Number of lines joined to the table
This parameter is used to optimize the display of tables/grids with a large number of lines present in an object management. It defines the maximum number of lines of the table/grid to be transferred from the server to the customer during the first stage of display.
This is used, when viewing several records with a large number of lines in a row, to do so quickly while avoiding a too lengthy transfer time of several seconds.
The complete loading of a grid/table only occurs when switching to the modification mode in the grid/table, or when an operation has been performed on the grid/table, such as a scrolling, a right click or a column sorting.
When the grid/table is not totally loaded, the 
icon appears in the left top corner. A click on the icon concerned is also used to reload the grid/table.
