database table "NC_DATA " in field "Closure Required" shows always "false"

Hi

I'm working on creation of a BO-Report on protocolled issues (NonConformance) on the SFC.

now I see, that in the database table "NC_DATA" the field "closure required" is always on "false" although the NC-Code has true or false.

What is the intend of this field in the table?

the BO-Guide "DB Guide 6.0" says, the field was "true", if this NC must be closed.

Thanks in advance

Yvonne
