Delivery Date Not getting Updated in Me22n

Hi,

We are creating some Load and Go STO. With one line item having delivery Date X.

Then We insert a new Line Item with Delivery Date Y.

THe initial Line item has its deletion INdicator Set.

But when we Check for this New Line Item Material and Plant in MD04 , it is still showing us the Delivery date X and Not Y.

Inputs Appreciated.

Thanks

Gaurav
