Hi, In ecommerce component in R4 an error message occured, when product has wrong configuration. For example: PC001 is "Fixed Asset Usage", but in "Rental" tab is field "Max.Nbr. of Persons for rental" empty. It is configured here (sorry :-) ): http://demo40.hotwaxmedia.com/ecommerce/control/product?product_id=PC001
IMHO, its bug. I expected some error or warning message in this case. Thanks Jan Valkovic
