What to Do If You Generated a Consolidated e-Invoice Early but Still Have More Sales?

Overview:
If a consolidated e-Invoice has already been generated but additional transactions are recorded within the same month before submission, you can use Re-Generate Data to update the consolidated e-Invoice to include the latest transactions.

Consolidated e-Invoices are prepared on a monthly basis and must be submitted by the 7th day of the following month (e.g., December 2025 → submit by 7 January 2026).

Use Re-Generate Data to update an unsubmitted consolidated e-Invoice and include any additional transactions recorded within the same month before the submission deadline.

Scenario:

Beans Retail Sdn Bhd records daily cash sales in December 2025. To streamline month-end closing, the company generated a consolidated e-Invoice on 28 December 2025, covering cash sales from 1–28 December 2025.

• Consolidated e-Invoice reference: CEI2512/009
• Included transactions: CS1-COFFEE, CS2-COFFEE

At this stage, CEI2512/009 is ready for submission, subject to any additional cash sales recorded before the statutory submission deadline of 7 January 2026.

On 29 December 2025, two additional cash sales were recorded: CS3-COFFEE, CS4-COFFEE 

Steps to update CEI2512/009:

1. Open CEI2512/009 and click Edit

2. Select Re-Generate Data

After regeneration, CS3-COFFEE and CS4-COFFEE will be added to the consolidated e-Invoice together with the earlier transactions. You can then proceed to submit CEI2512/009 and remain compliant. 

Re-Generate Data is used for unsubmitted consolidated e-Invoices. Once submitted, updates require a different compliance process.

Regenerate Data in Consolidated e-Invoice — Q&A 

Q1: When should I use the “Re-Generate Data” function in a consolidated e-Invoice?

Use Re-Generate Data when a consolidated e-Invoice has already been generated, but new eligible transactions are recorded within the same month before submission.

This ensures all transactions for that month are included before the consolidated e-Invoice is submitted.

Q2: Why is this function needed?

Consolidated e-Invoices are often generated before month-end to support internal reconciliation and closing.
If additional transactions occur after the consolidated e-Invoice is generated — but before submission — Re-Generate Data allows you to update the same consolidated e-Invoice instead of creating a new one.

Q3: What happens when I click “Re-Generate Data”?

When you select Edit → Re-Generate Data, the system refreshes the consolidated e-Invoice and:

• Retains all previously included transactions

• Adds any newly recorded eligible transactions within the same month/date range

• Keeps the same consolidated e-Invoice reference number (if applicable)

No existing data is removed.

Q4: Does Re-Generate Data overwrite or delete existing transactions in the consolidated e-Invoice?

No.
Re-Generate Data does not delete or replace existing transactions. It only adds newly eligible transactions that were not included previously.

Q5: Can I use Re-Generate Data after the consolidated e-Invoice has been submitted?

No.
Re-Generate Data is intended for unsubmitted consolidated e-Invoices only.

Once a consolidated e-Invoice has been submitted, any changes must follow the applicable cancellation or adjustment process, in accordance with e-Invoicing regulations.

Q6: Is there a deadline for updating a consolidated e-Invoice using Re-Generate Data?

Yes.
Consolidated e-Invoices are prepared on a monthly basis and must be submitted no later than the 7th day of the following month.

Example:

• Transactions in December 2025

• Submission deadline: 7 January 2026

Re-Generate Data can be used any time before submission, as long as the deadline has not passed.

Q7: Can I regenerate data multiple times before submission?

Yes.
You may re-generate data multiple times, as long as the consolidated e-Invoice has not yet been submitted and new eligible transactions exist. 

Q8: What types of transactions are included when regenerating data?

The system includes all eligible transactions for the selected month/date range, based on the consolidated e-Invoice criteria (for example, cash sales).

Transactions already submitted in another consolidated e-Invoice or outside the date range will not be included. 

Q9: Will the consolidated e-Invoice reference number change after regeneration?

Typically, the consolidated e-Invoice reference number remains the same, as the document is being updated rather than recreated.

If you generate a consolidated e-Invoice early and record more transactions later in the same month, use Re-Generate Data before submission to ensure all transactions are included and remain fully compliant.
