T code to record to approve vendor invoice in workflow
B
Correct answer
Explanation
SBWP is the SAP transaction code for SAP Business Workplace, which is the workflow inbox where approvers review and approve vendor invoices submitted through workflow. F110 is the payment proposal/program, not the approval inbox. SPWB and OB08 are unrelated to invoice workflow (SPWB is not a standard T-code, OB08 is for exchange rate maintenance).
