SAP Error Message - Details

• Message class: JIT00 - JIT: Messages for JIT Process

• Message number: 456

• Message text: Complete confirmation not possible; select again

The backflush of the call components in repetitive manufacturing or the
stock transfer of the call component has failed for at least one
material.

System Response

No goods movement has been carried out for at least one material.

How to fix this error?

First refresh the list, so that the postings and error messages can be
selected again (asynchronous update).
You can analyse the errors using the messages in the list. Correct the
error and carry out the posting again within the reprocessing list. If
you have already carried out the posting within the 'classic'
repetitive manufacturing or goods movement transactions, you can also
delete entries from the list.
General notes:
Check all settings that are necessary for the repetitive manufacturing
backflush (or stock transfer) (see the relevant documentation). If
problems occur, you are recommended to carry out the backflush in the
foreground as a test, using the relevant repetitive manufacturing
transactions (or goods movements transactions) in order to be able to
detect errors more easily. In addition, the JIT basic data must be
maintained correspondingly (JIT customer, JIT components group type,
JIT material).
In the basic data you must maintain the production info for the call
components to be backflushed. If the material is not to be backflushed
in the sequenced JIT call process, then delete the backflush indicator
in the sequenced JIT call material data (transaction JITL).
It is also possible that you cannot backflush temporarily because of
access conflicts. Please try again later.

• What is the cause and solution for SAP error message JIT00456 - Complete confirmation not possible; select again ?

  The SAP error message JIT00456, which states "Complete confirmation not possible; select again," typically occurs in the context of Just-In-Time (JIT) production processes. This error indicates that the system is unable to process a complete confirmation for a production order or a related operation. Here are some common causes, potential solutions, and related information for this error:
  Causes:
  
  
  Incomplete Data: The production order may not have all the necessary data or prerequisites completed. This could include missing components, unconfirmed operations, or incorrect status of the order.
  
  
  Status Issues: The production order or operation might be in a status that does not allow for complete confirmation. For example, if the order is already confirmed or if it is in a closed status.
  
  
  Quantity Mismatch: The quantity being confirmed may exceed the quantity that is available for confirmation. This can happen if there are discrepancies in the planned versus actual quantities.
  
  
  Dependencies on Other Orders: There may be dependencies on other production orders or processes that need to be completed before the current order can be fully confirmed.
  
  
  System Configuration: There could be configuration issues in the JIT settings or in the production order management that prevent the confirmation from being processed.
  
  
  Solutions:
  
  
  Check Order Status: Verify the status of the production order. Ensure that it is in a state that allows for confirmation (e.g., not already confirmed or closed).
  
  
  Review Confirmation Data: Ensure that all necessary data for the confirmation is complete. Check for any missing components or operations that need to be confirmed first.
  
  
  Adjust Quantities: If the quantity being confirmed is incorrect, adjust it to match the available quantity for confirmation.
  
  
  Re-select the Order: As the error message suggests, try re-selecting the order or operation you are trying to confirm. Sometimes, simply re-attempting the confirmation can resolve transient issues.
  
  
  Consult Documentation: Review SAP documentation or help resources related to JIT and production order confirmations for any specific configuration or process requirements.
  
  
  Contact Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your specific system configuration and processes.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO11N (for confirmation of production orders) and COHV (for mass processing of production orders).
  SAP Notes: Check for any SAP Notes related to JIT and confirmation errors that may provide additional insights or patches.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to diagnose and resolve the JIT00456 error in your SAP system.
