Hello,
Basically, we are using Syteline version 2019.
If we modify some master data such as tax code description, company name, my historical invoices will be modified as well.
On my knowledge and by default, an ERP should not modify any historical documents.
Could you please confirm that Systeline has this standard behavior, which means, the customization of the invoice template was not correctly and Systeline should not behave like that.
Thanks in advance
