i logged an issue (330108) at LCS and colleagues informed me to introduce this as new idea.

issue is, that the customer uses the rebate management-feature and as well projects, respectively have project-invoices.

unfortunately, the rebate-management-module is not supporting project invoices, whilst"normal" sales orders are reflected correctly.

I herewith strongly suggest to include them in the feature, at least by setting a boolean to define if to "include project invoices" or not, as soon as the source-type of the rebate deal is set to "invoice"

thank you,

Andreas
