• What is the cause and solution for SAP error message WS_TOOL182 - Restriction: Parameter &1 may not begin with a number ?

  SAP Error Message:
  
  WS_TOOL182 Restriction: Parameter &1 may not begin with a number
  
  Cause:
  This error occurs when a parameter name in a Web Service or related SAP tool (such as SOAMANAGER, Web Service configuration, or ABAP proxy generation) starts with a numeric character. According to SAP naming conventions and XML standards, parameter names (or variable names, identifiers) cannot begin with a digit. They must start with a letter or underscore.
  For example, a parameter named 1CustomerID will trigger this error because it starts with 1.
  
  Explanation:
  
  In XML and many programming languages, identifiers (like parameter names) must start with a letter or underscore.
  SAP enforces this rule to ensure compatibility and correctness in generated WSDLs, proxies, and service interfaces.
  This restriction helps avoid issues in service consumption and integration.
  
  
  Solution:
  
  Rename the parameter so that it starts with a letter (A-Z, a-z) or underscore (_).
  For example, change 1CustomerID to CustomerID or _1CustomerID.
  Update the relevant data structures, proxy classes, or service definitions accordingly.
  Regenerate the proxy or service after renaming the parameter.
  
  
  Related Information:
  
  This error is commonly encountered during:
  
  Proxy generation in transaction SPROXY.
  Web service configuration in SOAMANAGER.
  WSDL import or generation.
  
  
  SAP naming conventions for parameters and variables:
  
  Must start with a letter or underscore.
  Can contain letters, digits, and underscores.
  
  
  Check the data element or structure definition in ABAP Dictionary if the parameter is derived from there.
  If the parameter name comes from an external system or WSDL, coordinate with the provider to correct the naming.
