Causes the system to display a lookup page.
There are three lookup options:
Default Lookup - The lookup into the table is performed without applying filters or other special parameters.
Field Lookup - You can use this trigger to define a field lookup that will be used in place of the default lookup.
Text box Lookup - You can use the OnLookup (Page fields) Trigger to define a lookup based on the value of a text box. This value will be used in place of the default lookup or the field lookup.
When using this trigger, follow this approach:
Use the field value to determine what filters or other parameters to apply.
Run the lookup page as a modal page.
Transfer the value the user selects back to the field when the user chooses OK.
If an error occurs in the trigger code, the lookup page is closed.
