Hi Ana,
Material ledger has 2 big features: Parallel currencies/valuations and Actual Cost settlement. If your requirement is to have material ledger only for actual costs purposes it's possible to have only one currency type setup in ML Currency Profile.
In my opinion there are some advantages of having only the currency type 10 (local currency):
- Performance, because transactional tables such as CKMLCR, CKMLPRKEPH, MLCD, etc... will have up to 3 times less records as CURTP is table key. In consequence, ML Cockpit run will be faster.
- Less chances of erros. If you have several currencies, sometimes erros occurs in only one cur type (for exemple Negative Price).
- Have to maintain several currencies in manual postings like MR22/MR21/CKMLCCC.
The disaventage is that if you don't have a hard currency in ML you will not be able to valuate your stocks for index purposes if your local currency suffer with inflation.
Regards,
