If you don't mind SCOOB, i answer the question here. If it's a problem, please remove my comment.
Maybe you know how to fix empty shop in Dubgeon Info? I cant find quests or files on server for put in key num ;(
- The python part has a burnt id for the dungeon shop. 1003.
'net.SendChatPacket("/open_shop {}".format(1003))'
it must be the same as in the db side shop id, default 1003 - all_bow - 0 what we have.
You only need to add to the shop item table the items what you want to sell. As i see well, you can use it with item_proto sell prize (only yang).
So for example: shop_vnum: <default: 1003> - item_vnum: <item what you want to sell> - count: <the number the item>.
