Hi Prasanna, Prashanth (RIS-CON) •,
Welcome to Microsoft Q&A forum and thanks for using Azure Services.
As I understand, you want to know the limit of Database size in Export of Bacpac.
If you are exporting to blob storage, the maximum size of a BACPAC file is 200 GB. To archive a larger BACPAC file, export to local storage with SqlPackage.

Hope the information helps. Please let us know if you face any issue in performing this export.
