how to get a legal message printed on an AR transaction from a tax rate code ?

Summary:

I have created a "LEGAL Justification Message Reporting code " for a given TAX RATE CODE. when looking at a transaction using this tax rate code , there is no legal message ID in any ZX_lines column.

Content (required):

In " Manage tax reporting types" task

I have created a tax reporting type , "with reporting type use " = "Process result" & " tax rate" and reporting type purpose legal justification message type.

In " manage tax rate and recovery rates" task

i have edited an existing tax rate code and linked the created reporting message using the "legal justification message reporting code " menu

using this process, i can't see in any tables the legal message ID for a new created AR invoice with this rate code .
