Chapter 3. IDRS Terminal Responses

Section 15. Command Code ENMOD

2.3.15  Command Code ENMOD

2.3.15.1  (01-01-2000)
Entity Research (ENMOD)

  1. This Command Code is designed to provide name, address and other entity information from an input of the taxpayer identification number (TIN). It serves as a preceding step for keying command codes:

    • ENREQ

    • EOCHG

    • EOREQ

    • BNCHG

    • INCHG

    • EOCHG

    • ESIGND

    • ESIGNT

    • ESIGNU

  2. There may also be a variance in display for each type of entity modules. These displays are:

    • IMF—Individual Master File

    • BMF—Business Master File

    • NMF—Non Master File

    • IRAF—Individual Retirement Account File

    • EPMF—Employee Plan Master File

2.3.15.2  (01-01-2000)
Types of Entity Modules

  1. The different types of Entity Modules are as follows:

    1. Full Entity Module—This is an account for which at least one tax module is present on the TIF, or has been newly established within the last 15 months.

    2. ERAS ENTITY MODULE—(BMF, EPMF) This is a newly assigned EIN account which has not yet posted to the Master File. The record is comprised of Name and Address information, additional fields listed under Abbreviated Entities and data unique to ERAS, (Input Cycle ERAS Notice Indicator, Return Code, Tax Period, Wages Paid Date and Business Operational Date).

    3. Memo Entity Module (IMF/IRAF/BMF/EPMF)—There are two types of memo accounts. Memo entities are retained on IDRS for eleven weeks. They are the Resequence account which results from a completed merge. A "DI" TC 026 will be present for this type of acct. The Deleted account results from the deletion of the account from the master file as a result of TC020. A "RS" TC 903 will be displayed as a result of this action. Also the message "MEMO ENTITY" will be displayed on the screen.

    4. Dummy Entity Module—A dummy entity module may be present as the result of CC ACTON, CC ENREQ, or other activity. The message "DUMMY ENTITY" will be displayed on the screen.

    5. Partial Entity Module—A partial entity is one for which Name and Address data is not present on IDRS. The message "NO CURRENT NAME LINE/ADDR" with account will be displayed on the screen.

2.3.15.3  (01-01-2000)
Inquiry Responses for Command Code ENMOD

  1. After the initial inquiry, subsequent inquiries, by Command Codes (TXMOD and ACTON), for the same taxpayer do not require re-entry of the TIN. For example: CC ENMOD input after CC TXMOD requires only Command and Entry Code to obtain response.

2.3.15.4  (01-01-2000)
ENMOD Responses

  1. The response to Command Code ENMOD is divided into six sections. These sections will appear in this order. If one section is not applicable for the account, the subsequent sections will present immediately following the last filled Section.

    1. Section 1—ESTABLISHED ENTITY DATA SECTION: This will be present for all cases on IDRS. If the data element for specific information is not present, blanks will appear.

    2. Section 2—PRIOR YEAR NAME LINES: IMF, IRAF, & BMF SSN only—Name line data, for other than the current tax period, will be displayed with the applicable Filing Status Code and Spouse's SSN.

    3. Section 3—POSTED ENTITY TRANSACTION SECTION.

    4. Section 4—PENDING ENTITY TRANSACTION SECTION: This section will be present only if the account has a pending entity transaction.

    5. Section 5—ENTITY NOTICE SECTION: This section will be present only if the Taxpayer has been subject to entity notices.

    6. Section 6—CONTROL AND HISTORY DATA SECTION: If applicable will be shown as the final Section. Format will be the same as CC TXMOD Control and History Data Section.

2.3.15.5  (01-01-2004)
Terminal Response (Error Messages) from CC ENMOD

  1. INVALID TIN AND FS—TIN/File Source does not meet standard validity checks. Correct and re-enter.

  2. xTIF NOT AVAILABLE—File indicated is not available (x-B, I or Z).

  3. SYSTEM ERROR ON ACCESS/UPDATE-NNNNNN—Irrecoverable error when attempting to find account on the file NNNNNN is error code. Notify RPA.

  4. NO DATA-REVERSE VALIDITY FOUND—No data is available for the validity requested but data is present for the opposite validity. Re-input ENMOD with the opposite validity of the original inquiry.

  5. SYSTEM ERROR-REENTER-NNNNNN—Temporary error condition exists. NNNNNN is error code. Re-enter.

  6. NO DATA FOUND ON THE TIF —The requested data is not present at the TIF, but the National Account Index (NAI) database.
