Retrieves maintenance sub types configured in the system, such as "Bearing Replacement" or "Belt Replacement" under a parent maintenance type like "Mechanical". 
All keys in `paramsDict` are optional and act as filters � omit a key (or pass an empty dict) to return every maintenance sub type. Combine filters (for example `maintenanceTypeId` and `enabled`) 
to narrow results to the sub types belonging to a specific maintenance type that are currently active.

### Parameters
**paramsDict** `Dictionary`<br />
<table class='dictionaryKeyTable'>
	<tbody>
 	<tr><td> - enabled</td><td>Boolean</td><td></td></tr>	
 	<tr><td> - maintenanceSubTypeId</td><td>Integer</td><td></td></tr>	
 	<tr><td> - maintenanceSubTypeName</td><td>String</td><td></td></tr>	
 	<tr><td> - maintenanceTypeId</td><td>Integer</td><td></td></tr>	
 	<tr><td> - maintenanceTypeName</td><td>String</td><td></td></tr>

### Returns
**workOrderStatusData** `pyDataset`<br />

### Example
```python
# Look up all enabled maintenance sub types under the "Corrective" maintenance type
paramsDict = {"maintenanceTypeName": "Corrective", "enabled": True}
data = system.kanoa.utilities.convertDatasetToJSON(system.kanoa.cmms.getMaintenanceSubTypes(paramsDict))

for i, row in enumerate(data):
	for k,v in row.items():
		print k,v
		
	break	#Just limiting to returning the columns from the first record for display purposes
