Defining Data Fields for Calling
Create BAPI
Wrapper 
In addition to the back-end application data that must be downloaded and displayed for clients, you must define the data fields to be uploaded from the mobile device to the server. This only applies to the synchronization types 2-Way (S01), Timed 2-Way (T01) and Back-End-Driven (T51). All the fields mapped to be uploaded are used for the synchronization type Upload (U01), since there is no data to be downloaded in this case.

1. Start transaction merep_sbuilder.
2. Enter the SyncBO ID.
3.
Choose
Edit.
Alternatively, choose
Mapping and go to the SyncBO Builder:Mapping
Setting screen by double-clicking on either Import or Tables
under the Create BAPI Wrapper name.
Choose
Display <-> Change.
4. On the Import tab page on the Mapping Setting screen, select Map to map the fields in the header structure in which the value of a client application can be provided.

Only some of the fields of the header structure (fields that were mapped in the parameter GetList tables) can be mapped if the synchronization type is not Upload (U01).
5. On the Import tab page, select Mandatory to define any mandatory fields.
6. On the Tables tab page, select Map to map the fields in the header structure for which the value is provided by a client application.

Only some of the fields of the item structure (fields that were mapped in the parameter GetList tables) can be mapped if the synchronization type is not Upload (U01).
7. On the Tables tab page, select Mandatory to define any mandatory fields.
8. Perform the steps described in Defining the Use of Default Values to define any required default values for the fields on the Import tab.
9. If the synchronization type of the SyncBO is Upload (U01), perform the steps described in Defining SyncBO Relationships to define the field containing a key field value of another SyncBO (if applicable on the Import/Tables tab page).

If the synchronization type of the SyncBO is Upload (U01), the header and item structures of the SyncBO are defined when mapping for Create BAPI Wrapper.

The RelatedSyncBO column on the Import/Tables tab page is only selected if the synchronization type is Upload (U01).
