Error QE503- in QE11 transaction (results acquisition) for Equipment calibration

Hi Gurus

I'm working on QM-PM environment to set-up a Equipment Calibration process.

I've defined a  routing for Equipment, and I've linked few Quantitative Inspection characteristics to the PM Order Operation.

When I run IP10 to schedule the Maintenance plan defined for the equipment, the system create fine a Lot Inspection.

When I try to set the inspection result using QA32/QA11 the system isssue the Error  "QE503-Enter a valuation for this qualitative characteristic"

rather Inspection charactristics are defined QUANTITATIVE !!

Where is the error ??

Thanks in advance for your help.
