Proc Metadata to get Dependent Objects

yashpande — Mon, 06 Jun 2016 03:55:35 GMT

Hi There,

We have got SAS DI Jobs and I am trying to findout all list of SAS Jobs present in repository and its inputs and Outputs tables.

I have heard a lot about PROC Metadata and have gone through the SAS Docs , however I couldnot find the information on looping through the entire repository.Some direction to the approach would be really appreiated.

This below code is using data step metadata function.

Note -

nobj = metadata_getnobj("omsobj:Job?@Name contains ''", n, job_uri);

It would run for all jobs in foundation repository. In case you want to test for a particular job then update the statement as shown below

nobj = metadata_getnobj("omsobj:Job?@Name contains ''<Jobname without .sas >", n, job_uri);

How about using the sas-relationship-reporter. Have a look at this blog entry http://blogs.sas.com/content/sgf/2015/03/04/relationships-are-easy-for-sas-objects/

More details on the relationship reporting tool can be found here http://support.sas.com/documentation/cdl/en/bisag/68240/HTML/default/viewer.htm#p1dcleibglhr6wn19yzvfz81yw5y.htm

Can we also add the column names in this report for each transformation ? E.g. Extract has 10 columns and also has new derived variable in output and I want to display that details as well. Need some guidance on this

Re: Proc Metadata to get Dependent Objects

I have added a small loop to add TRANSFORMATION target table column name.

Source table column name not included yet as it will make the output dataset more bulky.

col_cnt=0;
do while(col_cnt <rc_cols);
col_cnt=col_cnt+1;
tgt_col_uri=""; tgt_col_nm="";
rc = metadata_getnasn(tgt_uri, 'Columns',col_cnt, tgt_col_uri);
rc = metadata_getattr(tgt_col_uri, 'Name',tgt_col_nm);
output;

This is perfect. However can you also help me in the report having source columns as well ? doesnt matter size of dataset
