# Manage Data These are result codes that communicate success (200) or failure (400) specific to the `Manage Data` operation. Learn more about the [`Manage Data` operation](/start/list-of-operations.md#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 XBN to satisfy the minimum XBN reserve increase caused by adding a subentry and still satisfy its XBN selling liabilities. For every new DataEntry added to an account, the minimum reserve of XBN that account must hold increases. * op\_data\_invalid\_name `MANAGE_DATA_INVALID_NAME` Name not a valid string. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
