replacement fm needed

Hi,

we are working on unicode upgrade project and there is a error saying that main program for function module missing.

the funciton module does not exist in the new version but present in old version.

below is the error....

Main Program for Function Module LCT_ORDER_DISPLAY_DEPENDENCIES Missing

(LCT_ORDER_DISPLAY_DEPENDENCIES is not shown in the database table TFDIR)

Caution: SLIN observes the catching of the runtime error by

CX_SY_DYN_CALL_ILLEGAL_FUNC

can anyone suggest a replacement for function module"<b>LCT_ORDER_DISPLAY_DEPENDENCIES</b> ".
