I'm developing a report where basically have to show the SES associated to a Line Item of FI Document.
I have consulted and revised the tables BKPF, BSEG, EKBE, EKPO, MSEG, ESSR and I didn find any 1:1 relationship between a FI Line Item and a SES number.
Is this possible? Can I find a 1:1 relationship? If so, how?
