    Enterprise Custom Fields includes custom formula and lookup tables. We can create CustomField programmatically either from CSOM or PSI. Here below is the example of creating CustomField using CSOM.

    Microsoft.ProjectServer.Client.CustomFieldCreationInformation customFieldInfo = null;
    try
    { 
    	projectContext.Load(projectContext.LookupTables,
    			lts => lts.Include(
    								lt => lt.AppAlternateId,
    								lt => lt.Id,
    								lt => lt.Name,
    								lt => lt.FieldType,
    								lt => lt.SortOrder,
    								lt => lt.Masks,
    								lt => lt.Entries
    							));
    		projectContext.ExecuteQuery();
    		
    	  Dictionary<Guid, Microsoft.ProjectServer.Client.LookupTable> availableLookupTables = new Dictionary<Guid, Microsoft.ProjectServer.Client.LookupTable>();
    		foreach (Microsoft.ProjectServer.Client.LookupTable lt in projectContext.LookupTables)
    		{
    			availableLookupTables.Add(lt.Id, lt);
    		}
    
    	#region CustomField Creation
    
    	customFieldInfo = new Microsoft.ProjectServer.Client.CustomFieldCreationInformation();
    	customFieldInfo.Description = "Test Description";
    	customFieldInfo.EntityType = projectContext.EntityTypes.AssignmentEntity;
    	customFieldInfo.FieldType = Microsoft.ProjectServer.Client.CustomFieldType.DATE;
    	customFieldInfo.Formula = "Your custom field formula";
    	customFieldInfo.Id = new Guid();
    	customFieldInfo.IsEditableInVisibility = false;
    	customFieldInfo.IsMultilineText = false;
    	customFieldInfo.IsRequired =false;
    	customFieldInfo.IsWorkflowControlled =false;
    	customFieldInfo.LookupAllowMultiSelect = false;
    
    	customFieldInfo.LookupDefaultValue = new Guid();
    
    	Guid lookupTableId = new Guid("// Available look up Id");
    	if (availableLookupTables.ContainsKey(lookupTableId))
    		customFieldInfo.LookupTable = availableLookupTables[lookupTableId];
    
    	customFieldInfo.Name ="Custom field Name";
    	Microsoft.ProjectServer.Client.CustomField newCustomField = projectContext.CustomFields.Add(customFieldInfo);
    	newCustomField.RollsDownToAssignments = false;
    	newCustomField.RollupType = Microsoft.ProjectServer.Client.CustomFieldRollupType.Formula;
    
    	projectContext.CustomFields.Update();
    	projectContext.ExecuteQuery();
    	#endregion
      
    }
    
    catch (Exception ex)
    {
    	//log exception
    }

    Hope this code will help you.Thanks
