Hi Don,

You are thinking of AR :-) In AP it is APMAST/APYMST and APDIST/APYDST

>APMAST - Current A/P invoice header information
> APTRAN - Detail posting information per account per invoice in APMAST
>
>APYMST - History (period closing) information invoice headers
> APYTRN - Detail posting information

>These tables have parallel structures... Once you look at the tables, you should see the direct relations for invoice, vendors. Also, there are two field in the APTRAN and APYTRN tables: GLFPER and GLFYEAR for the fiscal period and fiscal year. These can be tied back to the GL table for actual dates that the given fiscal period/year relate to. Don't remember this one off hand.
