I have created a new confirmation control key where I have left the Tolerance too late and too early fields blank for both AB and LA categories. What I noticed is that the iDoc failed if the date is not the same as that on the PO for order confirmation. The same did not happen for ASN. Is that the standard SAP behaviour?
At the moment, I can only overcome the error on order confirmation by enter a value of 999.
Appreciate clarification of the standard SAP behaviour here.
