SAP Error Message - Details

• Message type: E = Error

• Message class: COM_PME_PARSER - Configuration

• Message number: 131

• Message text: Constraint has too many value assignment alternatives: &1

What causes this issue?

There is a maximum number of value assignment alternatives (rules) for
an individual constraint. The number of value assignment alternatives
is determined by the value inferences required and the use of the
logical operators OR and NOT.

System Response

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 COM_PME_PARSER131 - Constraint has too many value assignment alternatives: &1 ?

  The SAP error message COM_PME_PARSER131 indicates that a constraint in the Product Master or similar configuration has too many value assignment alternatives. This typically occurs in the context of Product Lifecycle Management (PLM) or Variant Configuration (VC) where constraints are defined for product characteristics.
  Cause:
  The error arises when the number of alternatives specified for a constraint exceeds the allowable limit set by the system. This can happen due to:
  
  Excessive Alternatives: The constraint is defined with too many possible values or combinations, which can lead to performance issues or exceed system limits.
  Complex Configuration: The configuration of the product may be overly complex, leading to a high number of alternatives being generated.
  Incorrect Configuration: There may be a misconfiguration in the way the constraints are set up, leading to unintended high counts of alternatives.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Constraints: Check the constraints defined for the product. Simplify them if possible by reducing the number of alternatives or combining similar alternatives.
  
  
  Limit Alternatives: If the constraint is necessary, try to limit the number of alternatives by grouping similar characteristics or using ranges instead of individual values.
  
  
  Optimize Configuration: Look for ways to optimize the configuration of the product. This may involve restructuring how characteristics and constraints are defined.
  
  
  Check System Limits: Consult SAP documentation or your system administrator to understand the limits imposed by your specific SAP version and configuration. 
  
  
  Testing: After making changes, test the configuration to ensure that it meets business requirements without exceeding system limits.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address this issue or provide guidance on best practices for defining constraints.
  
  
  Related Information:
  
  SAP Documentation: Review the SAP Help Portal for documentation on Product Master Data and Variant Configuration.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have implemented.
  Performance Considerations: Be aware that overly complex configurations can lead to performance degradation, so always aim for a balance between flexibility and simplicity.
