HiI'm struggling to find a way of quickly selecting promoted products within a promotion for pre and post promotion analysis within my SSAS cube.I have the following excerpt from my fact table:PK SalesRecordIDFK CustomerNoFK ProductCodeFK DateKeyPromotionNumber (line stamp from EPOS)QtySoldMy promotion table looks like:PK PromotionLineIDPromotionNumberFK ProductCodeDate Validity FromDate Validity ToA promotion is assigned a unique number and can have many products on it. A product can appear on more than one promotion and this is causing the problems.What I need is a way of selecting a promotional offer (and its products) to review it's performance pre and during the promotion. If I select only the transactions stamped with the offer number I lose the pre-promotional performance.I have tried referenced links but to no avail and named sets does not seem to be the correct solution for over 1000 promotions?Any help would be greatly appreciated!ThanksAdrian
