This happens when the Expense Category is not configured in the Emist Configuration Application form. The system requires proper expense category mapping to calculate trip budgets and validate advances correctly.

If the mapping is missing, the Trip Expense Budget will not be calculated, and advances may incorrectly appear as pending approval even if they are within the budget.

Resolution:

Ensure that the relevant Expense Categories are configured and correctly mapped in the Emist Configuration Application form. Once the mapping is set up, the system will calculate budgets accurately and update the approval status of advances automatically.
