQ, signed and attached to the digital product creation file. The resulting digital product development files do not have to be printed out and can be transferred to a DMS for archiving.
