Gateway Service Create with Multiple Line Items

[Former Member]

Hello,

I observed that you can create an entity in gateway with only a Flat structure, no nested structure or a structure with an internal table is not supported. As i have a requirement of creating a purchase order with multiple items through a create call in gateway service.how do i achieve this.Can any one provide me some direction.

For update of several entities, you need to use $batch.

Kaushik,

In your case Purchase Order header will be an Entity and Purchase Order Line item another entity. You define relationship between them using Associations and Referential Constraints.

For fetching both at a time, you need to use a '$expand'. For creating both at a time, you use 'Deep Insert'.

I would suggest you to go through odata.org and search these concepts.

Also you can read more here.
