SAP Travel Management- alternative expense receipt cost assignment button not shown

[giampierograceffa]

Hello Gurus,

in the Travel Management module, in the transactions PR05/TRIP I need to activate the expense receipt cost assignment.

The button 'alternative expense receipt cost assignment button' that allows users to assign an expense receipt to alternative cost assignment in fact it's not visible, how can I enable this button?

I have checked everywhere, also in the trip schema but I didn't found anything yet.

Thanks.

Regards.
