Hello Manoj,
Info structure from S000 to S499 standard info structure and you can't change this info structure,
No option for S076 to changes
Through MC21/22/23 you can create/change/display the info structure (Avlb range S500 to S999)
For this info structure you can add and remove the Characteristic as per your requirement
I hope this information helpful to you
