• What is the cause and solution for SAP error message SALV_X_API053 - Table must have the same type as previously passed to this instance ?

  The SAP error message SALV_X_API053 indicates that there is a type mismatch in the data being passed to an instance of the SALV (SAP ALV) class. Specifically, it means that the table you are trying to use with the SALV API does not match the type of the table that was previously passed to that instance.
  Cause:
  This error typically occurs when:
  
  You are trying to add a new data table to an ALV object that has already been initialized with a different type of data table.
  The structure of the new table does not match the structure of the table that was initially passed to the ALV instance.
  There may be a programming error where the same ALV object is being reused incorrectly with different data types.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Types: Ensure that the data table you are trying to pass to the ALV instance has the same structure and type as the one that was previously passed. You can do this by checking the data definitions (like the structure or type) of both tables.
  
  
  Create a New ALV Instance: If you need to display a different type of data, consider creating a new instance of the ALV object instead of reusing the existing one. This way, you can pass the new table without causing a type mismatch.
  
  
  Review Code Logic: Go through your code to ensure that you are not unintentionally reusing the same ALV instance for different types of data. If you need to display multiple types of data, manage separate instances for each type.
  
  
  Debugging: Use debugging tools to trace the flow of your program and identify where the type mismatch is occurring. This can help you pinpoint the exact location in your code that is causing the issue.
