Hi all, I am using the conversion tool to convert the library from cdb to oa. I always encounter some warning and this particular error while performing. It would be nice to know more about the error and why the tool from assura is called while performing the conversion. Thanks a lot cheers Dinac ***************************************************** WARNING (CDBOA-639): There is more than one shape on the layer prBoundary in the cellview cells253cell/xn21d4/abstract.
