Hi Feiyun,
Table STXFADMI is only contains smartforms names, some more table are also exist, which contains smartforms information like
STXFCONT Smart Forms: Form Subobjects (Active)
STXFCONTR Smart Forms: Runtime Objects
STXFCONTS Smart Forms: Form Subobjects (Saved)
STXFCONTV Smart Forms: Form Subobjects - Versions
STXFOBJT Smart Forms: Subobject Long Texts
But you can get SMARTFORMS information in TADIR table also, with condition
OBJECT = 'SSFO '. (SAP Smart Form).
OBJ_NAME ="Smartforms Name".
You will get Package Name in DEVCLASS field.
Regards,
Praveer.
