2 - Semantic Model Operations
Get Model Information
# Check if model exists
fab exists "ws.Workspace/Model.SemanticModel"
# Get model properties
fab get "ws.Workspace/Model.SemanticModel"
# Get model ID (needed for Power BI API calls)
fab get "ws.Workspace/Model.SemanticModel" -q "id"
# Get full definition (TMDL)
fab get "ws.Workspace/Model.SemanticModel" -q "definition"
Export Model
# Export to local directory (PBIP format with TMDL)
fab export "ws.Workspace/Model.SemanticModel" -o ./exports -f
Creates folder structure:
Model.SemanticModel/
├── .platform
├── definition.pbism
└── definition/
├── model.tmdl
├── tables/
│ ├── Sales.tmdl
│ └── Date.tmdl
└── relationships.tmdl
Import/Update Model
# Import from PBIP folder
fab import "ws.Workspace/Model.SemanticModel" -i ./exports/Model.SemanticModel -f
# Copy between workspaces
fab cp "Dev.Workspace/Model.SemanticModel" "Prod.Workspace/Model.SemanticModel" -f
3 - Refresh Operations
Trigger Refresh
# Get IDs
WS_ID=$(fab get "ws.Workspace" -q "id" | tr -d '"')
MODEL_ID=$(fab get "ws.Workspace/Model.SemanticModel" -q "id" | tr -d '"')
# Trigger full refresh
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes" -X post -i '{"type":"Full"}'
# Check refresh status
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes?\$top=1"
Enhanced Refresh (Partition-Level)
# Refresh specific tables
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes" -X post -i '{
"type": "Full",
"commitMode": "transactional",
"objects": [
{"table": "Sales"},
{"table": "Inventory"}
]
}'
# Refresh with retry
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes" -X post -i '{
"type": "Full",
"retryCount": 3
}'
Refresh Schedule
# Get current schedule
fab api -A powerbi "datasets/$MODEL_ID/refreshSchedule"
# Set daily refresh at 6 AM UTC
fab api -A powerbi "datasets/$MODEL_ID/refreshSchedule" -X patch -i '{
"enabled": true,
"days": ["Monday","Tuesday","Wednesday","Thursday","Friday"],
"times": ["06:00"],
"localTimeZoneId": "UTC"
}'
Troubleshoot Refresh Failures
# Get refresh history
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes"
# Common failure patterns:
# - "credentials" → Update data source credentials
# - "gateway" → Check gateway status
# - "timeout" → Use enhanced refresh with smaller batches
# - "memory" → Optimize model or use incremental refresh
4 - DAX Query Execution
Execute DAX queries against semantic models:
MODEL_ID=$(fab get "ws.Workspace/Model.SemanticModel" -q "id" | tr -d '"')
# Simple query
fab api -A powerbi "datasets/$MODEL_ID/executeQueries" -X post -i '{
"queries": [{"query": "EVALUATE VALUES(Date[Year])"}]
}'
# Aggregation query
fab api -A powerbi "datasets/$MODEL_ID/executeQueries" -X post -i '{
"queries": [{
"query": "EVALUATE SUMMARIZECOLUMNS(Date[Year], \"Total\", SUM(Sales[Amount]))"
}]
}'
# TOPN query
fab api -A powerbi "datasets/$MODEL_ID/executeQueries" -X post -i '{
"queries": [{
"query": "EVALUATE TOPN(10, Product, [Total Sales], DESC)"
}]
}'
# Query with parameters
fab api -A powerbi "datasets/$MODEL_ID/executeQueries" -X post -i '{
"queries": [{
"query": "EVALUATE FILTER(Sales, Sales[Year] = @Year)",
"parameters": [{"name": "@Year", "value": "2024"}]
}]
}'
5 - Report Operations
Get Report Info
# Check exists
fab exists "ws.Workspace/Report.Report"
# Get properties
fab get "ws.Workspace/Report.Report"
# Get connected model
fab get "ws.Workspace/Report.Report" -q "definition.parts[?contains(path, 'definition.pbir')].payload | [0]"
Export Report
# Export to PBIP format
fab export "ws.Workspace/Report.Report" -o ./exports -f
