Refresh button

[Anonymous]

Hi all,
Im using the sql postrgres and getting the "OLE DB or ODBC: [DataSource.Error] PostgreSQL: 40001: canceling statement due to conflict with recovery" error when trying to refresh my model.
Searched for a solution, but still could not solve it, despite having understood the error.
Anyway, figured out that if I refresh one field at time dont get the error. That made me think if its possible to create different buttons to refresh different selections of fields.
I know that I can select the field in the power query editor to be refreshed or not, but as I told I intend to create more than one group.
Does anyone can help me?
