我在网上找到了一段代码来获取我需要的大部分内容，除了我还在寻找每个 VA 报告使用的 SAS 表名称。有没有办法使用数据步骤函数来写入元数据来做到这一点？
data MDIDs;
length Server_Uri rp_uri Metadata_ID Name _Name TypeName Path Location _Location MetadataCreated MetadataUpdated CreatedBy ModifiedBy $256;
length Created Modified 8.;
format Created Modified datetime19.;
nobj = 1;
n=1;
call missing(Metadata_ID, _Name, MetadataCreated, MetadataUpdated, Created, Modified, TypeName, Path, Server_Uri, _location, CreatedBy, ModifiedBy);
do while(n le nobj);
nobj=metadata_getnobj("omsobj:Transformation?@PublicType = 'Report.BI'",n,Server_Uri);
rc=metadata_getattr(Server_Uri,'Id',Metadata_ID);
rc=metadata_getattr(Server_Uri,'Name',_Name);
rc=metadata_getattr(Server_Uri,"MetadataCreated",MetadataCreated);
rc=metadata_getattr(Server_Uri,"MetadataUpdated",MetadataUpdated);
name=translate(translate(translate(translate(_name,"-","–"),"£","£"),"%","%"),"+","+");
Created=input(MetadataCreated,anydtdtm.);
Modified=input(MetadataUpdated,anydtdtm.);
rc=metadata_getattr(Server_Uri,"PublicType",TypeName);
numrp=metadata_getnasn(Server_Uri,"ResponsibleParties",1,rp_uri);
if numrp>0 then do;
numrp=metadata_getnasn(Server_Uri,"ResponsibleParties",1,rp_uri);
rc=metadata_getattr(rp_uri,"name",CreatedBy);
numrp=metadata_getnasn(Server_Uri,"ResponsibleParties",2,rp_uri);
rc=metadata_getattr(rp_uri,"name",ModifiedBy);
end;
TreesCount=metadata_getnasn(Server_Uri,"Trees",1,Server_Uri);
rc=metadata_getattr(Server_Uri,"Name",Path);
_tree=1;
do while (_tree>0);
_tree=metadata_getnasn(Server_Uri,"ParentTree",1,Server_Uri);
if _tree > 0 then do;
_rc=metadata_getattr(Server_Uri,"Name",_location);
Path=catx('/',_location,Path);
end;
end;
Location = '/'||Path;
output;
n=n+1;
end;
keep Metadata_ID Name TypeName Location Created Modified CreatedBy ModifiedBy;
run;
如有任何帮助，我们将不胜感激。谢谢！
根据您的版本，有两种方法可以执行此操作。 SAS 9.4 使用元数据服务器并使用 SAS 进行解析，而 SAS Viya 使用 API。
元数据服务器不会告诉您 VA 报告在 SAS 9.4 中使用哪些数据，但您可以提取报告 XML 并解析它以查找所有数据源。当您从元数据服务器上的报告文件中提取内容时，您将获得 XML。
所有数据源都属于
<DataSources><DataSources>
<DataSource label="CARS" type="relational" name="ds7">
<InMemoryResource resourceName="SBIP://METASERVER/Shared Data/LASR/AUTOLOAD/CARS(table)" label="AUTOLOAD.CARS"/>
<BusinessItemFolder>
...
</BusinessItemFolder>
</DataSource>
<DataSource label="CLASS" type="relational" name="ds19">
<InMemoryResource resourceName="SBIP://METASERVER/Shared Data/LASR/AUTOLOAD/CLASS(Table)" label="AUTOLOAD.CLASS"/>
<BusinessItemFolder>
...
</BusinessItemFolder>
</DataSource>
</DataSources>
您可以使用 SAS 提取它。
data want;
infile "/path/to/file/report.xml" lrecl=32676 length=len;
input line $varying32767. len;
if(find(upcase(line), '<DATASOURCE LABEL='));
table = scan(line, 2, '"');
drop line;
run;

您可以使用 Viya REST API 获取报告 XML 并以类似的方式解析它。唯一的区别是您还需要获取 CASLIB。您将需要报告 URI，您可以从 SAS Drive 或通过复制报告链接来获取该 URI。 URI 看起来像 GUID，如下所示：
fc0331a6-311h-4267-84d8-512ec2ff375d您可以通过转至报告服务的
/contenthttps://myviyaserver.com/reports/reports/fc0331a6-311h-4267-84d8-512ec2ff375d/content如果您想按名称查找系统上的每个报告 URI，您可以通过转到
/reports/reports/?limit=999999https://myviyaserver.com/reports/reportsJSON 输出

您可以使用
PROC HTTP在 SAS Studio 中完成这一切，并对数据步骤进行少量更改。
filename resp temp;
proc http
url="https://%scan(&_baseurl, -2, /)/reports/reports/fc0331a6-311h-4267-84d8-512ec2ff375d/content"
out=resp
method='get'
oauth_bearer=SAS_SERVICES;
run;
data want;
infile resp lrecl=32676 length=len;
input line $varying32767. len;
if(find(upcase(line), '<CASRESOURCE'));
caslib = scan(line, 4, '"');
table = scan(line, 6, '"');
keep caslib table;
run;
循环查看 Viya 中的每个 Visual Analytics 报告并获取数据源这是浏览报告列表并获取其数据，然后将其保存到单个文件的完整代码。
