This is my revised code from my original question Check Accounting Journal for Errors

I was able to use the information provided in the answers to that question to get my code cleaned up removing duplication and utilizing better coding practices. I want to make sure I didn't miss anything and would appreciate a final review to ensure that there isn't any remaining problems that need attention.

The name of Disable isn't really what it's doing. More you're turning off application properties. Same for Enable.

    On Error Resume Next
    Sheet2.Unprotect "secret"
    ThisWorkbook.Unprotect "secret"

Seems like maybe you'd check for protection instead of just eating errors up.

    On Error Resume Next
    Sheet2.Protect Password:="secret", AllowFormattingColumns:=True, _ 
    ThisWorkbook.Protect Password:="secret", Structure:=True, Windows:=False

Here we're eating errors again, what could go wrong? And why wouldn't you want to know it went wrong?

On these processes

Private Sub ConvertDebitsAndCreditsToUppercase(debitCreditRng As Range)
Private Sub NoNegativeAmounts(amountRng As Range)

you're passing a range to alter the contents of the range at the range. It would be faster to take the values off the sheet change them and then put them back. You could also get rid of those EVALUATEs.

In your LastRow function you've hardcoded it to Sheet2. Why not allow an argument and use that?

Private Function LastRow(ByVal targetSheet As Worksheet) As Long
    LastRow = targetSheet.Cells(targetSheet.Rows.count, 4).End(xlUp).Row
End Function

Speaking of arguments, you're pretty much sending all your arguments ByRef. You want to use ByVal whenever you can. Quoting RubberDuck -

Parameters are passed by reference unless specified otherwise, which can be confusing and bug-prone. Prefer passing parameters by value and specify ByRef explicitly when passing parameters by reference.


A parameter that is passed by reference and isn't assigned a new value/reference, could be passed by value instead.

Speaking of doing things explicitly, every single time you use range or cell without giving it a sheet, it's implicitly using ActiveSheet. Try to always be as explicit as possible.

Variable names - give your variables meaningful names. What's a rng or a glRng? Is that generalLedgerAccounts instead? Also try to follow standard VBA naming conventions have camelCase for local variables and PascalCase for other variables and names.


I see a few strings being used

  • "GL_Account_Number" - 3
  • "Profit_Center" - 2
  • "Amount_in_Doc_Currency" - 3
  • "DR_CR__Indicator" - 2
  • "Cost_Center" - 2

With things like these, you might want to put them into a variable so that you only have to change the variable if the names ever change. And since they are static most of the time, you can make them constant variables:

Const PCENTER As String = "Profit_Center"
Const CCENTER As String = "Cost Center"
Const GLAN As String = "GL_Account_Number"

Put these at the top of the module and all your functions have access to them.
