These are result codes that communicate success (200) or failure (400) specific to the `Manage Data` operation.

Learn more about the [`Manage Data` operation](../../../../../../../learn/fundamentals/transactions/list-of-operations#manage-data).

**OpSuccess** `MANAGE_DATA_SUCCESS`

Manage data operation has executed successfully.

**op\_not\_supported\_yet** `MANAGE_DATA_NOT_SUPPORTED_YET`

The network hasn’t moved to this protocol change yet. This failure means the network doesn’t support this feature yet.

**op\_data\_name\_not\_found** `MANAGE_DATA_NAME_NOT_FOUND`

Trying to remove a Data Entry that isn’t there. This will happen if Name is set (and Value isn’t) but the Account doesn’t have a DataEntry with that Name.

**op\_low\_reserve** `MANAGE_DATA_LOW_RESERVE`

This account does not have enough XLM to satisfy the minimum XLM reserve increase caused by adding a subentry and still satisfy its XLM selling liabilities. For every new DataEntry added to an account, the minimum reserve of XLM that account must hold increases.

**op\_data\_invalid\_name** `MANAGE_DATA_INVALID_NAME`

Name not a valid string.
