To add a chained operation to a mobile business object (MBO), the MBO must meet these requirements:
- Be bound to a data source that has a primary key, and has one or more Find by attributes set.
- The record set returned by the chained read operation must have all columns mapped to key attributes (Find by attributes). You can map these either when you create the chained operation, or by editing the operation in the Properties view.
- The result set of the chained operation must contain all MBO playback and sync parameters (Filter by parameters and attributes).
