• What is the cause and solution for SAP error message SDDL_PARSER_MSG458 - Text association "&1" must be a "to many" association ?

  The SAP error message SDDL_PARSER_MSG458 indicates that there is an issue with the definition of an association in your data model, specifically that the text association you are trying to define must be a "to many" association. This error typically arises in the context of SAP's data modeling tools, such as when working with Core Data Services (CDS) views or other data definitions.
  Cause:
  The error occurs when you attempt to create a text association (which is used to provide a textual representation of an entity) that is not defined as a "to many" association. In SAP data modeling, a text association is expected to link to multiple records (i.e., it should be a "to many" relationship) because it is meant to provide a description or label for a collection of items.
  Solution:
  To resolve this error, you need to ensure that the association you are defining is indeed a "to many" association. Here are the steps you can take:
  
  
  Check the Association Definition: Review the definition of the association in your data model. Ensure that it is defined as a "to many" association. This typically involves checking the cardinality of the association.
  
  
  Modify the Association: If the association is currently defined as "to one" or has incorrect cardinality, modify it to be "to many". This can usually be done in the data modeling tool you are using (e.g., ABAP Development Tools, Eclipse).
  
  
  Review Related Entities: Ensure that the entity you are associating with has the correct relationship defined. The target entity should be capable of having multiple instances related to the source entity.
  
  
  Test the Changes: After making the necessary changes, activate the data model and test it to ensure that the error is resolved.
  
  
  Related Information:
  
  Documentation: Refer to the SAP documentation on data modeling and associations for more detailed information on how to define associations correctly.
