• What is the cause and solution for SAP error message AD545 - Define a data class and size category for transparent table & ?

  The SAP error message AD545 indicates that a transparent table has not been properly defined with a data class and size category. This is a common issue when creating or modifying database tables in the ABAP Dictionary (SE11).
  Cause:
  The error occurs because every transparent table in SAP must be assigned a data class and a size category. The data class determines where the table data is stored (e.g., in the database, in memory, etc.), while the size category defines the expected size of the table and helps the database optimize storage.
  Solution:
  To resolve the error AD545, follow these steps:
  
  
  Open the ABAP Dictionary:
  
  Go to transaction code SE11.
  
  
  
  Locate the Table:
  
  Enter the name of the transparent table that is causing the error and click on the "Display" button.
  
  
  
  Edit the Table:
  
  Click on the "Change" button to edit the table definition.
  
  
  
  Define Data Class:

  APPL1: Transaction data
  APPL2: Customizing data
  
  
  
  
  
  Define Size Category:

  2: Large table (up to 10,000 entries)
  3: Very large table (more than 10,000 entries)
