dates are not updating in sales order schedule line data

[kartik_abhyankar]

Dates in schedule line data shipping tab are not updating in sales order though availability check is blank in material master.

Also schedule lines are not confirming.

You have not shared enough information to assist you. When you say schedule lines are not confirming, it is not clear, why Availability Check is blank in material master. What is the Business Process ? Is that material not relevant for ATP ? Is that material not extended for MRP views ? Is that Service Material ?

Please share as much information as possible to show the right direction

MRP view is maintained with MRP Type ND, Material is trading material
