Checking whether function module is documented or released

Hi Experts,

I have a query on checking whether function module is documented and released.We can check this in Attributes of function module, but is there any way where we can check this through code. Is there any standard FM or table where we can give function module name and it will return result that whether particular FM is documented or released.

Please let us know any table or FM readily available for this.

Regards,

Sanjana
