Recently, while running the fixed asset projection routine in Dynamics GP 2010, the network connection was lost. After resolving the issue and going back into GP, the user found the projection button was grayed out in fixed asset routines. There is a kb article on customer source and many blogs available on this subject and most say to delete the records in the FA41900 table. This actually did not work.
I found a kb article on Microsoft’s public site 856544, which also indicated the FA40203 table needed to be deleted. This resolved the issue. http://support.microsoft.com/kb/856544#appliesto
