Is there audit on the repair estimate / Actuals tab of the Repair Order in depot repair?

In Oracle Ebs ,  qry for a repair order in the depot repair module. go to the estimates tab, change the original value of estimates to new value.

is there a provision of audit history in the estimates tab?

if yes, kindly share the details around the same.

{

take for example, i have created RO with 1 charges line in Repair Estimate. $50,000

the next week, price change, the same line amount is change to $65,000

we need to track the changes

because if this happen between different period

we need to know that there's changes happen to this line

so that report can appear having additional $15,000 booking in the next period report
