• What is the cause and solution for SAP error message CRM_BSP_CUSTCHECK018 - Group &1/item &2: field (type &3) cannot have any links ?

  The SAP error message CRM_BSP_CUSTCHECK018 typically occurs in the context of SAP CRM (Customer Relationship Management) when there is an issue with the configuration of a field in a Business Server Page (BSP) application. This error indicates that a specific field (identified by the group and item number) is of a type that does not support links, but a link has been attempted to be created or is present.
  Cause:
  
  Field Type Restriction: The field type specified (type &3) does not allow for links. This could be due to the nature of the data that the field is intended to hold.
  Configuration Error: There may be a misconfiguration in the BSP application or the underlying data model that is causing the system to incorrectly interpret the field as capable of having links.
  Data Model Issues: The data model may not be set up correctly, leading to inconsistencies in how fields are treated.
  
  Solution:
  
  Check Field Configuration: Review the configuration of the field in the BSP application. Ensure that the field type is appropriate for the intended use. If the field is not supposed to have links, ensure that no link-related properties are set.
  Modify Field Type: If the field is incorrectly set to a type that does not support links, consider changing the field type to one that does support links, if that aligns with your business requirements.
  Review BSP Application Logic: Check the logic in the BSP application to ensure that it is not attempting to create links for fields that are not designed to support them.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the field types and their capabilities.
  Testing: After making changes, test the application to ensure that the error no longer occurs and that the functionality works as expected.
