Question details

An Excel VBA macro intended to copy invoice data to an order log is failing to capture all line items, transferring only the first row.

How to Fix Excel VBA Saving Only the First Invoice Item

Product: Excel
Device & OS: not provided
Scenario: Running a VBA script to process an invoice and write its detail lines to an ongoing OrderLog worksheet.
Observed behavior: The macro successfully runs but only saves the first invoice detail line to the order log, ignoring all subsequent items on the invoice.

Before you start

Before modifying your VBA script, ensure you have saved a backup copy of your Excel workbook (.xlsm) to prevent any accidental data loss or macro corruption during testing.

Solution 1Recommended

Correct the VBA Loop Array Assignment

Update your macro script to properly iterate through all invoice lines, ensuring both line-level details and invoice-level headers are assigned inside the loop.

This issue typically occurs because header values or array indices are mistakenly hardcoded to row 1, or the destination row counter is not placed inside the detail loop.

To optimize the process and resolve the issue, the data should be read into an array, manipulated in memory, and then printed out to the OrderLog sheet.

Open the VBA Editor

Press Alt + F11 on your keyboard to open the Visual Basic Editor and locate the module containing your invoice-saving routine.

Read Invoice Range into an Array

Load the entire invoice detail range into a memory array. This allows the script to process the data much faster than reading it cell by cell.

Set Up the Loop

Create a loop (e.g., For i = 1 to UBound(SourceArray)) to iterate through each row. Add a condition to skip any empty detail rows.

Increment the Destination Counter

Inside your loop, increment the destination row counter (e.g., n = n + 1) for every valid invoice item found.

Assign Values Inside the Loop

Assign both the invoice-level values (like Date and Invoice Number) and the line-item details to your destination array using the dynamic variable counter, such as br(n, column).

Write the Array to OrderLog

After the loop finishes, write the fully populated array to the OrderLog sheet in one operation to complete the macro execution.

Best Practice: Always process large sets of data in memory using arrays before writing to a worksheet. This significantly speeds up macro execution times and prevents screen flickering.

Frequently Asked Questions

Why does my VBA macro overwrite the first row repeatedly?

This happens when the row counter variable (e.g., 'n') is not properly incremented inside the loop. If the counter does not increase by 1 for each line item, the script will keep writing new data to the same array index or worksheet row.

How do I find the last used row in an Excel sheet using VBA?

You can dynamically find the last used row in a specific column using a command like: LastRow = Cells(Rows.Count, "A").End(xlUp).Row. This prevents the script from looping through thousands of empty cells.

Is it faster to use memory arrays instead of writing directly to cells?

Yes. Reading a worksheet range into a VBA array, processing it in memory, and dumping the final array back to the worksheet is significantly faster and less resource-intensive than iterating over and writing to individual cells one by one.
