The normal behavior of entrée Invoicing is to lock down the "Invoice Date" after any items have been added to the invoice. The date is also locked down after the Standard Order list has been loaded. The reason for this restriction is that in both cases decisions will have been made about these items based on the current Invoice Date. For instance, a promotion may start or end on the current date and changing the date one day either way might activate or desctivate the promotion. If you're using Bid Pricing or Future Pricing the same one day change might result in receiving a very different price. The problem is that, due to the processing time involved, decisions about pricing and promotions have to be made ahead of time so they are not reviewed once the item has been added to the invoice.

 

Standard Order is very similar in that the Unit Price of each item is calculated during loading of the Standard Order list and those prices are not reviewed afterwards so the correct Invoice Date needs to be set before the list is loaded.

 

Some distributors have expressed a desire to be able to change Invoice Date and ignore the issues that are created with the date-sensitive features of the system and this System Option provides that option for those who require it..
