How To Fix MCEX151 - Entries for application &1 still exist in the extraction queue ->

SAP Error Message - Details

• Message type: E = Error

• Message class: MCEX - Extraction Interface LIS/BW

• Message number: 151

• Message text: Entries for application &1 still exist in the extraction queue ->

What causes this issue?

Changing extraction structure &V2& for application &V1& is forbidden,
because there are entries that have not yet been processed into an
extraction queue for application &V1& for at least one client.
If an extraction structure is changed to the entries that are still
open in an extraction queue, then these are no longer able to be read
and can cause terminations with the collective update.

How to fix this error?

Start the collective update using the function "Job Control" in the
<DS:TRAN.LBWE>Logistics Extraction Structures Customizing Cockpit</>.
To get an overview of the logistics extraction queues, see the
<DS:TRAN.LBWQ>Logistics Queue Overview</>.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message MCEX151 - Entries for application &1 still exist in the extraction queue -> ?

  The SAP error message MCEX151 indicates that there are still entries in the extraction queue for a specific application (denoted by &1). This typically occurs in the context of data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP ECC (Enterprise Central Component) systems.
  Cause:
  The error usually arises when:
  
  Incomplete Data Extraction: There are still records in the extraction queue that have not been processed or have failed during the extraction process.
  Data Locking Issues: The data might be locked due to ongoing processes or transactions that are preventing the extraction from completing.
  Configuration Issues: There may be configuration problems in the data source or the extraction setup that are causing the extraction to not complete successfully.
  
  Solution:
  To resolve the MCEX151 error, you can follow these steps:
  
  
  Check the Extraction Queue:
  
  Use transaction code RSA7 to check the extraction queue for the application. This will show you the entries that are still pending.
  If there are entries that are stuck, you may need to analyze why they are not being processed.
  
  
  
  Process or Delete Stuck Entries:
  
  If you identify entries that are stuck, you can either process them manually or delete them if they are no longer needed.
  You can use transaction SMQ1 (for outbound queues) to monitor and manage the queues.
  
  
  
  Check for Data Locks:
  
  Ensure that there are no ongoing processes that are locking the data. You can use transaction SM12 to check for locks and release them if necessary.
  
  
  
  Review Configuration:
  
  Verify the configuration of the data source and ensure that it is set up correctly. Check for any inconsistencies in the settings that might be causing the extraction to fail.
  
  
  
  Monitor Background Jobs:
  
  Check if there are any background jobs that are supposed to process the extraction and ensure they are running without errors. Use transaction SM37 to monitor job statuses.
  
  
  
  Re-run the Extraction:
  
  After addressing the issues, you can re-run the extraction process to see if the error persists.
