When Dynamics GP posts to general ledger, it utilizes a temporary table called pjournal. The pjournal table resides in each company database in your environment. This is a temporary table and will slow down posting when records remain in it.
Per kb 898982 http://support.microsoft.com/kb/898982 you can delete all records from the pjournal table in each company database. I have found that to significantly increase the speed of posting.
If you find this to be an issue that you are experiencing, you can enable a job under sql agent called “Remove Posted PJournals”. This job will go through all of your company databases and clear the table. In order to enable the job, open SQL Server Management Studio and expand your server instance.
Expand SQL Server Agent and then jobs. Find the job entitled “Remove Posted PJournals”. Right click and choose properties. Mark the “Enabled” check box.
By default, this job runs every 30 minutes. If you want to change the schedule, you can right click on the job, choose properties and go to the schedule page.
