Detailed scheduling view in planned order

Hi Experts,

In repetitive manufacturing process our client has created few planned orders manually as shown in the below screen shot

But someone of other user has performed performed the detailed scheduling by clicking push button. After that the planned order has changed as shown in the below screen shot

Now our client asked to remove the detailed scheduling tab from the planned order .

Is there any possibilities to remove that tab

thanks in advance

Regards
