Urgent - multiprovider/modeling questions

Question

i have a scenario where i have an ODS containing all vendors for a given article-site relationship, and there's a flag in there indicating which one of the vendors is fixed.
i also have an infocube that contains material movement data, which has the article and the site, but no vendor.
now i'd like to be able to create a web query that tells me the movement data for a given article and site, that will also gives me the fixed vendor for the article-site combination. how should i go about it? i've tried a multiprovider, but it doesn't seem to work that way.

Answer 1

thanks for the suggestion - but if i were going to use an ODS for material movements already, wouldn't it be easier if i did it this way:
when the material movements data is loaded into an ODS, create an update rule from the article-vendor-site relationship to the ODS (data mart interface) and supply the fixed vendor for each entry of the material movements data. after which load the material movements ODS into an infocube.
i understand this involves some degree of "brute-force"-edness, since i'd have to do direct table updates, but it would work. would this then be a better solution than the one you've proposed?
one other alternative i was thinking about (but will probably encounter problems with) would be creating the material movements cube as is, but then create another update rule from the article-vendor-site ODS into it which will update the vendor characteristic - is that going to work? i imagine that if it would, i'd have difficulties with it since cubes have SIDs to be reckoned with.
if we do push ahead with the 2 ODS and infoset, how do i create a query on it then?
hoping for your feedback - thanks. =)
