• What is the cause and solution for SAP error message REST_CORE_TEXTS016 - Only one colon ':' permitted in URI template & ?

  The SAP error message REST_CORE_TEXTS016 indicates that there is an issue with the URI template used in your RESTful service. Specifically, the error states that only one colon (:) is permitted in the URI template. This typically occurs when defining a URI template for a service in SAP Gateway or OData services.
  Cause:
  The error is caused by the incorrect formatting of the URI template. In a URI template, colons are used to denote parameters. If there are multiple colons in the URI template, it violates the expected format, leading to this error.
  Solution:
  To resolve this error, you should check the URI template you have defined for your service. Here are the steps to fix the issue:
  
  
  Review the URI Template: Look at the URI template you have defined in your service. Ensure that it contains only one colon (:) for parameterization.
  
  
  Correct the Format: If you find multiple colons, you need to adjust the template. For example, if your URI template looks like this:
  /entity/:param1/:param2
  You should change it to have only one parameter:
  /entity/:param1
  or combine parameters in a different way that adheres to the single colon rule.
  
  
  Test the Changes: After making the necessary adjustments, test the service again to ensure that the error is resolved.
  
  
  Related Information:
  
  
  URI Template Syntax: Familiarize yourself with the correct syntax for URI templates in OData services. The general format is:
  /entitySetName/:parameterName
  where parameterName is the variable part of the URI.
  
  
  SAP Documentation: Refer to the official SAP documentation for more details on URI templates and RESTful services. This can provide additional context and examples.
  
  
  Debugging Tools: Use debugging tools available in SAP Gateway or your development environment to trace the request and identify where the URI template is being defined.
  
  
  By following these steps, you should be able to resolve the error and successfully define your URI template in SAP.
