Updating the Line items date based on header delivery date in ERP sales order

Hi Gurus,

I have a requirement in CRM Web UI ERP sales order, when I change the Request. Deliv. Date in the header of a sales order and save it, the Request. Deliv. Date of the line items also needs to be updated based on the header date.

I checked the view - ERP_H/HeaderDetail, context node-ERPADMINH and attribute STRUCT.KEDAT.

There are GET and SET methods How do we use these to implement the logic?

Please let me know how do we use these methods.

Regards,

Gopi.
