There are two screens which have to be maintained for each new GL account. The first is at ‘chart of account’ level (transaction FSP0) and contains the information used by all company codes using this chart of accounts such as description, group account number etc.
Each company code using this chart will then add its own company code view (via transaction code FSS0) which contains localized data specific to that entity e.g. field status group, alternative account number etc.
The chart of accounts screen must be maintained before the local company code screens.
