Hi,
COPYLC is formula. This needs to be entered in the formula section of the business rules table. You do not have to define it in the R_ACCT. All you need in R_ACCT is a rate account to be associated with the business rule that has this formula.
Example: You could define a rate account STA (example) in R_ACCT and attach this STA to relevant accounts in the account dim. Define the business rule for STA and in formula, simply mention COPYLC.
Thanks,
