Invoice Plan on ERP extended classic PO?

Question

We are using ECS.  The ERP PO is display only as standard.  Can I still add an invoicing plan in the ERP system to this display only purchase order?

Hi Paul
Please refer to these details regarding Invoice Plans in SAP
1) Maintain settings in Customizing for purchasing (for example, invoicing plan type, date categories, date descriptions, and date sequence proposals). The related path is IMG ---> Material Management ---> Purchasing ---> Purchase Order ---> Invoicing Plan ...... 
2) The Purchasing document with FO Document Type (Framework Order) must be used. This document type requires that a validity period be entered in the PO header. This specification is adopted in the invoicing plan, provided that this has been predefined in Customizing for the relevant invoicing plan type. 
3) The purchase order item must have an account assignment and Logistics Invoice Verification must be used. 
4) The vendor must have agreed to use the automatic invoice creation facility (since we will use automatic settlement to create the invoice). In this case, the 'AutoEvalGRSetmtDel.' indicator must be flagged in the vendor master record. 
5) Once Purchase Order is created with order type FO, ensure that the indicators for GR/IR control have been set correctly on the item detail screen.
6) The Goods Receipt indicator may only be set in combination with the Goods Receipt Non-Valuated indicator. The Invoice indicator must be set.
7) For the automatic creation of invoices, the ERS (Evaluated Receipt Settlement) indicator must be also set. A further prerequisite for automatic settlement is that a tax code must be entered in the purchase order.
