Traceability between the expense sheet line and project transaction

Hello,

When a expense sheet is authorized, for each line in the expense sheet, a project transaction line is created.

The expense reference is copied to Internal Comment field in every project transaction generated, but I can’t find the traceability between the expense sheet lines and their corresponding project transactions lines.

I would like to identify which project transaction line corresponds to each expense sheet line. Is it posible?.

(We are working with IFS 9).

Thanks in advance,

Amaia
