RE: System hangs up while posting PO/SO for more than 15-20 min in AX 2009

Hi, Pavin.

Could be a DataBase performance issue.

I suggest you two steps.

1.Try sql SQL SERVER PROFILER, use Tuning Template, in event selection select all, in column filter use Greater than or equal 2000; and try to do the operation stand alone.

You will get the time of all query´s involved and the time of it.  With this informatión you will understand the most time query.

2. Try to do a DataBase Mantenance, I suggest you begin with this blog:
