• What is the cause and solution for SAP error message CRM_ES013 - Implicit keys are not possible when explicit keys are already defined ?

  The SAP error message CRM_ES013, which states "Implicit keys are not possible when explicit keys are already defined," typically occurs in the context of SAP CRM (Customer Relationship Management) when there is a conflict between implicit and explicit key definitions in a data model or configuration.
  Cause:
  This error arises when you attempt to define implicit keys in a context where explicit keys have already been defined. In SAP, keys are used to uniquely identify records in a database table or structure. 
  
  Explicit Keys: These are keys that are explicitly defined in the data model. They are usually specified in the table or structure definition.
  Implicit Keys: These are keys that are automatically generated by the system based on certain fields or criteria.
  
  When both types of keys are defined in the same context, the system cannot determine which key to use, leading to this error.
  Solution:
  To resolve the CRM_ES013 error, you can take the following steps:
  
  
  Review Key Definitions: Check the data model or structure where the error is occurring. Look for any explicit key definitions that may conflict with implicit keys.
  
  
  Remove Implicit Key Definitions: If explicit keys are already defined, you should remove any implicit key definitions that are not necessary. This can usually be done in the data model configuration.
  
  
  Modify Key Definitions: If you need both types of keys, consider modifying the structure to ensure that only one type of key is defined. You may need to consult with your SAP development team or refer to the documentation for the specific data model you are working with.
  
  
  Check Custom Code: If you have custom code or enhancements, review them to ensure that they are not inadvertently causing this conflict.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or updates regarding this error. There may be specific patches or recommendations provided by SAP.
  
  
  Testing: After making changes, test the configuration to ensure that the error no longer occurs and that the system behaves as expected.
