First Query your requirements and then consider that you have many organizations and more will be added later on stages. So you cannot go manually touch your design and add up the extra columns , this will hike up your work process. You can neglect it by following a simple method in BI Publisher.
First Draw up your table using the Wizard
Then insert a column to the right and insert the organization field in between the for loop
Now double click on For loop (OU) and edit your xml from normal group to Group_name;Column_name
Eg: <? for-each-grp:G_ORG;ORG ?>
And End it as
<?end for-each-grp?>
After altering your xml script , you will finally get the output of OU column parallel format dynamically.
