# Multi Stage BOM

<p class="doc-lead">A Multi Stage BOM defines stage-wise production for an item — each stage has processes with their own intermediate items, BOMs, employees, and percentage allocation. Used for complex manufacturing with multiple process steps.</p>

<li>Configure <a href="#/production/production-stage-group">Production Stage Groups</a> and <a href="#/production/production-stage">Production Stages</a> first.</li>
<li>Click <b>New</b> on Multi Stage BOM.</li>
<li>Enter <b>Name</b>, <b>Item</b>, <b>Quantity</b>, <b>Unit</b>.</li>
<li>Add <b>Stages</b> with <b>Processes</b> — each process specifies item produced, BOM, employee, process after, and % alloted.</li>

<p><b>How does this differ from Bill Of Materials?</b><br>A standard BOM is single-step. Multi Stage BOM chains multiple stages and processes, each with its own BOM and issue/voucher/receipt cycle.</p>

<p><b>Where is process progress reported?</b><br><a href="#/production/reports/process-summary">Process Summary</a> and Production Status Report stage columns.</p>
<p><b>Stages required?</b><br>Define <a href="#/production/production-stage">Production Stage</a> and stage group before multi-stage BOM.</p>
<p><b>Raw materials per stage?</b><br>Each stage process lists inputs and outputs for that step.</p>
<p><b>Can I export this report?</b><br>Yes — use Export from report actions for Excel analysis.</p>
<p><b>Which production setting affects this?</b><br>Review <a href="#/production/production-settings-config">Production Settings</a> for variance, quantity, and BOM rules.</p>
