If PO budget is not available while raising an invoice:

Navigate to Organizational Workflow and select the PO Items section.

Select the PO mapped to the employee and click on edit icon.

Under the PO Details section, if the Budget Validation option is set to Dates and Budget Mandatory/ Budget only mandatory, a valid balance amount must be available in the PO Available Balance section for that invoice.
