Implementing /IWBEP/IF_MGW_EDP_MAP_CREATE for Create and Deep Insert — Inbound Mapping
The Inbound mapping method is provided with:
BOP DO
A set of BOP DOs processed by previous mapping specialists
The entity data (ER_ENTITY or ER_ENTITYSET or ER_DATA). The entity data can be partially filled by previous mapping specialists.
Operation specific parameters
To implement inbound mapping interface method /IWBEP/IF_MGW_BOP_MAP_CREATE~MAP_INBOUND for Create and Deep Insert operations, proceed as follows:
The input parameter IO_DATA_PROVIDER (of type /IWBEP/IF_MGW_ENTRY_PROVIDER) contains the input request. IT_KEY_TAB contains the keys of an entity.
Read the request data into a local variable.
Create the BOP request using the input request.
Set the BOP DO request.

Implementing /IWBEP/IF_MGW_EDP_MAP_CREATE for Create and Deep Insert — Outbound Mapping
To implement outbound mapping interface method /IWBEP/IF_MGW_BOP_MAP_CREATE~MAP_OUTBOUND for Create and Deep Insert operations, proceed as follows:
Get the BOP response.
Check if there are any errors from the response. If yes, add the messages to the Message Counter.
For Create operation, form the response data.
