IndexmanagementService XIndexing documents failed on PCDSearchIndex

Question

Hi,
I have an issue with and index created to search through the pcd. I have created an index as defined in the following link and have selected Portal Content in my index datasource.
http://help.sap.com/saphelp_nw2004s/helpdata/en/b2/d59a4271c80a31e10000000a1550b0/content.htm
When I click on reindex, I get the following error message:
Operation failed Method not supported on PCDSearchIndex.
If I open the Application Log, I get the following error message every minute.
IndexmanagementService  XIndexing documents failed. Method not supported on PCDSearchIndex. Continue crawling... 
Anyone has an idea on how to fix this issue?
Thanks
Renaud

Hi Renaud,
no need to fix here, just don't try to reindex manually
PCD Index function is completely different than other indexes in CM / TREX.
See also your referenced docu page: 'A schedule for automatic indexing is not required.'
Background: PCD search index perform a search against the user's role content.
When a user logs into portal, the content of the user roles is completely loaded into the PCD cache and kept in memory. Thus performing a search is very fast as it happens in memory (no need to load content from DB or filesystem).                                                                               
So you'd better not try to index or crawl the PCD repoitory. Those methods are 
not supported and implemented - as stated in the log.
