I am using the below code to update the net price of the PO but it does not work. Any idea why? I noticed while looking at ME22N that the price field is disabled even in change mode, I can only change the price in ME22N by going to the services tab and changing the gross price.
The documentation of the bapi states
"Services and limits
Changes to existing items cannot be carried out with the Change method. It is only possible to create new items."
So I dont think this bapi can change the price of existing items through services. Below is the code im using and am unable to change the price. Please advice me on this.
