Part 2. Information Technology

Chapter 4. IDRS Terminal Input

Section 58. Command Code DDBCK / DDBCV / DDBCS

2.4.58  Command Code DDBCK / DDBCV / DDBCS

2.4.58.1  (01-01-2007)
Command Code DDBCK / DDBCV /DDBCS

  1. Command Code (CC) DDBCK/DDBCV/DDBCS is used for validating additonal children and credits claimed on amended returns (1040X). Command code DDBCV is the view only version of DDBCK without the update capability. Command code DDBCS is a selection setup screen used to monitor and modify work plans day to day, week to week and site by site.

  2. When DDBCK/DDBCV request is entered with the Primary TIN of a return, it displays the dependents & qualifying children from the original posted return or as last modified. By entering update request into DDBCK, a user can then modify the data to reflect changes from the submitted 1040X.

  3. After transmitting changes entered on the update screen, DDBCK/DDBCV validates any new TIN against INOLE, DUPTIN database and Dependent Database (DDB) rules. Messages are then displayed on the screen when

    1. If the TIN or Name Control does not match INOLE data

    2. If child is deceased or does meet the age criteria to qualify for a credit

    3. If DUPTIN database indicates a duplicate use of a TIN

    4. If a DDB rule is broken

    If the claim is valid, DDBCK automatically updates the DUPTIN database (DUPOL).

  4. The DDBCK Validation Result Screen will instruct the user on how to proceed with the case. If the case does not meet exam criteria, account management can process the adjustment as usual, but if the case needs to be classified or meets exam criteria, it should be sent to exam.

  5. The use of command code DDBCK has been restricted to Accounts Management and Examination. No other function should be allowed access. Command code DDBCV has not been restricted. It can be used by all functions.

2.4.58.2  (01-01-2007)
Command Code DDBCK Input Format

  1. The required input for CC DDBCK/DDBCV is:

    1. Command Code

    2. Blank Definer

    3. Edited TIN (nnn-nn-nnnn)

2.4.58.3  (01-01-2007)
Command Code DDBCK Return Summary Screen

  1. The DDBCK Return Update Screen shows the following information from the original return or as amended:

    1. DLN, received date and filing status of original return

    2. The date the information was last modified by DDBCK.

    3. Filing status of original return and filing status as amended

    4. TINs from the return, Name control, date of birth, date of death for each TIN and what credit was claimed for each TIN.

    5. A ‘Y’ under a credit indicate that it was claimed on the original return. An ‘A’ indicates that it was later added and a 'D' indicates it was deleted.

    6. If the TIN on the original return was invalid, ‘INVLD SSN’ will be displayed under the SSN/AMEND column, and if the name control was invalid, a ‘*’ will be displayed next to the name control. A 'x' in the credit field indicates that it was disallowed when the return was filed.

  2. If the posted return is not found for the SSN entered, an error message will be displayed. If the SSN is a secondary or was merged, it may indicate another SSN to research.

  3. Informational messages that is pertinent to the case may be displayed on the lower half of the screen. If the SSN has an open AIMS, math error, O freeze, or if the EITC recertification indicator is significant, a message will also be displayed on the screen. If the SSN has TC971 AC136 or AC137 on the tax module, the screen will indicate it as a QC or FS case.

  4. Amended return information for this return are listed under the change dates label. Users can enter requests into entry fields in this part of the screen to enter new amend return, or view / modify prior amend return information.

    1. To add a amended return, enter an 'A' in the first input field. A date field is available for the input of the amended return received date field. This date is automatically populated by the command code if the latest amended return date is available. Otherwise, 'YYYYMMDD' is displayed.

    2. If any prior amended return information was entered for this return (up to 4 with the latest first), they would be listed below the first input field. The amended return received date and category code are listed for each record. Enter a 'V' on the desired record to display the validation result screen for previously entered records. Command code DDBCK also allow a user to enter a 'D' or a 'C' on the last entered record to delete or change the last entered record

2.4.58.4  (01-01-2007)
Command Code DDBCK Return Update Screen

  1. The DDBCK Return Update Screen is displayed when an add request or change request is entered from the summary screen. The input fields and fields that can be changed are highlighted on the screen.

  2. The following fields should be entered as needed when entering changes:

    1. If a SSN is added, or to correct invalid SSN/Name control, enter it into the SSN/AMEND & N/C field

    2. To add a credit claimed, enter an ‘A’ under the EIC, Exemption/DEPD, CTC, CCC, EDCR, or ADPT CR field

    3. To delete a credit previously claimed, enter a ‘D’ under the EIC, Exemption/DEPD, CTC, CCC, EDCR, or ADPT CR field

    4. The additional EIC is claimed on the 1040X, enter it in the EIC field

  3. The following input fields are required when entering changes:

    1. Filing status amended

    2. Category code (EICX, EICC, EICP or EICN)

    3. Claim amount (refund amount on 1040X)

    4. Schedule C indicator ('Y' if the 1040X has a schedule C, otherwise 'N'). If 'Y' is entered, a subsequent second screen will be displayed for entering additional information from the schedule C.

  4. Once the changes are transmitted, the command code will validate the entered information. Should the age of an EITC qualifying child be over 19, it will ask whether the QC is a student or disabled and waits for user to reply before continuing.

2.4.58.5  (01-01-2007)
Command Code DDBCK Validation Result Screen

  1. The DDBCK validation result screen is displayed after the changes entered in the DDBCK return update screen have been validated. The results for each of the following items are displayed for each child that was added or changed: TIN/Name control check, date of birth/date of death check, DUPTIN check and FCR check. Items that failed validation are displayed in red.

  2. List of rules broken are displayed. The status of the validation is also displayed (Validation completed, validation failed, etc.) On DDBCV, validation results are displayed for research purposes only, and the data will not be saved, nor will it send case to exam.

  3. If the validation passes, and the case is not selected for exam or classification, DDBCK updates DUPTIN/DUPOL to reflect any changed that were entered. If the TIN or name control entered failed validation, DUPTIN will not be updated, Instead, the command code will send a prompt "PROCESS UPDATES (Y/N)?" and waits for the user to respond before continuing. If the validation error is caused by data entry error, the fields can be corrected. When corrections are made and retransmitted, DDBCK will validate the input again from the beginning. To go ahead and update DUPTIN anyway using the incorrect TIN (in case the TIN / name control cannot be corrected), enter a ‘Y’ in the response field and transmit.

  4. DDBCK also makes a final determination for the case based on the validation results. The message near the bottom of the DDBCK validation result screen will tell the user on how to proceed with the case. Depending on the message, the case will either be

    1. OK to input ADJ54

    2. Sent to exam (DDBCK SELECTED, REROUTE TO EITC)

    3. Sent to classification (SEND AS CAT A)

    If the case does not meet exam criteria (OK TO INPUT ADJ54), the adjustment should be processed using normal procedures. If the case meets exam criteria and selected, DDBCK automatically generates the AIMS opening request (via TC424) for the next posting cycle.

  5. Users can hit transmit from the first page of the validation result screen to go to a second page. The second page displays the money amounts entered from the return update screen plus additional details on which rules that fired and who they fired for.

2.4.58.6  (01-01-2007)
Command Code DDBCS Selection Setup Screen

  1. The DDBCS selection setup screen is used by headquarters to monitor and modify the work plans, day to day, week to week and site by site.

  2. Business rules that apply are as follows:

    1. Route additional cases to any other campus that still has capacity (choose the one with the lowest inventory) if the return does not have Schedule C issue.

    2. If the return has Schedule C issues, route additional cases to another SBSE campus that still has capacity.
