Error in ‘Amount in Words’ during Check Report Customization in Business Central? Here’s what you can do!

Error in ‘Amount in Words’ during Check Report Customization in Business Central? Here’s what you can do!


In Business Central, the existing reports cannot be modified. Thus, for modifications in the report, the existing report is to converted to text using Text-To-Al and then modifications are to performed. But in case of Check Report(10401) it doesn’t work giving error ‘Index out of bounds!’.


Microsoft Dynamics Business Central (Online)


When modifying the Check Report in Business Central, the only approach available is converting existing Check Report 10401 to Text and then using Text-To-Al.Which gives the error ‘Index-Out-of-Bounds!’. Thus for a workaround I used the code from

Although this algorithm works perfectly on NAV and Business Central On Premise, it returns the same error on Business Central Online. As assumed, it was because of the recursion used.

So, here is the non-recursive algorithm that works perfectly fine up to 8 digits characteristics and 2 digits of mantissa.

List of variables:

Units[10], Tens[20], Expos[30] are arrays with respective dimensions.

Initialization of Variables:

While the updates are still getting generated on this issue, it is far from being conclusive to reach out to the expected results.

As per our cordial discussions with Microsoft, the existing  report objects on On-Premise versions such as NAV and Business Central On Premise are not 100% compatible with Business Central Online  which are converted using Text-To-Al tool.

In the next blog, I’ll write about update for the same.


Import and Export using Excel Buffers


Using XMLPort to do the Import and Export using CSV or Tab Delimited .xls can be inconvenient at times. For example when the field value contains a COMMA (First Name, Last Name) or if there are QUOTES(“”) added by Excel when saving the data. Thus the best way I found was using Excel Buffer.


  1. Microsoft Dynamics NAV 2013 R2 and above
  2. Microsoft Office 2010 and above


Excel Buffer Table(370) is a table that stores the data from each cell as Row,Column, TextValue, Formula and other fields in a single record. So if Excel Sheet contains 5×5 grid i.e 5 rows and 5columns then the whole data is stored in the form 10 records in Excel Buffer. The Excel sheets can have various types of visual formatting such as Bold, Italic, Underline, Font Color, Background Colour etc.


1. Exporting using Excel Buffer:

Export Excel Buffer Sample Code

                 Export Excel Buffer Sample Code

i. Var ExcelBufferTable – Type Record -ID 370

ii. ExcelBufferTable.AddColumn(<Value:Text>,<IsFormula:Boolean>,<CommentText:Text>,<IsBold:Boolean>,<IsItalics:Boolean>,<IsUnderlined:Boolean>,<NumFormat:Text>,<CellType:Option>) – adds a colum of required type.

iii. ExcelBufferTable.NewRow – adds a new row to the sheet.

iv. ExcelBufferTable.CreateBookAndOpenExcel(<FileName:Text>,<SheetName:Text>,<ReportHeader:Text>,<CompanyName:Text>,<User:Text>) – creates the Excel Sheet and the Excel Program.

 2. Importing using Excel Buffer:


Import1 Excel Buffer
















i. FileMgmt.UploadFile(<WindowTitle:Text>,<FileExtension:Text>) – Uploaded the file using File Management codeunit function

ii. ExcelBufferTable.OpenBook(<Filename:Text>,<SheetName:Text>) – Open the Excel Sheet passed as Excel File(.xlsx) and read the sheet with name ‘Gift Cards’.

iii. Read the sheet using ExcelBuffer

iv. Count total Rows and Columns in the Excel sheet

v. GetValueAtCell(<RowNo:Integer>,<ColumnNo:Integer>) – Read each cell using function GetValueAtCell


Thus, this is how I’ve implemented Excel Buffer for Importing and Exporting Excel Sheets. The import export was performed based on the Action Buttons as required and no special objects were created. Thanks for reading and stay in touch 🙂

Setting up a custom Positive Pay Export for Key Bank in NAV 2017


What is Positive Pay Export and Why its used??
Positive Pay Export is a file that is given to the bank to verify the Cheques that have been printed.
Whenever the company wants to issue any payment to Customer or a Vendor, it is done with the help of Payment Journals. After creation of Payment Journal lines, the check is printed through a Report. 

After the creation of the Check in the Bank Account there is an action called as PositivePayExport. This file is a text file and contains the information related to the Cheques printed and it is given to the bank.
Every bank has their format which is used to automatically verify the Cheques that are being issued.


1. Creating a Bank Account: To issue the cheque setting up Bank Account is mandatory

  1. Setting up the Data Exchange Definitions: Data Exchange Definition is used to setup the format for Positive Pay Export.

    iii. Creating Column Definitions: Column Definition is the sequence in which the data is to be generated as per the format.

    iv. Creating a Line Definitions:
    Line Definitions are used to map the System Fields to the fields in the column defintions. In the Line Definition there are transformation rules that are used to modify the data that is exported into the format.

    v. Create a Line Definition and Select Field Mapping:

    vi. Transformation Rules:There are some predefined Transformation Rules as well as new transformation Rules can be created. I’ve created the following transformation rules.
