DisablePostIncludes needs to be enabled (True) to prevent the ITPRun command from post-including document into the result document (to process the __INC expression in result documents). Note that post-includes in ITP/Server are performed lazy by default (ITPLAZYPOSTINC=Y). If not set or set to False, the ITPRun command will use the ITPPOSTINC setting in the itp.cfg to determine if post includes have to be processed
