I have 2 tables Warehouse (WH) and Sales (SL)
WH has fields: Prod_Code, Expiry_Date & Quantity
SL has fields: Prod_Code, Quantity.
I am trying to achieve the following: For every sale that I make, I want the quantity sold to be subtracted from the WH from the same Prod_Code which will expire sooner. This way, I follow FIFO.
Can someone PLEASE help me with this??
I am a roockie and I am trying to make this work!
Thank you in advnace
