Total value in bid invitation

Dar SAP expert,

i have the following question, regarding online bidding scenario.

Purchaser adds expected price for each item in bid and then sends the bid invitation to suppliers.

When a supplier opens the bid invitation all items have 0 value and totale value is 0 too.

Is this the standars behavior? Shouldn't the vendors display the expected value entered in the bid by purchaser? (otherwise, what's the user of those prices??)

Thanks a lot and regards,

Ci
