Its datasource, its conditions and their order stay editable until the experiment is decided, inconclusive or archived. The datasource must be an active datasource of the company. Conditions may be incomplete in draft; from ready on they must be complete. ## OpenAPI ````yaml https://openapi.production.reelevant.io/v1/render/statistics put /experiments/{id}/datasource-assignment openapi: 3.0.0 info: title: statistics version: unknown description: >- # Errors | Error code | Message | HTTP status code | Payload | | :--- | :--- | :--- | :--- | | 9000,9001,9002,9003,9004,9006,9007,9008,9009,9010,9011,9012,9013,9014,9015,9016,9018,9019,9020,9021,9022,9023,9024,9025,9026,9027,9028,9029,9030,9031,9032,9033,9034,9035,9036,9037,9038,9039,9040,9043,9041,9042,9044,9045 | The experiment configuration is invalid | 422 | ```{"reason":"string"}``` | servers: - url: https://api.reelevant.com/v2/statistics/ description: production security: [] paths: /experiments/{id}/datasource-assignment: put: tags: - Experiments summary: Set the datasource-driven assignment of an experiment description: >- Adding it switches the experiment to datasource-driven assignment (draft or ready only).
