• What is the cause and solution for SAP error message WER_UI032 - Structure/table type field not allowed. ?

  SAP Error Message:
  
  WER_UI032 - Structure/table type field not allowed
  
  Cause:
  This error occurs when a structure or table type field is used in a context where only elementary (single) data fields are allowed. For example, in certain UI configurations, data binding, or field declarations, SAP expects a simple data element but finds a complex type (structure or table type) instead.
  Common scenarios include:
  
  Defining a UI element or screen field with a data type that is a structure or internal table instead of a single field.
  Using a structure or table type in a place where only elementary fields are permitted, such as in a parameter, attribute, or field catalog.
  
  
  Solution:
  
  Check the field definition: Verify the data type of the field causing the error. It should be an elementary data type (e.g., CHAR, NUMC, INT, etc.) rather than a structure or table type.
  Adjust the data binding: If you are binding UI elements or parameters, ensure you bind to a single field within the structure, not the entire structure.
  Modify the data declaration: If you have declared a field as a structure or table type, change it to an elementary type or use a component of the structure.
  Review the context: For example, in ALV field catalogs, only elementary fields are allowed as column fields, not structures or internal tables.
  Debug or check the code/UI configuration: Identify where the structure/table type is incorrectly used and replace it with an appropriate elementary field.
  
  
  Related Information:
  
  This error is common in ABAP programming when dealing with screen fields, data binding in Web Dynpro, or ALV grid configurations.
  SAP Note or documentation related to the specific module or UI technology you are using may provide additional guidance.
  When working with complex data types, always ensure that UI elements or parameters refer to elementary fields or components of structures.
  In Web Dynpro ABAP, for example, context attributes must be elementary types for certain UI elements.
  
  
  Summary:
  
  WER_UI032 indicates that a structure or table type field is used where only an elementary field is allowed. The fix is to replace the structure/table type with an elementary field or a component of the structure in the relevant declaration or binding.
