: Trying to cancel a Purchase Order (PO) that is already in a "Closed" or "In Process" state.

To resolve this, you must move past the UI error and find the Stack Trace.

The article will be written in a helpful, informative tone. Oracle Purchasing error can be a frustrating roadblock when you're trying to manage purchase orders, blanket releases, or requisitions. Understanding its cause and resolution is crucial for maintaining a smooth procurement workflow.

: Check that the line_location_id matches between the purchase order and the original request lines.

Locate the folder where the portable application is stored. Look for a folder named Temp , Cache , or Data . Delete the contents within that folder (ensure the app is closed first). 5. Check Network Connection (If Applicable)

Copy the code combination ID (CCID) from the PO distributions tab.

The software must write temporary PDF or XML files to the host machine. If the user account lacks write permissions to the Temp directory, the action fails.

If the front-end data looks correct, backend data corruption may be the issue. Have your database administrator run standard Oracle diagnostics (like po_headers_all or po_lines_all data dumps) to verify that line_location_id values match across your purchase order and requisition lines.

The root cause of this error message is a state conflict within the Oracle Purchasing module. The application stops the process because the action you want to take (such as canceling, approving, or forwarding) does not match the actual lifecycle status of the document. The most common reasons for this conflict include:

Attempt to generate or submit the document again. This grants the software permission to access local system paths and temporary folders. 3. Clear the Temporary Cache

If you are running mobile setups, portable database environments, or standard desktop terminal interfaces, resolving this error requires understanding the technical incompatibilities within Oracle EBS. What Causes the APP-PO-14160 Error?

The document identifier follows the naming convention typically used in Oracle Application Express (APEX) , specifically regarding the APEX Print (APPO) engine or APEX Listener operations. The error "Document action not completed successfully" is a generic catch-all handler indicating that the print engine failed to generate or process the requested document (PDF, Excel, or Word).

: The PO might be linked to an internal requisition, which can restrict certain manual actions if the requisition status hasn't transitioned correctly.

: Discrepancies between the PO line locations and the original request lines (e.g., line_location_id mismatches). Troubleshooting & Fixes

Ensure that the card reader drivers and cryptographic middleware on the host machine are updated to the latest versions.

If the application relies on a network path (like an SAP repository or shared drive), a temporary drop in connection will trigger this error.

If the error only triggers with certain documents, the file itself might be the culprit.

What are you using (Windows, Android, iOS)? Which program are you using when the error pops up? Are you trying to print, save, or email the document?

The generic error message masks the actual exception. To solve this, we must dissect the potential failure points in the "Document Action" pipeline:
