po text

hi all,

can anyone say where all the material po text are stored in which tables.

I need the table name .

I did find one thing going to purchase order and double clicking the text feild and going to GOTO from menu

and also went to se11 and entered STXL and found CLUSTD is the feild and feild type STXLDUMMY2 is that the one where long text material po is stored. Can i use this in Functional spec?

and i also found one through info record RM06I as structure name LTEX1as feild name.

Is there anything apart from this or which one should i use in functional spec.
