  The SAP error message 0K544 indicates that the field catalog for a report or output contains more than 99 columns, which exceeds the limit set by the SAP system. This error typically occurs when you are trying to generate a report or output that includes too many fields in the field catalog.
  Cause:
  The primary cause of this error is that the field catalog, which defines the structure of the output (including the columns to be displayed), has more than 99 entries. This limit is imposed by the SAP system to ensure performance and manageability of the output.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Reduce the Number of Columns:
  
  Review the fields you are including in the output and remove any unnecessary columns. Focus on the most relevant data that needs to be displayed.
  
  
  
  Split the Output:
  
  If you need to display a large number of fields, consider splitting the output into multiple reports or sections. For example, you could create separate reports for different categories of data.
  
  
  
  Use Subreports:
  
  If applicable, use subreports to display additional details. This way, you can keep the main report within the 99-column limit while still providing access to more data.
  
  
  
  Dynamic Field Selection:
  
  Implement logic to dynamically select fields based on user input or specific criteria. This can help in limiting the number of columns based on the context of the report.
  
  
  
  Check Custom Code:
  
  If you are using custom ABAP code to generate the report, review the code to ensure that it is not inadvertently adding too many fields to the field catalog.
  
  
  
  Related Information:
