ACTON - Used to establish, update, close control bases, correct name controls on dummy accounts and enter history items on IDRS modules. A valid input of CC ENMOD, SUMRY, TXMOD, LPAGD, ADJ54, FRM34, FRM77, STAUP, DRT24, DRT48, ACTON, or REINF must precede each ACTON input request.Examples:Establishing a new control base: ACTON 02 202312 AZURC#,REJECTCASE,A,TPRQ*,*The tax period and MFT are required when ACTON follows ACTON, ADJ54, DRT24, DRT48, FRM34, FRM77, LPAGD, REINF, STAUP, or SUMRY when establishing a control base (C#).
