Power Bi Input Methods in Microsoft Fabric: Use Cases and Technical Solutions

Power Bi Input Methods in Microsoft Fabric: Use Cases and Technical Solutions

Introduction

Organizations using Power Bi within Microsoft Fabric often need to capture data directly from users, not just consume existing data sources. The fundamental need is the same across scenarios: enabling users to input, edit, and interact with data that feeds into Power Bi reports and analytics.

Prior to Microsoft Fabric, organizations had two native Power Platform options for data input:

• Power Bi Custom Visual
• Power app

Since May 2025, Microsoft has Enabled Translytical flows. This tutorial examines the three technical solutions—Fabric Translytical Flows, Power Bi Custom Visuals, and Power Apps—and help you to navigate the different options.

Part 1: Common Use Cases for Power Bi Input

In our consultancy experience, we have seen many different use cases for Power Bi input, but following two are most prevalent: financial budgeting and forecasting and master data mapping.

1. Financial Planning & Budgeting and sales forecasting

Business Need

Finance teams need to input budget figures, forecasts, and planning data directly within their analytical environment, rather than maintaining separate spreadsheets or systems.

A variation of the financial planning is the sales forecasting. Sales planners want to forecast the effectiveness of a campaign. A forecasting system exists, however sales planners have additional knowledge where the system is not aware of and want to be able to overrule the estimate.

Specific Requirements (all might not apply, depends on case complexity and context)

• Budget entry grids: Input annual budgets by department, product, or region
• Scenario planning: Create and compare multiple budget versions (optimistic, realistic, pessimistic)
• Variance explanations: Add comments explaining why actuals differ from budget
• Approval workflows: Track budget approval status and capture sign-offs
• Real-time actuals: Integrate live data from ERP systems for immediate variance analysis

Example Scenarios

• Monthly budget revisions with copy-paste functionality between periods
• Sales forecast revision
• Rolling forecasts that combine historical actuals with forward-looking estimates
• Capital expenditure planning with multi-level approval processes
• Cash flow forecasting integrating bank feeds and payment schedules

2. Master Data Management

Business Need

Maintain reference data that drives analytics, such as product catalogs, customer information, organizational structures, and chart of accounts.

Specific Requirements

• Attribute editing: Update product descriptions, pricing, and categories
• Hierarchy management: Maintain organizational structures and reporting relationships
• Data quality: Ensure consistency and accuracy of reference data
• Change tracking: Audit who changed what and when
• Bulk operations: Support mass updates and corrections

Example Scenarios

• Product master maintenance for retail analytics
• Customer segmentation updates for marketing campaigns
• Employee organizational chart management for HR reporting
• Chart of accounts mapping for financial consolidation

Part 2: Technical Solutions Analysis

Now that we’ve established the business needs, let’s examine how each technical solution addresses these use cases and their respective limitations. We will review fabric translytical flows, Power Bi Custom Visual and Power Apps.

1. Fabric Translytical Flows

Solution Overview

Fabric Translytical Flows combine transactional and analytical processing, enabling real-time data streaming and processing within the unified Fabric architecture.

Microsoft provides an excellent tutorial. Tutorial – Create translytical task flow – Power Bi | Microsoft Learn

Architecture is as followed:

Creation Steps:

1. Create user data function
2. Setup database and create destination table
3. Link table to model
4. Select slicer visual, only text slices are available.

Solution evaluation

Advantages

• Fully fabric native setup
• Not overly complex, yet enables customization required

Disadvantages

• Quite a few limitations (see below), which makes it only practical usable for simple use cases

Overview of limitations

2.Power Bi Custom Visuals

Solution Overview

Custom visuals extend Power Bi’s native capabilities by providing interactive controls that enable direct data entry, editing, and user input within reports.

Power Bi Custom Visual has the advantage over translytical flow that it takes away limitations, e.g. all possible visualizations are possible, such as complex grid editing, etc.

Creation Steps:

1. develop custom visual
2. develop integration layer (function)
3. develop database

In our experience putting this together in one repository will help co-pilot with the context of the whole solution.

Solution evaluation

Advantage:

• full compliance possible with customer request, in essence no limitation (however very large datasets have additional complexity, as typical it runs in direct query mode)
• native Power Bi integration

Disadvantage:

• Extended development (development of the function, development of the visual, development of the database)
• large direct query calls can make it slow

3. Power Apps Integration

Solution Overview

Power Apps provides rich, form-based applications that can be embedded within Power Bi reports, offering comprehensive data entry experiences with advanced business logic and mobile optimization.

Creation Steps:

1. Create power app
2. Use the power app visual in Power Bi to add it to Power Bi.
3. Create integration layer (azure function, or use power automate or straight database connection)

Solution Evaluation

Advantages

• Full customization of application possible
• possible use outside of fabric and integration with outside fabric components

Disavantages

• power app is a non-Power Bi component, so end-user experience might feel as a less integrated solution
• power app is less easily to be added to your repository and copilot support is a bit less straightforward
• depending on setup, license cost might increase (as direct sql connection is a premium connector)

Summary

In summary here is an overview per feature

Solution Fit Matrix

Choosing the right Power Bi input method depends on your specific requirements, technical constraints, and user needs. The decision matrix above provides a framework for evaluation, but every implementation has unique considerations.

Our recommendation: Start with Translytical Flows for simple scenarios, upgrade to Custom Visuals when you need rich editing within Power BI, and choose Power Apps for complex business processes or mobile-first requirements.

Keep in mind that Microsoft has only released the translytical flow since May 2025 and the feature will have more possibilities in the future.
