When trying to make a nominal account inactive, the system runs several background checks. Check the following to identify the reason for the error:
Is the nominal account used in a Nominal Category?
Is it used as a Year End Update account?
Is it used as a Currency Year End Update account?
Are there any batched nominal transactions using this nominal code?
Are there any uncompleted recurring journals using this nominal code?
Are there any Sales Analysis codes using this nominal code?
Are there any Purchase Analysis codes using this nominal code?
If all of the above have been checked and the cause cannot be found, contact support. See Get support in Dimensions.
