Question

what is line item display? Explain in detail.

Answer 1

hi rama,
            there are two type of data in database table.
header data: means data will be unique, there will be single row for key fields.
like bkpf , vbak, kna1 etc these have the unique data.
and second one is line item data.
LINE ITEM DATA: That have the multiple entries regarding key fields.
like bseg, vbap etc .
when you go for coding first you take the header data from header table because that are unique then on the reference of that unique data we pick up line item data from item table by joining those two table.
for ex bkpf have unique documnet no belnr so on the basis of belnr we picked the line item data from bseg.
jus take the refrence of below code that have the header and line item data from bkpf and bseg respectively.
