Consumption, wastage and reversals
Record actual material use and understand when it changes stock and costs.
Use a consumption log for actual usage
Inventory Consumption separates preparing a log from posting its stock effects. The page has Logs, Analytics, Transactions and Wastage tabs. Select the project before reviewing the figures. A manual form records material, consumed quantity, wasted quantity, unit and reason; it does not expose every return or issue-link operation supported elsewhere by the system.
- 01
Prepare a log
Create a log with project and date, add material lines, enter consumed and wasted quantities and explain wastage. Check the source first if a DPR or material issue already covers the same work.
- 02
Review if required
Save a draft or submit for approval using the available option. Pending approval must be reviewed before posting; rejected work needs correction. A permitted draft can also be posted directly.
- 03
Post and verify
Post the eligible log, then inspect its status, Transactions and project stock. A saved or approved log is not yet a posted movement.
Avoid counting one use twice
An issue already records stock leaving the store. Linked consumption records what happened to that issued material; a separate manual stock-consumption entry can represent a different movement. Do not use a fresh manual log to repeat issued quantities without understanding its source. When auto-post DPR consumption is enabled, inspect the generated log before entering usage again. Supported returns restore stock through the linked workflow; the current manual entry form sets return quantity to zero.
Approval applies when required. Only posted entries affect consumption reporting; reversal has its own checks.
Reverse a posted mistake with a reason
Use Reverse on a posted log when the entry is wrong and you have permission. Enter a meaningful reason and review the resulting reversal transactions and balances. A reversal preserves the trail; it is not an edit to erase the original event. Downstream stock or issue activity can make a reversal invalid, so follow the error message rather than forcing a negative balance.
Use wastage controls and analytics
Company settings include wastage percentage, high-wastage quantity threshold and whether wastage approval is required. They help flag entries needing review; they do not prove that every variance is waste. Analytics uses posted usage, while estimates may compare stage-linked issue costs. Compare the same project, period, material and source before explaining a difference. See Estimation.
