Hi Durga,
I understand that it's an old thread, but did you manage to figure out the cause for the same.
I have come across a similar situation.
User (spanish) is trying to create personal views on infospace but not able to save it.
He is able to give name to personal view but there ok button is not available.
However I tried with users alias, I was successfully able to create personal views.
Even tried changing language, regional format settings to spanish but could not recreate it from my end.
Currently I am using SAP BI app 6.1.11 on SAP BI 4.1 SP3 patch 1 servers. I am yet to check user's
app version on Ipad.
Meanwhile could you suggest me if you have observed any other settings which may cause such issue?
