Gets the call stack from where the last error occurred.

String := GETLASTERRORCALLSTACK

Property Value/Return Value

Type: Text

A text string that contains the call stack from where the error occurred.

The format of the string is:

<codeunit name>(Codeunit <number>).<function name> line <line number>\[<calling codeunit name>(Codeunit <number>).<calling function name> line <line number>\...]

The string cannot exceed the maximum string length that is specified in Microsoft Dynamics NAV, which is 1,024 characters.

If no error has occurred, then the function returns an empty string.

Remarks

For some errors, such as divide by zero errors and overflow errors, GETLASTERRORCALLSTACK does not return every call in the stack. To get the complete call stack for these types of errors, use the debugger and specify that you want to break on errors. On the Debugger page, in the Call Stack FactBox, you can view all the function calls that led to the error. For more information, see How to: Break on Errors.

Example

In this example, an error occurs in codeunit 50003. The text of the MESSAGE includes a call to the GETLASTERRORCALLSTACK function.

 Copy Code
// Codeunit 50001, TestErrors1
// OnRun trigger
ERROR('Some error message')
// Codeunit 50002, TestErrors2
// OnRun trigger
CLEARLASTERROR;
IF NOT Codeunit.RUN(50001) THEN
  MESSAGE('The call stack for the last error is:\' + GETLASTERRORCALLSTACK);

When you run codeunit 50002, the message window displays the following:

The call stack for the last error is:

TestErrors1(CodeUnit 50001).OnRun(Trigger) line 1

TestErrors2(CodeUnit 50002).OnRun(Trigger) line 2
