Can we use F4201Z1/F4211Z1 to Update existing and also Add new Line Items in Sales Order

Hi Mentors,

I have a requirement to update the existing line items in Sales order like price and create new line item eg: Tax Line Items and Freight Line items on existing Sales Order at a certain Status (NXTR=806 in our case.)

Currently users manually do this activity to update the price and insert new line Items one by one and we are trying to automate this step.

With what i have researched and got to know this can be achieved using our Z process F4201Z1 and F4211Z1 and use TNAC="A" or "02" for ADD / "04" or "U" for Change.
