Once you have activated the smartform, go to the environment -> function module name. There you can get the name of FUNTION module name.

The key THING is the program that calls it. for instance, the invoice SMARTFORM LB_BIL_INVOICE is ran by the program RLB_INVOICE.

This program uses another FM to determine the name of the FM to use itself. The key thing is that when it calls this FM (using a variable to store the actual name), that the parameters match the paramters in your smartform.

Another thing to NOTE is that the FM name will CHANGE WHEREVER the SF is transported to.

So you need to use the FM to determine the name of the SF.

Here is the code that can be use to determine the internal name of the function module:

Code:

if sf_label(1) <> '/'. " need to resolve by name
move sf_label to externalname.
call function 'SSF_FUNCTION_MODULE_NAME'
exporting
formname = externalname
importing
fm_name = internalname
exceptions
no_form = 1
no_function_module = 2
others = 3.
if sy-subrc <> 0.
message 'e427'.
endif.
move internalname to sf_label.
endif.

It checks to see if the sf_label starts with a '/', which is how the internal names start. if it does, the name has already been converted. If not, it calls the FM and converts the name.

You would then CALL FUNCTION sf_label.

Once you have activated the smartform, go to the environment -> function module name. There you can get the name of funtion module name.

The key thing is the program that calls it. for instance, the invoice SMARTFORM LB_BIL_INVOICE is ran by the program RLB_INVOICE.

This program uses another FM to determine the name of the FM to use itself. The key thing is that when it calls this FM (using a variable to store the actual name), that the parameters match the paramters in your smartform.

Another thing to note is that the FM name will change wherever the SF is transported to.

So you need to use the FM to determine the name of the SF.

Here is the code that can be use to determine the internal name of the function module:

Code:

if sf_label(1) <> '/'. " need to resolve by name
move sf_label to externalname.
call function 'SSF_FUNCTION_MODULE_NAME'
exporting
formname = externalname
importing
fm_name = internalname
exceptions
no_form = 1
no_function_module = 2
others = 3.
if sy-subrc <> 0.
message 'e427'.
endif.
move internalname to sf_label.
endif.

It checks to see if the sf_label starts with a '/', which is how the internal names start. if it does, the name has already been converted. If not, it calls the FM and converts the name.

You would then CALL FUNCTION sf_label.