Clone Report
# Copy within workspace
fab cp "ws.Workspace/Report.Report" "ws.Workspace/ReportCopy.Report" -f
# Copy to another workspace
fab cp "Dev.Workspace/Report.Report" "Prod.Workspace/Report.Report" -f
Rebind Report to Different Model
WS_ID=$(fab get "ws.Workspace" -q "id" | tr -d '"')
REPORT_ID=$(fab get "ws.Workspace/Report.Report" -q "id" | tr -d '"')
NEW_MODEL_ID=$(fab get "ws.Workspace/NewModel.SemanticModel" -q "id" | tr -d '"')
fab api -A powerbi "groups/$WS_ID/reports/$REPORT_ID/Rebind" -X post -i "{
\"datasetId\": \"$NEW_MODEL_ID\"
}"
Export Report to File (PDF/PPTX)
# Export to PDF
fab api -A powerbi "groups/$WS_ID/reports/$REPORT_ID/ExportTo" -X post -i '{
"format": "PDF"
}'
# Poll for completion, then download
6 - Gateway Operations
List Gateways
# Tenant-level gateways (hidden entity)
fab ls .gateways
# Get gateway details
fab get ".gateways/MyGateway.Gateway"
Data Source Management
GATEWAY_ID=$(fab get ".gateways/MyGateway.Gateway" -q "id" | tr -d '"')
# List data sources on gateway
fab api -A powerbi "gateways/$GATEWAY_ID/datasources"
# Get data source status
fab api -A powerbi "gateways/$GATEWAY_ID/datasources/$DATASOURCE_ID"
Update Data Source Credentials
# Update credentials (basic auth example)
fab api -A powerbi "gateways/$GATEWAY_ID/datasources/$DATASOURCE_ID" -X patch -i '{
"credentialDetails": {
"credentialType": "Basic",
"credentials": "{\"credentialData\":[{\"name\":\"username\",\"value\":\"user\"},{\"name\":\"password\",\"value\":\"pass\"}]}",
"encryptedConnection": "Encrypted",
"encryptionAlgorithm": "None",
"privacyLevel": "Organizational"
}
}'
7 - Take Over Ownership
When a semantic model owner leaves the organization:
WS_ID=$(fab get "ws.Workspace" -q "id" | tr -d '"')
MODEL_ID=$(fab get "ws.Workspace/Model.SemanticModel" -q "id" | tr -d '"')
# Take over semantic model ownership
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/Default.TakeOver" -X post
8 - Common Patterns
Dev to Production Deployment
#!/bin/bash
DEV_WS="Dev.Workspace"
PROD_WS="Prod.Workspace"
# 1. Export from dev
fab export "$DEV_WS/Sales.SemanticModel" -o ./deploy -f
fab export "$DEV_WS/SalesReport.Report" -o ./deploy -f
# 2. Import to prod
fab import "$PROD_WS/Sales.SemanticModel" -i ./deploy/Sales.SemanticModel -f
fab import "$PROD_WS/SalesReport.Report" -i ./deploy/SalesReport.Report -f
# 3. Trigger refresh
PROD_WS_ID=$(fab get "$PROD_WS" -q "id" | tr -d '"')
MODEL_ID=$(fab get "$PROD_WS/Sales.SemanticModel" -q "id" | tr -d '"')
fab api -A powerbi "groups/$PROD_WS_ID/datasets/$MODEL_ID/refreshes" -X post -i '{"type":"Full"}'
# 4. Verify
fab api -A powerbi "groups/$PROD_WS_ID/datasets/$MODEL_ID/refreshes?\$top=1" -q "value[0].status"
Backup Semantic Model
# Export definition for version control
fab export "Prod.Workspace/Model.SemanticModel" -o ./backups/$(date +%Y%m%d) -f
git add ./backups/
git commit -m "Backup Model $(date +%Y-%m-%d)"
Incremental Refresh Setup
For large models, use incremental refresh:
- Configure in Power BI Desktop with RangeStart/RangeEnd parameters
- Publish to workspace
- First refresh creates partitions:
# Monitor partition creation
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes?\$top=5"
9 - Safety Guidelines
- Always verify workspace context before refresh operations
- Test in dev first — never refresh production without testing
- Monitor refresh duration — set appropriate timeouts
- Backup before major changes — export definition before updates
- Use enhanced refresh for large models to avoid timeouts
