While answer is worth knowing from an OData perspective, there is also a pure CDS solution that works in every component that selects from CDS views, independent on whether they support annotations or not.įirst, you specify a CDS view as a SELECT FROM : 'MYCDSVIEW'ĭefine view MY_CDS_VIEW as select from MY_TABLE_FUNCTION on the involved CDS views and have the table function provide the CLIENT or MANDT columns explicitly. I haven't tried it but I have a feeling that performance would be better. Personally, I would go with the second option. The second way is to change your service's DPC class with your custom class, which inherits this standard class and do your custom logic in those redefined methods. A great deal of SAP ERP transactions run solely on ABAP code. "type": "YCDS_WITH_ABAP_CDS.YCDS_WITH_ABAPType" Armed with these ideas and sketches, Sharon asks the department data scientist (or SAP. METHOD if_sadl_exit_calc_element_read~get_calculation_info. Below are the steps used to create the database view in SAP ABAP: Step-1: Open the data dictionary initial screen by navigating the menu path or entering the transaction code SE11 in the command field. MOVE-CORRESPONDING lt_calculated_data TO ct_calculated_data. LOOP AT lt_calculated_data ASSIGNING FIELD-SYMBOL(). " do your extra logic and append/update your cds view data MOVE-CORRESPONDING it_original_data TO lt_calculated_data. " lt_calculated_data -> data that you will manipulate " it_original_data -> data that comes from cds Lt_calculated_data TYPE STANDARD TABLE OF ZV_TEST_ABAP. METHOD if_sadl_exit_calc_element_read~calculate. INTERFACES: if_sadl_exit_calc_element_read. Your abap class: CLASS ycl_cds_function DEFINITION Key 'ABAP:YCL_CDS_FUNCTION' //ycl_cds_function Earlier SAP CDS Views were only available in the SAP HANA environment but now CDS is also enabled in SAP NetWeaver AS ABAP allowing developers to work with ABAP programming tools in the ABAP layer while execution of the code is pushed down to the database (SAP CDS is fully. exposed as an Odata service, but not in transaction SE16N or the preview in Eclipse.ĭefine view YCDS_WITH_ABAP as select from sflight SAP CDS Views are of 2 types: HANA CDS Views and ABAP CDS views. This aligned with the strategic introduction of object-oriented ABAP programming in SAP ERP version 4.6C. The next iteration of the ALV framework was implemented using classes with names starting with CLGUIALV. ZI_PROD_FILTER_BYDATE = > is the actual CDS view which hits the database.NOTE: Your abap logic will only be executed when the CDS view is consumed by something that handles annotations i.e. The below figure shows an example of such a report in the BALVSD02GRID SAP demo program. “P_adeffdate” is the parameter in my example. Place this filter as a parameter in the final Consumption CDS view and pass it down all through your layers till it reaches the actual table selection.
