Need your kind assistance regarding the below PO discount scenario:

Total Budget on Category 01: 100,000
PO Amount Before Discount: 200,000
PO Amount After Discount: 100,000

Could you please advise how this scenario should be handled from the budget and PO processing perspective?

In Dynamics 365 Finance & Operations (Project Management and Accounting + Procurement), budget control and encumbrance are driven by the PO line amounts as they are financially posted (i.e., after trade/line discounts are applied)—not the pre-discount value.
✅ How your scenario behaves in standard D365 F&O
Given:

Project budget (Category 01): 100,000
PO amount before discount: 200,000
PO amount after discount: 100,000

🔹 System behavior

Budget consumption is based on PO line net amount
- The system considers 200,000 → 100,000 (after discount) for commitment.
- So only 100,000 is reserved/encumbered against the project budget.
No separate budget consumption for discounts
- Trade discounts reduce the PO line amount.
- Discounts are not treated as separate budget-relevant costs.
Result
- Budget = 100,000
- Committed via PO = 100,000
- Available budget = 0 (fully utilized)

🔹 Key configuration points to verify
To ensure this works as expected, check:
1. Budget control configuration
Path:
Budgeting > Setup > Budget control configuration

Ensure “Control budget on commitment” is enabled (if required)
Verify project is included in budget control rules

2. Procurement integration with project
Path:
Project management and accounting > Setup > Posting > Cost categories / Integration

Confirm PO lines are posted to the correct Project category (Category 01)

3. Purchase order line discount setup

Trade discounts should be applied at:
- Purchase order line
- Or vendor pricing agreement
Ensure discounts are not configured as separate charge lines, unless intended

🔹 Important business consideration
If your organization expects:
Budget should be checked against gross PO value (before discount)
Then standard behavior will NOT meet that requirement.
In that case, you would need a customization or workaround such as:

Budget reservation based on gross amount (before discount) via extension
Or enforcing pricing rules that prevent discount-driven budget reduction
Or using pre-encumbrance logic adjustment in budget control

🔹 Summary

Item	Amount
Budget	100,000
PO Gross	200,000
Discount	100,000
Budget consumption (standard)	100,000
Status	Fully utilized

If you want, I can also explain how this behaves with commitment accounting, vendor invoice variance, or project category cost posting, since those often cause confusion in similar scenarios.
