Supplier Cost not transferred to Projects Costing

Good Day,

We are currently launching Project Costing and are conducting exploratory testing. I have created a project supplier invoice tagging it with POET details.  I can see the expenditure details in Project Status Inquiry (PSI) but not the expenditure amounts after generated process PRC: Interface Supplier Costs and AUD: Supplier Costs Interface Audit are not being displays nor transferred. I am not sure what to do?
