change special ledger structure

[jolinchew]

we have one special ledger Z1, live on 2011, now we want to add several fields (from BSEG, like business area, tax)to Z1. should we use GCIN to change object table, if we change object table, does summary table and line item table aslo automatically be updated. what other steps we should do, the field movement is RFBU, flow from FI

I think there is always an option to re-load whole set of data into SPL, isn't it?

[jolinchew]

but what are the steps to change structure then reload?
