How to set 'Material Master' tab as default in standard transaction CG54?

Hi All

I am having a requirement to call the transaction CG54 from a custom program. On calling the transaction, I need to put some default values to the input fields and the default tab selected should be 'Material Master'. I am able to default input fields using BDC Transaction call. Can anybody guide me how to set Material Master tab as the default tab selected?

Thanks in advance
