• What is the cause and solution for SAP error message SALV_EXCEPTION103 - The passed column must be of type &4 ?

  The SAP error message SALV_EXCEPTION103 typically occurs when working with the SAP ALV (ABAP List Viewer) framework, particularly when you are trying to manipulate or display a column in an ALV grid or list. The error message indicates that the column you are trying to pass to the ALV is not of the expected data type.
  Cause:
  The error message SALV_EXCEPTION103 The passed column must be of type &4 suggests that the column you are trying to use in the ALV is not of the correct type. This can happen due to several reasons:
  
  Data Type Mismatch: The data type of the column in your internal table does not match the expected type in the ALV.
  Incorrect Field Mapping: When defining the field catalog or the structure of the internal table, the field types may not align with what the ALV expects.
  Improper Configuration: The configuration of the ALV grid or list may not be set up correctly, leading to type mismatches.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Data Types: Ensure that the data types of the columns in your internal table match the expected types in the ALV. You can do this by checking the structure of the internal table and the field catalog.
  
  
  Field Catalog Configuration: If you are using a field catalog, make sure that the field types specified in the catalog match the types of the fields in your internal table. For example, if you have a numeric field in your internal table, ensure that it is defined as a numeric type in the field catalog.
  
  
  Debugging: Use the debugger to inspect the values and types of the columns being passed to the ALV. This can help you identify where the mismatch is occurring.
  
  
  Data Conversion: If necessary, convert the data types of the columns in your internal table to match the expected types. You can use ABAP data conversion functions to achieve this.
  
  
  Review Documentation: Refer to the SAP documentation for the ALV framework to understand the expected data types and configurations.
  
  
  Related Information:
  
  ALV Documentation: Review the official SAP documentation for the ALV framework to understand the requirements for data types and field catalogs.
  SAP Community: Check the SAP Community forums for similar issues and solutions shared by other developers.
  ABAP Development: Familiarize yourself with ABAP data types and structures, as understanding these will help you avoid similar issues in the future.
