Technical Details

In the past, contributions were associated with quotations using a pivot table called civicase_sales_order_contribution. However, in this pull request, we have implemented a new approach by utilizing custom fields called Case_Opportunity and Quotation on the contribution. This allows for more flexibility in linking contributions to either a case or a quotation as needed.

The new custom fields belong to a new custom group CustomGroup_Opportunity_Details that extends the Contribution entity and will be added on the extension install or cache clear if it doesn't already exist.

Also, we have recreated the Quotation invoice screen so it is generated from the Contribution entity instead of CaseSalesOrderContribution entity

Comment

• The CaseSalesOrderContribution entity will be removed in a subsequent PR.
• Some of the invoices' bulk action is not working, this is reproducible on other CiviCRM 5.51.3 sites
