AX / Dynamics 365 For Finance and Operations blog

In Dynamics 365 Finance and Operations (D365FO), the InfoLog is a key component used to display messages such as errors, warnings, and information logs. However, when working with batch jobs or processes that execute within the SysOperation Framework, messages in the InfoLog may be cleared or lost between executions.

This article demonstrates how to save and restore the InfoLog using the infolog.infologData() method in X++. This approach ensures that messages are preserved even when InfoLog is reset.

To address this issue, you can capture the InfoLog messages before execution and restore them afterward.

InfologData infologData;

void saveInfolog()
{
    // Logging messages
    error("Something awful happened");
    error("Something terrible occurred");
    setprefix("Scary");
    warning("Mouse detected");
    
    // Saving InfoLog data
    infologData = infolog.infologData();
    infolog.clear(0);  // Clear InfoLog after saving
}

void restoreInfolog()
{
    // Restoring InfoLog messages
    infolog.import(infologData);
}

// Execute Save and Restore
saveInfolog();
restoreInfolog();

// Display restored InfoLog
infolog.view();
info(Info::infoCon2str(infologData));

When to Use This Approach

• In Batch Jobs: When running batch processes that clear InfoLog.
• With Data Management (DMF) Imports: To preserve messages across executions.
• In Long-Running Operations: When multiple steps could potentially overwrite InfoLog messages.
• Debugging: To capture logs and analyze them later.
