Identifying the last publisher name in IDT

Hello Experts,

I need your help on the below issue.

We want to known  is there any provision in BI 4.0 to come to known the details like "who had done the  last modification of the IDT"

We had checked in audit details ,the required details are not audited.

In the IDT as shown below,when we kept the mouse pointer to any IDT,it showing the last publisher  name  and published date.

But the problem here is published date is showing correct and LAST PUBLISHER name is showing wrong.

BI 4.0 version is SP4 patch5

We require your help on  this issue.

Regards,

Vinay
