1. A method for producing a desired metal workpiece (134), the method comprising:
producing an elongate finished material (116; 222) by hot rolling, wherein a first data record (112) is assigned to the finished material (116; 222), wherein the finished material (116; 222) is logically divided in the longitudinal direction thereof into a plurality of first segments (118), wherein the first data record, for each of the first segments (118), includes first physical data (228) characterizing the segment;
working the finished material (116; 222) using a processing process to obtain the desired metal workpiece (134), wherein the processing process is at least partially controlled based on the first physical data (228) characterizing the first segments (118) that are logically assigned to the finished material (116:222), wherein
working the finished material (116; 222) comprises collecting second physical data (208) of those first segments (118) which are logically assigned to the finished material (116; 222) to be worked; and
the first physical data (228) is checked for plausibility using the second physical data (208),
based on the plausibility check (240) measuring systems (224) being optimized, by which at least one of the first and second physical data (208) was collected, or based on the plausibility check (240) the working of further finished material (116; 222) to be produced by hot rolling being adapted or halted.
