What it is
A material requisition (MR) is the EPC or owner document that defines the equipment to be bought and lists every specification, datasheet, standard and vendor document requirement that applies to the enquiry or order.
Key Takeaways
- The MR is the index to every governing document.
- Check the revision before building the deviation list.
- Quote against the requisition issue named in the enquiry.
Why it matters
A material requisition (MR) is the technical core of an equipment enquiry. It describes the scope of supply, quantities and tag numbers, and lists the referenced documents: project specifications, datasheets, owner standards, drawings, inspection requirements and the vendor documents to be supplied. Requisitions are revised as a project develops, and evaluators check that each quote is based on the correct issue of the requisition and its reference documents. A new revision can change requirements or the referenced documents.
How OdysseyGPT uses it
OdysseyGPT can read the MR and the documents it references together, so each requirement row cites the document it came from. An engineer must still confirm that the right MR revision and referenced documents were loaded.
Evaluation questions
Is the MR the same as a purchase order?
No. The MR defines the technical scope; the purchase order is the commercial contract that refers to it.
Where are vendor document requirements listed?
Usually in a vendor data requirements list attached to or referenced by the MR.
Frequently asked questions
What does a material requisition contain?
Scope of supply, quantities, tags, and the list of applicable specifications, datasheets, standards, inspection requirements and vendor documents.
Why does the MR revision matter?
Each revision can change requirements or referenced documents. Bidding against an old revision is a common source of undeclared deviations.
