Retrieving the Regulatory Content for an Existing Revisable Regulatory Submission
To retrieve the regulatory content for an existing revisable regulatory submission, you must have Read permissions to the regulatory submission.
* 
The request returns an empty value, when:
• Regulatory content does not exist for the regulatory submission.
• Regulatory content of the specified category does not exist.
The following example shows you how to retrieve the regulatory content for an existing revisable regulatory submission. Use the following GET URI.
URI
GET /Windchill/servlet/odata/RegMstr/RegSubmission2('OR:com.ptc.qualitymanagement.regmstr.RegSubmission2:256705')/RegulatoryContent?$count=true
* 
For the revisable regulatory submission with associated regulatory content, the request returns the same regulatory content for:
• The checked-out version of the regulatory submission.
• A new iteration of the regulatory submission created when you check in its checked-out version.
• A new revision of the regulatory submission.
You can also retrieve the regulatory content of a specific category using $filter on category, as shown in the next example:
URI
GET /Windchill/servlet/odata/RegMstr/RegSubmission2('OR:com.ptc.qualitymanagement.regmstr.RegSubmission2:256705')/RegulatoryContent?$filter=Category eq 'ACKNOWLEDGEMENT1' &$count=true
Here, if regulatory content of the ACKNOWLEDGEMENT1 category does not exist, the request returns an empty value.
