Before importing the opening balance, for serial number item, ITEM SERIAL column is compulsory. All the serialized number need to be key in and separated by comma.
For Example:
Item : Item A
Quantity :5
Under ITEM SERIAL column,you need to key in as 20003,20004,20005,20006,20007
What if we have a lot of serial number for one item?
You don't have to key in one by one.
Open it in Excel file then just follow these few steps to before copy it and paste to ITEM SERIAL column
When the file is ready, continue to import opening stock. You can refer to http://intranet.wavelet.asia/projects/wavelet-ms/wiki/Importing_Opening_Stock
