Hi,
in production we are using golden devices for callibration of equipment. During callibration process the device performs all required steps on the equipment. As a golden device can be reprocessed several times on the same equipment it should not influence KPIs as FPY etc.
From what I read in SAP ME 6.0 documentation I was sure that this scenario can be covered by ME 6.0 Golden Unit functionality:
"Golden Unit Indicates that SFC number has the Done status and is a perfect unit
SFC numbers in the Golden Unit status are excluded from calculations such as yield (see Golden Unit)."
"Golden Unit You use this activity to mark an SFC number as a golden unit. To become a golden unit, the SFC number should have the Done status. After testing, you can change the status of the SFC number back to Done (see SFC Number).
You use a golden unit to put equipment into test to make sure it works correctly."
When I tested this functionality I realised that Golden Units are not allowed to be started at any ME operation. This is also stated in a prior discussion in this forum (Golden unit functionality... incomplete getting error on status..)
I do not understand how testing and calibration of an equipment can take place without starting the golden unit SFC in ME, as all the ME web service calls of the equipment are part of testing if equipment works correctly.
Is there still no opportunity in ME 6.0 to actually use Golden Unit SFCs for fully testing equipment/ME processes?
If no, what customization would be needed to allow processing of golden units at certain operations?
Best Regards
