Requirement

The following mapping logic needs to be implemented in CDS view layer:
if MARA-MTART = “SERV”, then PRODUCT_TYPE = “02”
if MARA-MTART <> “SERV” and PROD_TYPE_CODE = ‘2’, then PRODUCT_TYPE = “02”
otherwise PRODUCT_TYPE = ''01".
View source code:

@AbapCatalog.sqlViewName: 'ZMATTYPE' @AbapCatalog.compiler.compareFilter: true @AccessControl.authorizationCheck: #CHECK @EndUserText.label: 'material type' define view Zmaterial_Type as select from mara inner join t134 on mara.mtart = t134.mtart {key mara.scm_matid_guid16 as product_guid,case when ( mara.mtart = 'SERV') or t134.prod_type_code = '2'then '02'else '01'end as product_type }
