Hi:
This makes much more sense. It says right in the description of the dimension (this sounds like an OLAP cube) that
BDC – The Class, Size, and Flavor combined. Example: 012/021/034 – Ruffles/Supersize/Salsa ‘n Cheese.
So however they derived the abbreviated term, to me, it seems to me that they mean something like:
Brand/Class (Ruffles)
Dimension/Size (Supersize)
Characteristics/Flavor (Salsa 'n Cheese)
It also looks like they have a separate Class item and a separate Size item -- but they do not show a separate Flavor item. It might have made more sense if they had made the abbreviation CSF (class/size/flavor) but perhaps that abbreviation was already in use for something else. This sounds like a company-specific term, unrelated to any of the "BDC" possibilities listed above.
In one of your original posts, you said that
this question i.e " improved 1.5%sas forecast accuracy at BDC level of food bevarage industry?".
BDC, in this context, seems to mean a combined variable or code for CLASS, SIZE and FLAVOR combined -- if that knowledge doesn't help you with the original question, then you need to go back to WHERE the question is. If the question is in a text book or a case study, then you should ask your professor to clarify the question. If this is a practice question on one of the SAS certification exams, then you should send mail to the certification folks
http://support.sas.com/certify/contact.html
and ask for more clarification -- they can contact one of the instructors or developers who worked on the exam and find out more pertinent information.
By the way, pictures or images do not post to the forum. So, there was no picture or diagram posted here. If you contact the certification folks for more help, it would be most useful for them to know EXACTLY which exam, which practice module or which question number you need help with. The full text of the question, and/or the page number would probably help as well.
If this is a 3rd party preparation guide or a textbook, you would have to go to those authors for clarification. Is this a SAS publication that you have questions about? Is this a SAS exam or a SAS SPEL (self-paced e-learning) module or a SAS preparation guide that you have a question about??? If this is a white paper by SAS authors or something in the documentation, then you could contact Tech Support for help.
