Resolution

  • In brief: it takes more time to export to some format than others because each exporting format are really different, and supports different functionalities, therefore more functionalities it supports, more time it takes to export the report.  For a list of supported functionalities by exporting format, see the SAP Knowledge Base Article 1946358 
                  
  • In more details:
         
    • There are two types of exporting format in Crystal Reports:
      • Record based;
      • Page based  
             
    • Record based format
      • Export data with no formatting, or very limitted formatting, and therefore those simpler format export faster.
      • Record based formats are: Text, CSV, Microsoft Excel Workbook Data-only (xlsx), XML, ODBC, etc...
             
    • Page base format
      • Export the formatting of the report, as much as possible, and it is therefore much more complex to export a report to those formats, by consequent, it takes more time to export the report. For a list of supported functionalities by exporting format, see the SAP Knowledge Base Article 1946358 
      • Page base formats are: Microsoft Excel (97-2003) (xls), Microsoft Word (97-2003), Rich Text Format (RTF), PDF, etc...
              
    • Also, generating the format of destination could be much more complex for some format than other. 
      For example: Generating a simple text file is simpler than generating a PDF document.
