Hi Krishna Sagar,
As per my knowledge, when we make changes to smartforms, we need to take care about some points like....
- We need to call the Smartform FM once again in driven program, if we change the fields in Smartform(Form interface).
- Check the SSF_FUNCTION_MODULE_NAME importing SF name and exporting name.
Apart from these please check whether the moved request contains all the relevant objects are not like SF, SF style if any, Driver program.
I think with these your problem may clear,
Thanks and regards,
Prasanth.
