Work in progress (WIA) English Work in Progress (WIP) – in SAP Business One refers to the value of production orders that have been started but not yet completed. WIA is a key component of production cost accounting.
Meaning of WIA accounts
SAP Business One uses special WIA accounts to correctly account for the value of goods in production:
- WIA Bank Account Captures the current value of unfinished goods
- WIA Variance Account Book differences between planned and actual production costs
- Material sample Upon removal of components, the value from the stores account is transferred to the WIA account Rebooked
Process in SAP Business One
Upon starting a production order, withdrawn materials and consumed resources are accumulated in the WIA account. At the time of production confirmation, the WIA value is settled and the finished item is booked to inventory. Differences between planned and actual expenditure are posted to the WIA variance account.
Practical tip
Regularly check WIA stock via the stock valuation report – high WIA stock can indicate unfinished or forgotten production orders.
