BOM explosion

Hello,
I want to use tibom.dll027 for bom explosion.
At the moment it does not a real explosion, but only returns items of the 1st level.

What am I doing wrong?

Regards
Martin

This is my code:

Code:

function long bom.check.for.item(domain tcitem item.e, domain tcitem item.c)

{

        long it

        it = tibom.dll0270.open.bill.of.material.iterator(get.logistic.compnr(), item.e )

        domain tcitem item.tra

        while(tibom.dll0270.get.next.bill.of.material.line(it))

                

                item.tra = tibom.dll0270.get.item(it)

               

               

                if item.tra = item.c then

                        tibom.dll0270.close.bill.of.material.iterator(it)

                        return (1)

                        

                endif

        endwhile



        tibom.dll0270.close.bill.of.material.iterator(it)

        return (0)

}
