Hi. Yes - you can modify a Purchase Req created by MRP/PMRP. The following is information on history logging -
In IFS Cloud, tracking and viewing changes made to a Purchase Requisition (PR) can be handled through several built-in mechanisms depending on whether you are looking for field-level database audit logs, authorization history, or application status tracking.
1. System History Log (Database Audit Trail)
IFS Cloud includes a central History Log framework that captures row- and field-level changes (Inserts, Updates, Deletes) made to Purchase Requisitions. History Log
2. Authorization History
If your organization uses Purchase Requisition Authorization Rules, changes to approval steps and status transitions are recorded separately:
-
Authorization Progress: Tracks each authorization step, required authorizer/group, actual authorizer, and authorization date.
-
How to View: Open the Purchase Requisition and view the Authorization tab or navigate to Purchase Requisition Authorization pages to inspect who approved or rejected the requisition lines and when.
3. Order Lifecycle & Status Progression
Changes in the lifecycle of a Purchase Requisition line are logged as part of operational pegging and status history:
-
Status Changes: Tracks state transitions such as Planned → Released → Partially Authorized → Authorized → Request Created / PO Created.
-
Connected Objects: If a PR line is converted into a Request for Order Quotation (RFQ) or Purchase Order (PO), IFS Cloud maintains pegging references linking the PR line to the resulting PO or RFQ. Sourcing Manager - Implementation Guide
4. Custom Event Logging (Optional)
If specific business fields require immediate notifications or tailored audit trails (e.g., tracking whenever a PR line quantity is decreased or canceled after release):
I hope this helps. Thanks! Jane
