I could not replicate this in v21.11.95. Nor can I replicate it in v21.11.98 (the current version). I could not edit or delete in either version. @Davide, can you please be more specific? Which tabs? Which transaction types? What are you editing?
I can replicate the problem but only for sales invoices where I can change the custom fields values and an update would succeed. I do not have custom fields for anything else so those who have can check.
Update: so to replicate it just create a custom line field in sales invoice. Then create an invoice on an earlier date, then add a lock date. You can then open the invoice, change the value in the custom field and click Update. This change will be effected.
Sorry… I didn’t get how the new implementation works. It seems that Manager now monitors only some fields and not the whole form. Can ask that also descriptions (both the main and the column description) should be added to the monitored ones since in Italy are considered unchangeable part of the financial statement?
