Dimension Lock Problem

Hello experts,

I've a dimension lock issue.

One of my Dimensions in the Appset is locked by a user. Hence i'm unable to maintain Dimension members as it is in locked state.

However the user have logged into the Appset and tried to maintain the dimension. But strangely it gave "Dimension locked by user" pop-up again , though it is his own id.....

Did any one face this issue?

We have tried processing the dimension and it is successful but still getting the error.

Pls suggest
