What is the data type of your memory tag? What is the data type of your database field? (Is it the same? Is it big enough to accept the data?) If you go to the gateway _Status | Diagnostics | Logs_ do you see any errors? ---

If you want to write your memory tag into the table, why are you “targeting” it as read-only instead of its own column, i.e. target name: “lot\_wagon\_xxxxx” ? ---

Its not the problem, the tags never got update in the transaction group, he always got the “null” value But, in the browser tags the value its update ---

The problem is not the read-only and is not the SQL table. this tag “lot\_wagon\_for\_tab\_palettes” in the transtion group read “Null” ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/9/59b5196829362a96aace08971104567a59c97439.png) But in the browser Tags , this same tag have a real value : [![](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/9/59fb8ec079e1bb42d158c945f6ec5e32f37f9a4b.png) ](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/9/59fb8ec079e1bb42d158c945f6ec5e32f37f9a4b.png) And i need the value on the transaction group. ---
