Hi,
The reason there are records in that table is because the interop is turn on.
Check the P0400047 (interactive Version) the last tab. If the is a value there, check that version in the P0400048. If there is no value, check ZJDE0001. If you do not want records written in that table, clear both processing option in the P0400048.
This is used for interfaces to other system. If you company is not interfacing to other system, you can clean that table.
There is the same processing options for G/L and A/R and A/B.
Hope that Helps
