• What is the cause and solution for SAP error message SDEST020 - RFC destinations of type & are not supported by API ?

  The SAP error message SDEST020 indicates that there is an issue with the RFC (Remote Function Call) destination configuration in your SAP system. Specifically, it states that RFC destinations of a certain type are not supported by the API you are trying to use.
  Cause:
  The error typically arises due to one of the following reasons:
  
  
  Unsupported RFC Destination Type: The RFC destination you are trying to use is of a type that is not supported by the API. For example, if you are trying to use a destination that is configured for a specific type of communication (like a type that is not meant for the API you are using), this error will occur.
  
  
  Configuration Issues: There may be misconfigurations in the RFC destination settings, such as incorrect parameters or missing entries.
  
  
  API Limitations: The API you are using may have limitations regarding the types of RFC destinations it can work with.
  
  
  Solution:
  To resolve the SDEST020 error, you can take the following steps:
  
  
  Check RFC Destination Type:
  
  Go to transaction SM59 in your SAP system.
  Review the RFC destination that is causing the issue.
  Ensure that the destination type is compatible with the API you are using. Common types include:
  
  T: TCP/IP connections
  3: ABAP connections
  H: HTTP connections
  
  
  If the type is not supported, you may need to create a new RFC destination of a supported type.
  
  
  
  Review Configuration:
  
  Ensure that all required parameters for the RFC destination are correctly configured.
  Test the RFC connection using the "Connection Test" feature in SM59 to ensure it is working properly.
  
  
  
  Consult Documentation:
