AR Apply trsnaction is not showing in Document Inquiry form

Hi,

I have a weird issue with one of the AR transactions where it does not show the applied amount when i click on the amount remaining:

when i try to view the transaction  through Inquiry - >Transaction by customer and then click on the amount remaining, it shows the applied payment amount propery as expected

but when i try Inquiry - > Transaction by document  and then clcik again on amount remaining, it show nothing

Any idea which table this window read from?

Many thanks
