RE:
As a design alternative, why not get rid of Default order settings and add all the Default order settings fields to Item Coverage (a new tab?) and permit distinction at Site level, Warehouse level and other dimension settings? Production and Transfer are already separate there. Now you can have Stops, different minimum order quantities at the Warehouse and also at the Variant level (etc.). Lead times are already on Item Coverage . . .
RE:
Hey Osman (fellow classmate ;)).I think what you are looking for is either the "import" operation in the auditing database or the "EditDataset". Are you using the REST admin APIS to get to the data? (https://learn.microsoft.com/en-us/rest/api/power-bi/admin/get-activity-events) Hope it works out for you. Cheers!
