How To Fix ATP_ABC_LOGIC000 - ABC cannot be executed: the substitution stategy contradicts the process.

SAP Error Message - Details

• Message type: E = Error

• Message class: ATP_ABC_LOGIC -

• Message number: 000

• Message text: ABC cannot be executed: the substitution stategy contradicts the process.

What causes this issue?

The substitution item type in substitution strategy &V3& violates the
conditions of the current process for item &V2& in document &V1&.

System Response

Alternative-Based Confirmation (ABC) is not executed. Instead, an
availability check is executed without ABC.

How to fix this error?

Change the substitution item type in the substitution strategy if the
availability check for the current process must include ABC.

• What is the cause and solution for SAP error message ATP_ABC_LOGIC000 - ABC cannot be executed: the substitution stategy contradicts the process. ?

  The SAP error message ATP_ABC_LOGIC000 indicates that there is a problem with the substitution strategy in the Advanced Planning (ATP) process. This error typically arises when the system encounters a contradiction in the rules or logic defined for substituting products during the ATP check.
  Cause:
  
  
  Contradictory Substitution Rules: The substitution strategy defined in the system may have conflicting rules that cannot be executed simultaneously. For example, if one rule states that a certain product can be substituted for another under specific conditions, and another rule states that it cannot be substituted under the same conditions, this will lead to a contradiction.
  
  
  Configuration Issues: There may be issues in the configuration of the ATP settings, such as incorrect settings in the material master or in the ATP configuration itself.
  
  
  Master Data Issues: The master data for the materials involved may not be set up correctly, leading to inconsistencies in how substitutions are handled.
  
  
  Solution:
  
  
  Review Substitution Strategy: Check the substitution strategy defined in the system. Ensure that there are no conflicting rules. You may need to adjust the conditions under which substitutions are allowed.
  
  
  Check Configuration Settings: Review the configuration settings for ATP in the SAP system. Ensure that all settings are correctly defined and that there are no inconsistencies.
  
  
  Validate Master Data: Ensure that the master data for the materials involved in the ATP check is correctly set up. This includes checking the material master records, especially the substitution settings.
  
  
  Testing: After making changes, perform tests to ensure that the ATP process works as expected without triggering the error message.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring substitution strategies and resolving ATP-related issues.
  
  
  Seek Expert Help: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide deeper insights into the ATP configuration and troubleshooting.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for configuring ATP and substitution strategies.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD04 (Stock/Requirements List) and MD01 (MRP Run) to analyze the ATP situation.
  Documentation: Review SAP Help Portal for detailed documentation on Advanced Planning and ATP processes.
  
  By following these steps, you should be able to identify the root cause of the ATP_ABC_LOGIC000 error and implement a solution to resolve it.
