Report Metadata - Using Metadata as Parameters

Hi,
Could you tell me how I should use report metadata as parameters?
I tried all possible combinations and it didn't work - metadata entries were unknown for query.
The documentation it is not clear in point https://reportserver.net/en/guides/admi … -Metadata/ (6.3.11)

What should I write in Report Metadata?
_RS_METADATA_MYPARAM - where MYPARAM is name, so I understand I have to save in Report Metadata tab: _RS_METADATA_guid with my value. Or maybe just _guid or guid?
Then how to use it in a query? ${_RS_METADATA_guid} or ${guid} or &{_guid} ?

Could you give me a simple example which should work?

P.S. I want to have a parameter to use in query which value I can set in each report variant so I wanted to use Report Metadata for that...Any other idea?

Re: Report Metadata - Using Metadata as Parameters

Hi Patryx,

this should work:
select ${_RS_METADATA_myMetadataKey} as abc, *  from mytable

You should see the myMetadataKey values if you previously define a metadata with name: "myMetadataKey".
The "execute" button in the query is not working in this case, I raised ticket RS-3505 for this. But other than this, this seems to work.

What exactly doesn't work in your case? Please post some screenshots.

Eduardo

Re: Report Metadata - Using Metadata as Parameters

Hi Eduardo,
I tested your example and you are right, button Execute of query doesn't work, but when I execute report in Report Execution View it works and read the variable.

BUT the problem is with Metadata Datsource when I test it in Metadata Datasource Query and there unfortunately it doesn't work at all.
I mean even in Report Execution View nor by button Execute for query.

When I try to execute a report I get "Cannot find property _RS_METADATA_test" in window.
Could you check it if you have the same error?

Re: Report Metadata - Using Metadata as Parameters

Hi Patryx,

the "execute" buttons are working now when you include report metadata in their query.

Re: Report Metadata - Using Metadata as Parameters

Hi,
To continue this topic, we noticed that ${_RS_METADATA_SUPER_myMetadataKey} didn't work at all.
I created report and added metadata 'myMetadataKey' with value 'test report'). Then I created variant of this report and added there metadata 'myMetadataKey' with value 'test variant'.

Unfortunately I see only 'test report' in both case: when I execute report and variant...Could you check it? It seems that it can't see the overwritten metadata in variant.

What's interesting if I delete from report metadata key 'myMetadataKey' and I have in variant metadata 'myMetadataKey' with value 'test report' and use parameter as ${_RS_METADATA_myMetadataKey}, it works for executing variant report (error for execute base report).

Please tell me how to resolve it

Re: Report Metadata - Using Metadata as Parameters

Hi Patryx,

if you use ${_RS_METADATA_SUPER_myMetadataKey}, you will see in both cases the "SUPER"-value. In the variant case, you will see the report value. In the report case, the same (there is no parent of a report). So this is the correct behavior. If you want to see different values use the normal ${_RS_METADATA_myMetadataKey}. In the variant case you will see the variant value, in the report case you will see the report value.

Eduardo

Re: Report Metadata - Using Metadata as Parameters

Hi Eduardo,
This still doesn't work ${_RS_METADATA_SUPER_myMetadataKey} if I name a key in variant as "myMetadataKey" and try to execute query from administration.

Sorry, you're right. It seems to be OK.
