Here is the example ABAP code to call SAP SmarForms from a program or an ABAP report.
Please note that we have ABAP codes which call ABAP function SSF_FUNCTION_MODULE_NAME with formname parameter is set to the target SAP Smartforms document.
The SSF_FUNCTION_MODULE_NAME ABAP call returns the FM_NAME which is the compiled ABAP program identifier and is in type rs38l_fnam.
The returned fm_name variable is then called using an ABAP Call Function method to open Smartform.
While calling Smartform, the Table parameter is passed as an input argument.
