It's not a setting but rather some default behavior that Accounts applies to automatically filter reports based on the selection. You'll have a criterion in your report for INVOICE.INVOICE_NUMBER (possibly a disabled one) and it is this that triggers the automatic filtering. Remove that criterion and your report should return the same thing regardless of selection in the invoices ledger.

Hope that helps

Wow - that was amazingly quick.  Many thanks  -  I would never have spotted that as the solution.

All working as I wanted now.

I think its a feature
