good day sap experts
2- and transaction ( ME23N - Display Purchase Order ) to check PO's details for each vendor individually ( such as balance remaining and expiry date ) ,
I'm checking Vendor's status ( active or blocked ) and other details regularly through SAP Transaction ( MK03 - Display vendor (Purchasing) ,
Vendor blocked report you can get it with t.code MKVZ but vendor active or inactive- you need to have your business concept with your design. Decide which vendor is inactive with a concept for example those have latest transactions till last 2years from today date else all are active. You can design your own concept with newly design t.code where no transactions such as no PO creation and no invoice creation along with no payment done for last two years for vendors/suppliers for inactive!
