## Content

**Intro:** The Master Production Schedule (MPS) in SyteLine sits between demand management and detailed MRP, providing a stabilized production plan for finished goods and major subassemblies. An effective MPS absorbs demand variability, respects capacity constraints, and gives the shop floor a realistic target. SyteLine's MPS functionality is configured through the Master Schedule form and interacts with planning parameters, time fences, and rough-cut capacity profiles.

**Sections:**

#### MPS Item Selection and Planning Bills

**Body:** Not every item needs to be master scheduled. MPS items should be limited to finished goods, critical subassemblies, and long-lead-time components that gate production capacity. SyteLine's Planning BOM feature allows master scheduling at a product family level and then disaggregating to specific item numbers based on mix percentages.

**Bullets:**

- MPS flag enabled on SL_Item for finished goods and critical subassemblies only
- Planning BOM configuration with percentage splits for product family disaggregation
- Planner Code assignment grouping MPS items by product family for focused schedule reviews
- MPS items excluded from standard MRP regeneration to prevent schedule instability
- Super BOM structures for configure-to-order items with option percentage planning

#### Time Fence Management for Schedule Stability

**Body:** SyteLine time fences create zones where schedule changes are progressively restricted. The Demand Time Fence, Planning Time Fence, and Frozen Zone protect the near-term schedule from demand fluctuations while allowing flexibility in the outer planning horizon. Without time fences, every new customer order causes MRP to reschedule existing production, creating shop floor chaos.

**Bullets:**

- Demand Time Fence (DTF): inside this fence, only actual orders drive MPS, forecast is ignored
- Planning Time Fence (PTF): inside this fence, MRP generates exception messages but does not auto-plan
- Frozen Zone: first 1-2 weeks where no schedule changes allowed without management approval
- Time fence values set per item class: 2-week DTF for MTS, 1-week DTF for MTO items
- Exception message review process for changes proposed inside the Planning Time Fence

#### Rough-Cut Capacity Planning for MPS Validation

**Body:** Every MPS must be validated against available capacity before it is released to MRP. SyteLine's rough-cut capacity planning (RCCP) compares the MPS load against resource capacity profiles to identify overloaded periods. RCCP operates at a higher level than CRP, using resource profiles rather than detailed routing operations, making it faster for what-if analysis.

**Bullets:**

- Resource profiles mapping each MPS item to hours required on critical work centers
- Capacity load report by work center showing MPS-generated demand vs available hours per period
- Overload resolution: shift overtime, alternate resources, MPS quantity adjustment, or due date revision
- Weekly MPS review meeting using RCCP reports to approve or adjust the master schedule
- RCCP what-if scenarios comparing capacity impact of alternative MPS proposals before commitment
