  Cause:
  The error message UD349 is triggered when the cardinality defined for a relationship is not valid. Cardinality refers to the numerical relationships between entities, such as one-to-one, one-to-many, or many-to-many. Common causes for this error include:
  
  Incorrect Cardinality Definition: The cardinality specified does not conform to the expected values or rules defined in the system.
  Data Model Constraints: The data model may have constraints that are not being met by the cardinality you are trying to set.
  Missing or Incorrect Configuration: There may be missing configurations or incorrect settings in the data model that lead to this error.
  
  Solution:
  To resolve the UD349 error, you can take the following steps:

  1:1 (one-to-one)
  1:N (one-to-many)
  N:M (many-to-many)
  
  Make sure you are using the correct format and values as per the system's requirements.
  
  
  Review Data Model: Examine the data model to ensure that the relationships between entities are correctly defined and that the cardinality aligns with the logical structure of the data.
  
  
  Consult Documentation: Refer to SAP documentation or help resources specific to the module you are working with. This can provide insights into valid cardinality settings and any constraints that may apply.
