Contractors reviewing material purchases need clear evidence for item prices, project context and finance posting. BlueberryERP documentation supports two distinct review areas: Item Price History for item and LPO price records, and Receipt Voucher validation for currency and currency-rate fields. The supplied product evidence does not document currency or exchange-rate fields on purchase orders or LPOs.
Separate purchasing reference from finance validation
Item Price History lets users select an item and review recorded price history. Filters include date range, project, store, activity and sub-activity. The documented Latest Order Price is based on the most recent unit price from an LPO, determined by the latest document date. This makes the screen a purchasing reference for comparing item prices and context; it is not evidence of a purchase-order exchange-rate control.
Separately, the documented Receipt Voucher rules require a valid currency and a currency rate greater than zero. That validation applies to Receipt Voucher entry. It should not be presented as validation of a purchase order or LPO exchange rate.
A documented review workflow
- Identify the item, project, store and purchasing context under review.
- Use Item Price History to select the relevant item and apply appropriate date, project, store, activity or sub-activity filters.
- Review the available item and LPO price records, remembering that the documented Latest Order Price is based on the most recent LPO document date.
- When reviewing a Receipt Voucher, confirm that the selected currency is valid and that the currency rate is greater than zero, as required by the documented Receipt Voucher validation rules.
- Record differences or missing context for human review before the responsible team proceeds.
| Review stage | Documented evidence | Control boundary |
|---|---|---|
| Item reference | Item Price History supports item selection and price-history review. | Confirm the correct item and relevant context. |
| History comparison | Filters include date range, project, store, activity and sub-activity. | Compare relevant records rather than assuming the latest price is applicable. |
| LPO reference | Latest Order Price is based on the most recent LPO document date. | Use the record as purchasing context, not as proof of exchange-rate validation. |
| Receipt Voucher validation | Receipt Voucher rules require a valid currency and a currency rate greater than zero. | Apply this documented rule to Receipt Voucher entry only. |
| Human review | Unusual or incomplete information can be investigated by the responsible team. | Do not infer an undocumented automated approval or control. |
Questions for a contractor checklist
- Does the selected item match the project requirement?
- Were the date, project, store and activity filters selected deliberately?
- Is the LPO price record relevant to the purchasing review?
- For a Receipt Voucher, is the currency valid and is the currency rate greater than zero?
- Has a responsible person reviewed unusual differences or missing information?
These checks help construction, MEP and specialist contractors organize purchasing evidence and finance validation. They do not establish a native BlueberryERP purchase-order exchange-rate feature, predict currency movements, or provide accounting or tax advice.
