Edit PSA data, infobject cannot see

Hello BW Experts,

My PSA only shows 99 infobjects. I need to edit the infobject 110.

To view the IOB1 and its value:

I go to PSA > change variants > select the infobect IOB1 and now I could see the infobject and its values that I want to edit.

To edit:

But when I double click or press the change mode button I get the fields to be edited but not this IOB1. How can I edit the value of the IOB1 which is 110 in position and my PSA only shows first 99 in sequence for edit.

Wondering if there is any alternate way to edit this data.

Suggestions appreciated.

Thanks,
