Message No. R7042 - Extension can be problematic

Hi experts,

I have a small problem when I want to change the length of a Z - InfoObject Characteristic from 0004 to 0008. Even though my InfoObject is nowhere related to any hierarchies or cubes, when I activate the infoobject, it doesn't allow me to do so and gives me this error:

(Message No. R7042).

Diagnosis

The length of characteristic Z-InfoObject has been extended from 000004 to 000008.

Could you please let me know how can I fix this issue?

Thank you,

Regys
