You can update the new Liquidity field manually for each of your Investment Managers. If that's not practical for you, Fundriver Support is happy to help!
Use our Manager Data Load Template.
Enter the Manager GLID in column A and the Liquidity in column N.
Text is required in column B and D as well- however these fields will not be updated when Fundriver Support uploads your data. We suggested just copying the data from column A (MGLID) over to those two columns.
