Had this terrible issue with Navision Value Entries form. Whenever the form was opened from the Item Card Navision would freeze did a profile in SQL for all the SQL statements and found that the system was taking time to execute a command which started like sp_cursorfetch.

Some RND and found that the sp_cursorfetch is implemented by the database library to manage the cursors at the server side. Before a cursor fetch can be issue a cursor open statement has to be declared which would contain the base statement for the cursor. Once i found the statement being used for the cursor i did a execution plan display and found that it was not using the correct index.

I then updated the statistics for the index using the Update Statistics command we all know that statistics decide the selectivity of an index once this was done the cursor started using this index and the issue was resolved.
