Thailand supermarkets stock control

[superal]

I have lost count of how many times that a food item is sold out in Thai supermarkets . Anyone know how stock levels are maintained ? Rightly or wrong , I thought that an items bar code , when swiped at the checkout not only was for the ease of compiling the bill but was also sent to the data page , where if the item gets near to low stock , it is automatically reordered . That doesn't seem to be the case in Thailand , or is it ? Only recently I ordered online several packs of a frozen vegetable which I would pick up at the store . When I went to collect , there was nothing to pick up , just a " No have " from a supervisor . Although the supermarkets are generally well presented , their stock control needs attention . Does anyone have retail experience in Thailand ?
