We are a small to medium size business and our largest customer is required by their largest customer to be SAP certified. So as a result our customer is thinking that we have to be SAP certified. How far back on the manufacturing chain will this take us? Will we also be forced into this and expect our vendors to be SAP certified for this one customer that we have? How do we benefit from becoming SAP certified? You mention in your web site that it is probably not a need for a small to medium size business. Does this help in the manufacturing process in any way. This product is very expensive for us but we are just wondering.
