How to create a dynamic table relation

yekede

hi all,
i want to create a lookup for table A in table B using code in the lookup trigger of a field in table B.
ex: Form.runmodal(FormNo,RecordTableA) where FormNo is the lookupformid of table A. At design time i do not know which table is A, so i do not know the lookupformid of A. I can only get the tableA ID at run time. It is possible to create this type of tablerelation?
How can i achieve this?
Thanks

if you do

FORM.RUNMODAL(0,mytable);

nav will run the lookupformid of mytable.
but anyway...even if you use the above instruction, you'll need multiple variables for every possible table to be run, thus you'll need a case statement like this:

CASE TableID OF
  1: FORM.RUNMODAL(0,mytable1);
  2: FORM.RUNMODAL(0,mytable2);
END;

morale: a "joker" table variable does not exist in NAV
I hope I understood what you need...
