Replace LockTable with IsolationLevel

[Arthurvdv]

The Directions EMEA event inspired me to add some rules for applying best pratice in the area of performance. This isn't about Lintering exactly anymore, but I guess it could be a part of the LinterCop anyway?

One of there would be to always replace the LockTable with a IsolationLevel.

Does anybody known an scenario where we still need a LockTable in favor of the IsolationLevel?

procedure WithLockTable()
var
    ItemLedgerEntry: Record "Item Ledger Entry";
begin
    ItemLedgerEntry.LockTable();
    ItemLedgerEntry.FindLast();

    // Some Code here
end;


procedure NoMoreLockTable()
var
    ItemLedgerEntry: Record "Item Ledger Entry";
begin
    ItemLedgerEntry.ReadIsolation := IsolationLevel::UpdLock;
    ItemLedgerEntry.FindLast();

    // Some Code here
end;
