SAP Error Message - Details

• Message type: E = Error

• Message class: S_BCFG_API - Exception texts for package S_BCFG_API_*

• Message number: 001

• Message text: The last container operation contradicts a preceding operation, key=&1.

What causes this issue?

The caller tried to add contradicting entries to a container, e.g.
add a line to a container which already contained a deletion for the
same table and key<(>,<)>
add a deletion to a container which already contained a line for the
same table and key.
Containers will not accept lines and deletions for the same key.

System Response

An unchecked exception is thrown.

How to fix this error?

When lines resp. deletions in a container are no longer needed, they can
be removed from it. Putting reverse entries into the container will not
work, because the BC API interprets them as contradictory and assumes a
programming error in this case.

• What is the cause and solution for SAP error message S_BCFG_API001 - The last container operation contradicts a preceding operation, key=&1. ?

  The SAP error message S_BCFG_API001 indicates that there is a contradiction between the last container operation and a preceding operation in the context of Business Configuration (BC) or similar configuration tasks. This error typically arises when there is an inconsistency in the configuration data being processed, often related to the sequence of operations or the state of the data.
  Cause:
  
  
  Inconsistent Operations: The error usually occurs when an operation that modifies a configuration object (like adding, changing, or deleting a configuration) contradicts a previous operation. For example, if you try to delete a configuration that has already been modified or if you attempt to add a configuration that conflicts with an existing one.
  
  
  Data Integrity Issues: There may be issues with the integrity of the data being processed, such as missing dependencies or incorrect relationships between configuration objects.
  
  
  Concurrency Issues: If multiple users or processes are trying to modify the same configuration object simultaneously, it can lead to conflicts.
  
  
  Incorrect Sequence of Operations: The operations may not be executed in the correct order, leading to a situation where the system cannot reconcile the changes.
  
  
  Solution:
  
  
  Review the Operations: Check the sequence of operations that were performed. Ensure that they are logically consistent and that no operation contradicts a previous one.
  
  
  Check for Dependencies: Verify if there are any dependencies or relationships between the configuration objects that need to be respected. Ensure that all required configurations are in place before performing operations.
  
  
  Rollback Changes: If possible, rollback the last operation that caused the error and reapply the changes in the correct order.
  
  
  Consult Logs: Look at the application logs or transaction logs to get more details about the operations that were performed. This can help identify the specific operation that caused the contradiction.
  
  
  Test in a Development Environment: If you are unsure about the changes, replicate the scenario in a development or test environment to identify the root cause without affecting production data.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. Provide them with the error message, context, and any relevant logs.
