ME53N — Display Purchase Requisition
ME53N is the display-only transaction for a purchase requisition, showing the Enjoy-style single-screen layout with item overview, account assignment, and release status tabs. It is used to check requisition data, release status, and source-of-supply assignment without risk of accidental change, which is why it is the safe default when a requisition just needs to be read, not edited.
This page covers ME53N, the display transaction for purchase requisitions, and focuses on why requisitions get stuck in the buyer's queue or fail to convert into a purchase order. It walks through the release status logic, account assignment checks, and the join needed to prove a discrepancy in the underlying tables.

Purpose
ME53N opens a purchase requisition in display mode using the same Enjoy screen framework as ME52N and ME51N, with a header area, an item overview grid, and a lower detail area split into tabs for material data, quantities/dates, valuation, account assignment, source of supply, and status. The one structural fact that explains most confusion: ME53N shares its screen layout, personalization settings, and even its authorization object family with the create and change transactions, so a user who cannot see a tab or a field in ME53N usually has the same restriction in ME52N, and the fix is rarely transaction-specific. Because it is display-only, it is the transaction to hand to anyone auditing a requisition, checking why a purchase order was not generated, or confirming release status without any risk of triggering a change document.
When it is used
ME53N sits between requisition creation (manual via ME51N, or automatic from MRP, a maintenance order, a project, or a sales order) and conversion into a purchase order or outline agreement item. A buyer opens ME53N to confirm a requisition has cleared release strategy before attempting conversion, a requester uses it to check whether their request has been actioned, and a controller uses it to verify account assignment or cost center before financial postings occur. In practice, consultants reach for ME53N during incident triage far more than during normal processing: it is the fastest way to see release status, deletion indicator, and source-of-supply assignment in one screen before deciding whether the problem lives in the requisition itself or downstream in the purchase order or in MRP.
How to use it in practice
- Open ME53N and enter the requisition number directly if known, or use the 'Other Purchase Requisition' menu to search by material, plant, requester, or creation date range
- Check the header status area first for the overall release indicator and any deletion or blocking flag
- Move to the item overview and confirm plant, storage location, and short text match expectation for the item in question
- Open the account assignment tab if the item is account-assigned and verify cost center, WBS element, or order number against the source document
- Open the source of supply tab to see whether a fixed vendor, contract, or info record is proposed, and whether that proposal was accepted or overridden
- Check the release strategy tab if release is required, reading the sequence of approval codes and which ones are still outstanding
- Use the document flow or purchase order tracking button to jump to any PO already created against the requisition
Key data objects
- EBAN - purchase requisition item data: material, plant, quantities, delivery date, requisitioner, release indicator, fixed vendor, deletion indicator
- EBKN - account assignment lines for the requisition item: cost center, WBS element, order number, distribution percentages
- CDHDR and CDPOS - change documents recording who changed release status, quantity, or deletion flag and when
- T161 and related customizing tables - document type and item category control that determine which fields and tabs are active for a given requisition type
How to prove it in the data
In SE16N pull EBAN filtered on BANFN for the requisition number and check the FRGKZ (release indicator) and LOEKZ (deletion indicator) fields directly rather than trusting the screen icon, since the icon can be misread when multiple release codes are involved. Join EBAN to EBKN on BANFN and BNFPO to compare account assignment lines against the source cost object. To confirm whether a purchase order was ever created, filter table EKPO on BANFN and BNFPO and check whether any line references the requisition; an empty result with a release indicator showing complete means the requisition is releasable but was never converted, which points at a buyer workload or MRP follow-up issue rather than a data issue.
ECC vs S/4HANA
ME53N continues to function unchanged on S/4HANA as the classic GUI display transaction for purchase requisitions, and remains the transaction most functional consultants use for troubleshooting because it exposes tabs and technical fields not always surfaced in the Fiori equivalent. S/4HANA adds Fiori apps for managing and approving purchase requisitions, including a My Purchase Requisitions type app for requesters and approval worklist apps for approvers, but these are workflow-oriented views rather than full replacements for the detailed tab structure in ME53N.
Common pitfalls and how to diagnose them
- Release status misread: the requisition shows as blocked in ME53N but the release strategy has actually completed at header level while one item-level code is still open; check EBAN-FRGKZ and the individual release codes in the release strategy tab rather than assuming header status applies uniformly to every item
- Requisition not visible to the buyer: purchasing group or plant assignment on the requisition does not match the buyer's authorization scope in the purchasing group release worklist, so the requisition exists and is fully released but never surfaces in ME57 or ME58; confirm the purchasing group field on the item and compare it to the user's authorized groups
- Account assignment locked or wrong: a change to cost center or WBS element after the requisition was created does not automatically propagate, and EBKN can carry a reference to an object that has since been blocked or closed, causing conversion to fail with an account assignment error that looks unrelated to the requisition itself
- Source of supply mismatch: a fixed source assigned on the requisition (contract or info record) has expired or been deleted, so ME53N still shows the old assignment but conversion attempts fail; check the validity dates on the referenced outline agreement or info record, not the requisition
- Deletion indicator confusion: an item flagged for deletion still displays normally in ME53N and can be mistaken for an active open requisition; the deletion flag is easy to miss on the item overview grid and only shows clearly in the EBAN table check
- Display looks stale after a known change: ME53N was left open in another session or the change was made in a background job; always re-open the transaction fresh rather than relying on a cached screen before escalating a data discrepancy
Whose problem this is
This is a functional MM/purchasing issue in nearly every case: release strategy configuration, purchasing group assignment, and account assignment logic are all customizing and master data, not code. Basis involvement is only relevant if authorization objects are misassigned at the role level. A good handover includes the requisition number, the exact tab and field showing the unexpected value, and the EBAN release indicator read directly from the table rather than the screen icon.
