	<AimSection><Paragraph>If you want to change the number of resources on an operation, you can do this by changing the value of the <GUIRef href="/baanerp/ti/sfc/tisfc0110m000#tisfc010.mopr" role="formfield" Update="No">Man Occupation for Production</GUIRef> field, or the <GUIRef href="/baanerp/ti/sfc/tisfc0110m000#tisfc010.mcoc" role="formfield">Machine Occupation</GUIRef> field in the <GUIRef href="/baanerp/ti/rou/tirou1102m000" role="session">Routing Operations (tirou1102m000)</GUIRef> session, or the <GUIRef href="/baanerp/ti/sfc/tisfc0110m000" role="session">Production Planning (tisfc0110m000)</GUIRef> session. If you want to avoid that the changed man occupation or machine occupation results in changed production costs, you must click Yes if SSA ERP asks the question whether to recalculate the cycle time. If you do so, SSA ERP calculates the following:</Paragraph>
