Run with CJ88 or CJ8G.<\/div><\/details><h3>\ud83d\udfe1 Intermediate<\/h3><details class=\"sap-qa\"><summary>What is the difference between cost planning and budgeting? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\"><b>Planning<\/b> is the estimate of what the project will cost (often several versions). The <b>budget<\/b> is the approved, binding amount. Budget is typically copied from the plan, then released in stages, and it is the basis for availability control.<\/div><\/details><details class=\"sap-qa\"><summary>Explain the methods of cost planning in PS. <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\">Overall planning on WBS (CJ40), cost element planning (CJR2), unit costing \/ Easy Cost Planning (CJ9ECP with costing models), and network costing (automatic from activities: labour, materials, services). Many companies combine Easy Cost Planning for early estimates and network costing for execution.<\/div><\/details><details class=\"sap-qa\"><summary>How does a capex project settle to an asset? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\">During the project, a settlement rule to an <b>asset under construction (AuC)<\/b> is created automatically through the investment profile. At completion, the AuC is settled to final assets using line item settlement in Asset Accounting, and the project is technically completed.<\/div><\/details><details class=\"sap-qa\"><summary>What is results analysis? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\">For customer projects, results analysis (KKA2\/KKAJ) calculates work in process, reserves for unrealised costs and revenue to recognise, using methods such as percentage of completion (POC) based on cost or revenue. The results are settled to FI and CO-PA. In S\/4HANA, event-based revenue recognition is the modern alternative.<\/div><\/details><details class=\"sap-qa\"><summary>What is earned value analysis in PS? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\">Progress analysis compares <b>BCWS<\/b> (planned value), <b>BCWP<\/b> (earned value) and <b>ACWP<\/b> (actual cost) to derive schedule and cost variances. Percentage complete comes from measurement methods such as milestone, time-proportional, estimate or quantity-proportional.<\/div><\/details><details class=\"sap-qa\"><summary>What is project stock and when is it used? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Intermediate<\/small><\/summary><div class=\"sap-a\">Special stock Q, which is valuated or non-valuated stock reserved for a specific WBS element.

How do you design it? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Scenario<\/small><\/summary><div class=\"sap-a\">Create a sales order with a billing plan (milestone type) and link it to a <b>billing WBS element<\/b>. Assign milestones to network activities or WBS elements with the &#8220;sales document date&#8221; usage. When a milestone is confirmed, the billing block on the related billing plan date is removed and SD billing (VF01\/VF04) creates the invoice. Revenue then flows into the WBS for results analysis or EBRR.<\/div><\/details><details class=\"sap-qa\"><summary>Users are posting costs beyond the approved budget. How do you control this? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Scenario<\/small><\/summary><div class=\"sap-a\">Activate availability control in the budget profile with tolerance limits by activity group: for example a warning at 90%, an email at 100% and an error at 105%. Choose the usage basis (released budget), and run reconstruction of availability control (CJBN) after changes. Make sure commitments from POs are included.<\/div><\/details><details class=\"sap-qa\"><summary>Settlement fails for many WBS elements at month end. What do you check? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Scenario<\/small><\/summary><div class=\"sap-a\">Missing or incorrect settlement rules, the settlement profile and allocation structure (cost elements not covered), project status (for example CLSD or a user status blocking settlement), locked periods, and receiver validity such as a closed cost centre or an asset that is not yet created.

Create one project per site or major investment with a standard WBS template: level 1 the project, level 2 phases or cost categories, level 3 work packages as account assignment elements. Use an investment profile for AuC, a common budget profile with AVC, and standard reports by programme position.<\/div><\/details><details class=\"sap-qa\"><summary>How do you handle timesheets for project staff? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Scenario<\/small><\/summary><div class=\"sap-a\">Use CATS (CAT2) with the network activity or WBS as the receiver. Approval through workflow, then transfer to PS (CAT5) to create confirmations or direct activity allocations. Labour cost is valued with the activity type rate of the sender cost centre.<\/div><\/details><details class=\"sap-qa\"><summary>What changes when you move a PS customer to S\/4HANA? <small style=\"margin-left:auto;font-size:11px;color:#6366f1;white-space:nowrap\">Scenario<\/small><\/summary><div class=\"sap-a\">Assess the Simplification List: confirm the revenue recognition approach (results analysis vs EBRR), check deprecated functions, adopt Fiori monitoring apps, check Business Partner conversion for customer and vendor, run custom code checks for PS enhancements, and validate the settlement and asset accounting changes.
