Reference table of structure LBBIL_INVOICE ?

Question

Hi Expert,
I want to create smartform based on standard SAP program.
Printing Program : RLB_INVOICE
Smartforms : SF_LB_INVOICE
I have problem during change smartform. The interface of smartform is IS_BIL_INVOICE TYPE LBBIL_INVOICE. This structure contain of other table type or other structure. I think this structure have complete data. But functional design always create design using database table that I must fetch the data.
Is there any body can tell me what is reference table of each element of structure LBBIL_INVOICE ?
Thanks beforehand.

Hi ,
These structures are deep structures and you  will have  the table  entered  as a field of this structure .
All the values are populated in these structures . Else copy the standard driver program  and  the key field is always populated in nast table get the keyfield from nast table ( nast  structure gets populated  autmatically  check in the std driver program )
eg   (   move nast-objky(10) to g_ebeln   )
based on this key field fetch all the other values you require in the driver program and pass it to your smart form .But i must say this is  not a smart  thing to do if you already have all the data available in the  standard structure .
give your  driver program and smartform name in NACE txn. also define the output type.  all the other data  retrival  can also be done in the code editor of smart form  in case you need some other values at a later stage.here is the sample code
FORM GET_DATA .
check not nast-objky is initial.
  move nast-objky(10) to g_ebeln.
