Build Source Data Vault out of SAP ACDOCA Table


I have received two CSV files of the SAP BKPF and ACDOCA tables. By looking into these files, it looks like these two tables are connected through certain keys where BKPF is the parent and ACDOCA is the child. But moving ahead with building the source data vault on Vaultspeed, it was suggested to me that the ACDOCA table should be split into different subject areas like asset accounting and etc. But it looks like we are moving towards normalizing this table, as it was denormalized by SAP itself in the ACDOCA table. Is this a good approach to take?
