ABAP字典类型的DDL source Z1127ExtView无法转换为Extend（->；长文本）

我有表格

Z1127\u学生

：

define table z1127_student {
  key id     : z1127_sample not null;
  branch     : z1127_sample1;
  age        : z1127_age;
  address    : z1127_address;
  percentage : z1127_percent;
}

@AbapCatalog.sqlViewName: 'Z1127_CDSVIEWS'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'CDS VIEWS'
define view Z1127_CDS_VIEWS as select from z1127_student
{
key id,
branch,
age
} 

@AbapCatalog.sqlViewAppendName: 'Z1127_SQL_3'
@EndUserText.label: 'cds view 3'

extend view Z1127_CDS_VIEWS with z1127_cds3 {

    address, 
    percentage
}

（列的类型基于类型

int2

和

char

）

和CD视图

Z1127\u CD\u视图

：

define table z1127_student {
  key id     : z1127_sample not null;
  branch     : z1127_sample1;
  age        : z1127_age;
  address    : z1127_address;
  percentage : z1127_percent;
}

@AbapCatalog.sqlViewName: 'Z1127_CDSVIEWS'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'CDS VIEWS'
define view Z1127_CDS_VIEWS as select from z1127_student
{
key id,
branch,
age
} 

@AbapCatalog.sqlViewAppendName: 'Z1127_SQL_3'
@EndUserText.label: 'cds view 3'

extend view Z1127_CDS_VIEWS with z1127_cds3 {

    address, 
    percentage
}

我尝试创建此扩展视图：

define table z1127_student {
  key id     : z1127_sample not null;
  branch     : z1127_sample1;
  age        : z1127_age;
  address    : z1127_address;
  percentage : z1127_percent;
}

@AbapCatalog.sqlViewName: 'Z1127_CDSVIEWS'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'CDS VIEWS'
define view Z1127_CDS_VIEWS as select from z1127_student
{
key id,
branch,
age
} 

@AbapCatalog.sqlViewAppendName: 'Z1127_SQL_3'
@EndUserText.label: 'cds view 3'

extend view Z1127_CDS_VIEWS with z1127_cds3 {

    address, 
    percentage
}

但它显示了这个错误：

ABAP字典类型的DDL源Z1127CDS3无法转换为扩展（->长文本）

如何避免此错误？

是否尝试对视图扩展进行注释？表和Z1127_CD_视图成功激活？i注释扩展视图。Z1127_CDS_视图成功激活错误仅显示在扩展视图中。我使用和重新创建了配置，视图和扩展完全相同，我的扩展成功激活。我相信问题在于您的表Z数据元素。我故意没有指定表增强类别来准确地再现您的案例，所以enh.cat。这里的重点不是你有什么ABAP版本吗？
