The company is the main electronic products , electronic products tend to SN. 's Management has certain rules, so now the company is envisaged in the warehouse receipt , when only do the number of records , but in the time of sale , in addition to the number of records , but also record the product SN., for this management approach , I just thought that the use of " inventory list" to add products SN., may I ask , there are other more convenient way?

For example: A warehouse 10
So inventory ticket :
Warehouse    number    SN.
A warehouse   9
2 warehouse   1        1234
SN through such means converting sales of the product. , Because the sales of the product will be attributed to another warehouse , easy to manage.
