/n/sapapo/sdp94(How to change the mode from display to change mode)

Hello team,

In /n/sapapo/sdp94 we have 4 planning books.

Out of 4 i can go to edit mode in all planning book except one planning book.

I dont see the edit button on the top left corner.

So could any one help me to resolve this issue.
