FDM enables target-account or target-entity derivation by permitting the placement of wildcard characters (* and ?) in both source and target members. Mapping-table records that have wildcard characters in both the source and target column are considered to be Automap.
The criteria for the Automap entry (Like 0011??) retrieves the first three records from the general ledger trial balance. Because the Automap entry contains wildcard characters in the target account column, FDM must search the source account to replace the wildcard characters within the target account with actual characters from the source account.
The source-account characters represented by the two hyphens (under Rule Name) are used to replace the two question marks that follow Cash (under Target Account). Next, FDM verifies that the new target accounts (Cash.00, Cash.01, Cash.16) are valid target accounts. If the accounts are valid, the derived values are assigned to the trial balance as the target account values.
