in the log I have the following error:
While doing exactly what and where? Providing full stack including all informations and process description would be helpful
1. what's wrong with this property ?
Apparently nothing, rather something with included value regarding your stack
2. what's the use of this property (I find nothing in doc/note/scn) ?
Unfortunately Im also not familiar with it, but could be release status of a km document / wpc article or something due description?
3. how to sove this ?
Is your SP on latest patches? If not, I would patch on spec
cheers
