Deleted PO is being sent to vendor.

Hi Experts,

I need your help for one issue in our project.

We have work flow configured in the PO level. Once the work flow has been rejected from the approver for the PO and user delete the line number of the Po after that, out put is getting triggered and po has been transmitted to supplier.

Supplier sending those goods for those deleted POs which is not required for the business.

It is impacting the stock level and financial too.

Could you please suggest how to avoid this situation.

Best regards

Diptiman
