Ever got into a situation where you had to list out child workflows and dataflows of a job? May be for documenting, or may be for checking object usages, Real challenge is when you have to represent it in organizational chart.
Here is an example:
For better view - click on the image, on the preview window, right click and save to desktop.
How do we do?
Of-course you can drill down every object in designer, navigate and draw chart in Microsoft Visio, MS-Word etc. But, how about generating hierarchical chart from repository metadata rather than drawing it?
Its just three steps away
1. Start by populating AL_PARENT_CHILD table, from designer or from command line,
a. From designer:
b. From command line using al_engine.exe
command: "%LINK_DIR%\bin\al_engine.exe" -NMicrosoft_SQL_Server -StestSQLhost -Udb_user -Pdb_pass -Qtestdb -ep
2. Login to repository database and execute the below query:
WITHCTEAS(
SELECT[PARENT_OBJ]
,[PARENT_OBJ_TYPE]
,[DESCEN_OBJ]
,[DESCEN_OBJ_TYPE]FROM[AL_PARENT_CHILD] PC
WHERE'JOB_CORD_BW_TD_OHS_POPULATE_SDL' = PARENT_OBJ
UNION ALL SELECTPC.[PARENT_OBJ]
,PC.[PARENT_OBJ_TYPE]
,PC.[DESCEN_OBJ]
,PC.[DESCEN_OBJ_TYPE]FROMCTE INNER JOIN [AL_PARENT_CHILD] PC ON CTE.DESCEN_OBJ=PC.PARENT_OBJ
) SELECT2ASID,[PARENT_OBJ] + '->' + [DESCEN_OBJ] CODEFROMCTE
WHEREPARENT_OBJ_TYPE IN ('Job','WorkFlow','DataFlow')
AND [DESCEN_OBJ_TYPE] IN ('Job','WorkFlow','DataFlow')UNION
SELECT1ASID, 'digraph a { node [shape=rectangle]'UNION
SELECT3ASID, '}'
From the output, copy only the contents in second column without header.
My data looks like this:
| digraph a { node [shape=rectangle] |

3. Open the webpage webgraphviz
- Clear the existing contents in text box
- Past the code you copied
- Click generate graph button and scroll down to see the generated graph.
That's all, Org chart of your job is ready !
Note:
- The given SQL query works only on MS-SQL Server.
- We are generating only parent child hierarchy, not the execution flow. i.e. two child node at same level may not execute in parallel.
- Since its not the execution flow, conditional workflows will not appear in chart.
- In the example shown, we were interested only in job, workflow & dataflow. You can modify the conditions to include other objects too.
- Webgraphviz is alternate for Graphviz tool which supports command line usage when installed.
