Cannot create "Digital" measuring points on Work Manager 6.0

Hi All,

I am attempting to create "digital" i.e. Pass/Fail measuring points in Work Manager 6.0. I can enter readings as shown below but when I execute a sync, the error message below is shown:

I can use the same measuring point in SAP via IK11 as shown below to create a measuring document using valuation code only. However, the Work Manager requires a numeric characteristic to be added and the "no reading" checkbox to be ticked.

Any help would be greatly appreciated.

Thanks,

Jonathan
