The Synthesized Platform provides SAP module knowledge and configurable relationship mapping, respecting the boundaries and table relationships within each SAP functional area.

## Overview

SAP organizes functionality into modules, each with its own set of master data and transactional tables. The platform understands these module boundaries and:

- Selects relevant tables for the chosen module
- Maps relationships between tables using pre-configured and custom virtual foreign keys
- Applies module-appropriate data transformations
- Maintains referential integrity across related tables

## Material Management (MM)

The MM module covers procurement, inventory management, and material master data. MM includes a guided workflow wizard for streamlined configuration.

## Module Selection Best Practices

### Start with One Module

Begin with a single module to:

- Validate connectivity and permissions
- Test transformation rules
- Establish baseline performance metrics

### Consider Dependencies

Some modules share data:

- **MM + FI**: Purchase orders create FI documents
- **MM + CO**: Goods movements create CO postings
- **FI + CO**: Financial postings update controlling

When working with dependent modules, ensure consistency in masking rules across shared fields.

### Validate Module Coverage

Before running workflows:

1. Verify all required tables exist in source schema
2. Confirm user has SELECT permissions on all tables
3. Check that target schema can accommodate the data

## Custom Module Configuration

All SAP modules can be configured via YAML workflow definitions. The MM module offers a guided workflow wizard for streamlined setup, while other modules use the standard workflow editor:

```yaml
tables:
  - table_name_with_schema: "SCHEMA.CUSTOM_TABLE"
    transformations:
      - columns: ["MANDT"]
        params:
          type: passthrough
      - columns: ["CUSTOM_FIELD"]
        params:
          type: unique_hashing
```

Contact support for guidance on custom SAP module configurations.
