Answer:

Now you can select Product Child according to Warehouse. This feature is available in Sale, Sale Return,  Purchase Return, Stock Transfer, Stock journal Entry etc. To implement this feature please use the following steps…..

1. Go to Main Menu > Sales Management > Transaction > Sales Invoice (POS)(STS) 
2. Alt + O (open option screen)
3. Set “Allow Negative Stock = No”.
4. Save
5. Escape
6. Again open Sale screen (scan POS)
7. Alt + L (select product from the list)
8. After pressing enter it will open product child list (if available) with warehouse details (if available).

NOTE:

• This Feature is available only if “Allow Negative Stock = No”.
• If “Allow Negative Stock = No” FusionRetail 6 will restrict from changing the Warehouse from the Transaction screen

• If “Allow Negative Stock = Yes” warehouse list will not be available in product child list. In this situation you can change warehouse directly from the transaction screen.
