Performance issue when validating Account No. / Account Type on General Journal Line pages

Hi Microsoft Support Team,
We are currently experiencing a performance issue in Business Central related to journal entry processing.
Issue Description
When users input or modify values in the following fields:

Account No.
Account Type

on pages where General Journal Line is used as the source table, the system responds very slowly.
Investigation Result
We performed debugging and identified that the delay seems to be related to the Workflow Management codeunit.
Specifically, the following procedure is consuming significant processing time during field validation:
FindWorkflowStepInstanceWithOptionalWorkflowStart
This procedure appears to be triggered repeatedly whenever the Account No. or Account Type fields are validated.
Current Impact

Slow user experience during journal entry input
Significant delay when entering multiple journal lines
Users report lag during daily operations

Additional Information

Environment: SaaS
Business Central Version: 27.5
Workflow Enabled: Yes
Customization related to journal/workflow: No (we already uninstall all extension)

Could you please help advise:

Whether this is a known issue
If there are any hotfixes or performance recommendations
Whether this behavior is expected by design

Thank you for your support.

HI,

Your investigation points to the right place. FindWorkflowStepInstanceWithOptionalWorkflowStart appears to be triggered during field validation, to check if any active workflow step should react to that field change. On General Journal Line this seems to fire per field per line, so entering many lines multiplies it and the lag becomes very visible.
Few things to check. Even if you uninstalled custom extensions, the standard Workflow still runs if any enabled workflow listens on journal or general events. Open the Workflows page and check for an enabled workflow with an entry point related to general journal or approval — disable the ones you do not actually use, because the subscribers stay active as long as a workflow is enabled.

Best test is to run the same journal in a clean sandbox with all workflows disabled. If it is fast there, it confirms the workflow part is the cause, not the journal itself. Since this is SaaS 27.5, capture the slow operation in Application Insights and open a Microsoft support case with that telemetry, so they confirm if it is by design or a regression.

Hope this help, Best regards.
