PLA_E_DCS_SINGLETON_REQUIRED
Some PLA modes require one collector because the result has a single producer
PLA_E_DCS_SINGLETON_REQUIRED means the Data Collector Set is configured for a mode whose semantics depend on exactly one contained IDataCollector. Zero collectors provide no producer, while multiple collectors make a single-output or collector-specific operation ambiguous.
Enumerate DataCollectors and verify both the collection count and collector types after XML import or template merging. Duplicate collectors can be introduced by retry logic that calls CreateDataCollector repeatedly. Remove the unintended object or split the work into separate sets instead of suppressing validation.
Object graph to verify
- Number of entries in IDataCollectorCollection.
- Collector type and Name for every entry.
- Template or XML source that added each collector.
- Whether the operation expects one output producer.
