There are various options for storing or reading product data in MK|Ware. The variants are listed below. MKWare_AddItem MKWare_AddItemSN MKWare_AddItemSNValues MKWare_GetItemByGUID MKWare_GetItemBySN MKWare_GetValuesByGUID MKWare_GetValuesBySN MKWare_GetInsertValuesBySN MKWare_InsertValuesByGUID MKWare_InsertValuesAnonymous MKWare_InsertValuesByGUIDChangeSN General The following conditions generally apply to product data collection: Uniqueness In product data collection, the serial number is unique for each product by design. This is ensured by the database design. This means that a serial number for the same product can be requested at several points of use, and it is incremented internally until it is successful. Deletion of data records The deletion of product data is not technologically supported. Archiving Archiving can be done by (automated) exports. The format corresponds to the open XML-based Microsoft Excel format, including all levels of detail such as formatting. At the same time, a Microsoft SQL server database backup also serves as an archive. Product characteristics Additional columns can be added to a product data table at any time. Columns can also be hidden. Values are retained and, if still configured, continue to be recorded. Overwriting values The values for a serial number can be overwritten multiple times and are stored as history entries. Only the last entry is displayed in the table view and the export. This technology is often used for rework parts. Plausibility of the values After successfully saving the values for a serial number, the unique GUID in MK|Ware is automatically reset for security reasons. This means that it is not possible to save values without the machine control system (PLC) first updating the product GUID.
