MIS Report Partner Details

This module extends MIS Reports (from the mis_builder app) so that a KPI line can be expanded into one detail row per partner and account. In the KPI configuration form, a new checkbox 'Show Details by Partner' appears; when ticked, you can also choose a style for the detail rows and tick 'Add VAT columns' to display the partner's VAT country and number next to the description.

When a report is computed, the module looks at the KPI's expression, finds the partners and accounts that have balances for the selected periods, and creates a sub-KPI for each combination. These sub-KPIs are shown as indented detail rows under the parent KPI, with the description formatted as 'account → partner'. Rows with zero balance in all columns are removed automatically. The drilldown from a partner detail row opens the underlying journal items filtered by that partner and account, and the action title includes the partner name and VAT.

The module works with receivable and payable account types and uses the report's move line source (for example account.move.line). It also adds a small JavaScript component that inserts VAT country and VAT number columns into the report table when the option is enabled. No new menus are added; the feature is configured directly in the existing MIS Report KPI form.
