To Debug the Customization Code

The Code Editor does not provide facilities you can use to debug a code item of a customization project. We recommend that you use Microsoft Visual Studio to develop and debug any source code in customization projects. To start debugging using in Visual Studio, you need to perform the following steps, which are described in greater detail below:

  1. Install Acumatica Debugger Tools.
  2. Configure the web.config file for your Acumatica ERP instance.
  3. Perform the debugging.

Install Acumatica Debugger Tools

The MYOB debugger tools are PDB files located in the Bin folder of the MYOB Advanced site folder.

The PDB files are copied to the Acumatica ERP/Files/Bin folder during the installation process if the Install Debugger Tools option is selected. If you haven't selected this option during installation, you should remove MYOB Advanced and install it again with the Install Debugger Tools option selected. For details, see To Install the Acumatica ERP Tools.

Every time you install or upgrade any MYOB instance, the MYOB Advanced Configuration Wizard copies data from the Acumatica ERP/Files/Bin folder to replace instance files. These files are not copied to any instance automatically. To be able to debug MYOB, you must have them in every instance that you need to debug.

To distribute PDB files, you can do one of the following:

  • Install a new instance
  • Upgrade an existing instance
  • Copy files manually from Acumatica ERP/Files/Bin

If you want to copy files manually, note that the most important files are the following:

  • PX.Data.pdb (PDB for PX.Data.dll), which contains the platform core code
  • PX.Objects.pdb (PDB for PX.Objects.dll), which contains the MYOB Advanced business logic
Note: DLLs and PDBs should be from the same version of MYOB Advanced, so you cannot copy PDB from 2020 R2 Update 8 to 2020 R2 update 9 and use it for debugging.

Prepare the web.config File for your Acumatica ERP instance

When the installation is finished and the instance is ready, you have to specify the debug option by doing the following:

  • In the MYOB Advanced folder, open in a text editor the web.config file located in the root folder of the your instance.
  • In the<system.web> tag of the file, locate the <compilation> element.
  • Set the debug attribute of the element to true as follows.
    <compilation debug="true" ...>
    Note: See Debug mode in ASP.NET applications for details.

Perform the Debugging

To configure VS to debug source code of MYOB Advanced code, select Tools > Options > Debugging > General, and clear the Enable Just My Code check box.

To specify the path for PDB files, select Tools > Options > Debugging > Symbols, and add a path to your files (which is typically C:\\Program files\Acumatica ERP\Files\Bin).

To browse an existing Code item in Visual Studio, perform the following instructions:
  1. Publish the customization project, as described in Publishing Customization Projects.
  2. Make sure your instance of MYOB Advanced is running by opening any page of the instance in a browser.
  3. Launch Visual Studio as an administrator.
  4. To open the website of your instance of MYOB Advanced in Visual Studio, on the main menu, click File > Open > Web Site, and select the website folder in the Open Web Site dialog box, which opens.
  5. In the Solution Explorer of Visual Studio, expand the App_RuntimeCode website folder, and double-click the file of the Code item to open it.

To debug customization code that has been added from the user interface, see To Move a Code Item to the Extension Library.

To start debugging an existing Code item in Visual Studio, do the following:

  1. In the item source code, set a breakpoint on the line of the code where you need to stop the process for debugging.
  2. On the main menu, click Debug > Attach to Process, and in the Attach to Process dialog box, which opens, select the w3wp.exe process in the list of Available Processes.
    Note: In the dialog box, ensure that the Show processes from all users check box is selected. If the check box is cleared, the list will not display the w3wp.exe process record.
  3. In the browser, open the form of MYOB Advanced whose business logic code you want to debug.
  4. In the browser, run an operation that invokes the fragment of the code that contains the breakpoint.

The process will be stopped at the breakpoint, and you can debug the code in Visual Studio.
