To advance the Nominal Ledger Period, you must lock certain modules.
If you advance the Nominal Ledger, you must prevent access to the following relevant modules, which are linked to the NL Company being closed:
MS - Manufacturer Systems, if using Purchase Invoice Verification (that is, paperless invoicing)
Example 1: If the system is set up with individual companies, you need to prevent access to Co 01 in all the above modules when closing NL Co 01. And, if closing Co 02, access needs to be prevented to Co 02 in the above modules only.
Example 2: If divisionalised, all divisions, that Nominal Ledger needs to have the above modules locked. Closing NL Co 00, you have SL/PL/AR/AJ companies 01, 02, and 03, which all post into NL Co 00. Access then needs to be prevented to all three companies in these modules.
These are all modules where day-books can be printed live and can therefore try to post entries while the period is being closed.
If necessary, check the company mapping to determine whether the Nominal Ledger company in question has multiple modules/companies mapped to it. More than one Sales Ledger, Purchase Ledger company, and so on, can be mapped to one Nominal Ledger company. Access must also be prevented to all these modules/companies as well.
Note: Modules with the same company numbers do not show in company mapping, but, by default, will automatically be linked unless re-pointed to another Nominal Ledger company.
