I'm finding success in mapping certain CP fields to fields in CM (CPLOCATION or Tags work great). But fields such as AU_DOCUMENT_KEYWORDS_STRING is a field that does not appear to be exported. We also do not see any errors in the process. It is an IDOL field that is indexed during a Full Content index and pulled from the Tags field in the File property Details. The field does not appear to be ported over to any other field in the Advanced properties.
Are there fields that cannot be exported from CP, or any specific configuration to get ready to be exported then mapped?
