CodeCop Warning AA0181

The FindSet() or Find() methods must be used only in connection with the Next() method.

Description

Avoid getting the dataset when an enumeration is not used, which will decrease performance.

Reason for the rule

If you use FindSet() or Find() you must have a Next() method. Otherwise, you are wasting CPU and bandwidth since multiple records are loaded but you only use one.

Bad code example

codeunit 1 MyCodeunit
{
   var
      customer: Record Customer;
                
   procedure Foo()
   begin
      if customer.FindFirst() then
         repeat
         ...
         until customer.Next() = 0;
      end;
}

Good code example

codeunit 1 MyCodeunit
{
   var
      customer : Record Customer;
                
   procedure Foo()
   begin
      if customer.FindSet() then
         repeat
         ...
         until customer.Next() = 0;
      end;
}
