How to read the data of CDS view association with ABAP
tags: ABAP CRM Original SAP technical article by Jerry Wang
AG3, view name Zorder_Sys_Status.
This view has an association named _statushelp:
Requirement
I would like to read the guid from host view Zorder_Sys_Status together with its associated data via association _statushelp.
(1) Since there is no existing data type which holds both host view field and associated view fields, you have to create one on your own:
(2) Use the following syntax in ABAP code:
DATA: lt_data TYPE tt_Data.
SELECT
guid,
\_STATUSHELP-STATUS_KEY AS STATUS_KEY ,
\_STATUSHELP-STATUS_TEXT AS STATUS_TEXT
FROM
ZORDER_SYS_STATUS
WHERE
ZORDER_SYS_STATUS~GUID = 'FA163E8EAB031EE6A99F824537D112A4' AND ZORDER_SYS_STATUS~STAT = 'I1002' AND \_STATUSHELP-STATUS_KEY IS NOT NULL
INTO TABLE @lt_data.
By the way, when the association defined in CDS view is consumed via OPEN SQL, it will be converted to LEFT OUTER JOIN, as could be observed in SQL trace:
In ST05, select your trace record, and click this button in toolbar:
