User Exits: Materials Mgmt. (Purchasing)
When goods are received with reference to a purchase order, the system checks the earliest delivery date against the GR date. The function exit of the enhancement MEFLD004 allows you to change the earliest delivery date and refuse to accept too-early deliveries, for example.
Whether or not the GR can be posted dependes on the attributes of the system message "Earliest possible delivery date is &" (message class M7, number 254). You specify in Customizing whether this is issued as an error or warning message or whether it does not appear at all.
