P43080 - Approvals Critical Fields by DCTO

Is it posible to use the DCTO to define the critical fields in the P43080? The standar record in this table F43080 has '**' in DCTO field. We add this field using Extension Form to change the '**' to an especific order type, but the test failed when I used a different DCTO (looks like this configuration applies to all documents).
