Suppress SLA account generation upon Invoice Validation

I am configuring SLA for a federal client using budgetary control.We are currently using Two JLDs for Event Class = Invoices.One for the Budgetary entries and one for the Proprietary entries.The Budgetary JLD has Budgetary Control enabled, therefore, fires upon Invoice Validation.What is required to suppress accounting from this Budgetary Control JLD, and still allow the invoice to validate successfully.As we have situations where only the proprietary entries created by the Proprietary JLD are necessary.In our experience, if invoice validation cannot generate accounting for an invoice, an encumbrance accounting hold is placed.
