BTEs can be used both by SAP, third part vensdors and
customers. Each use their own function modules where the logic is
placed, so they don't interfere witj each other

OPEN_FI_PERFORM_<BTE-number> or
OUTBOUND_CALL_<BTE-number>. This function chekcs if
there are any active BTEs according to customizing.
