How Do Changes Take Effect?

The sample account and the data transfer rules take effect when you create a G/L account master record in the company code. The most current sample account and rules always apply. After the master record is created, the sample account no longer has an effect. However, changes to the rules continue to have an effect on the master record. The current rule type is always the valid one.

This is necessary since you may have transferred data from the sample account as fixed data. If you have made a mistake, you revise the rule and then change the transferred data.
