    Lookup tables is used in Enterprise Custom Fields. We can create Lookup tables programmatically either from CSOM or PSI. Here below is the example of creating Lookup tables using CSOM.

    Microsoft.ProjectServer.Client.LookupTableCreationInformation lookupTableInfo = new Microsoft.ProjectServer.Client.LookupTableCreationInformation();
    try
    {
    	lookupTableInfo.Id = new Guid();
    	lookupTableInfo.Name = "Applications";
    	lookupTableInfo.SortOrder = Microsoft.ProjectServer.Client.LookupTableSortOrder.UserDefined;
    
    	#region Creating Lookup Mask
    	List<Microsoft.ProjectServer.Client.LookupMask> lstMask = new List<Microsoft.ProjectServer.Client.LookupMask>();
    
    	Microsoft.ProjectServer.Client.LookupMask maskInfo = new Microsoft.ProjectServer.Client.LookupMask();
    	maskInfo.Length =0;
    	maskInfo.Separator = ".";
    	maskInfo.MaskType = Microsoft.ProjectServer.Client.LookupTableMaskSequence.CHARACTERS;
    	lstMask.Add(maskInfo);// you can create more than one mask 
    
    	lookupTableInfo.Masks = lstMask;
    	#endregion
    
    	char separator = lstMask[0].Separator.ToCharArray()[0];
    		
    	#region Creating LookupTable Entry
    
    	Dictionary<string, Guid> AvailableLookupEntry = new Dictionary<string, Guid>();
    	List<Microsoft.ProjectServer.Client.LookupEntryCreationInformation> lstEntry = new List<Microsoft.ProjectServer.Client.LookupEntryCreationInformation>();
    
    	string[] multiLevel = "Your Full Value".Split(separator);
    	int length = multiLevel.Length;
    	
    	AvailableLookupEntry.Add( "Your Full Value", new Guid());
    
    	string fullValue = multiLevel[length - 1];
    
    	StringBuilder sb = new StringBuilder();
    	if (length > 1)
    	{
    		for (int i = 0; i < (length - 1); i++)
    		{
    			sb.AppendFormat("{0}{1}", multiLevel[i], separator);
    		}
    		sb.Length--;
    	}
    
    	Microsoft.ProjectServer.Client.LookupEntryCreationInformation lookupEntryInfo = new Microsoft.ProjectServer.Client.LookupEntryCreationInformation();
    	lookupEntryInfo.Id = new Guid();
    	lookupEntryInfo.Description = "Lookup Entry Description";
    	lookupEntryInfo.SortIndex = Convert.ToDecimal("1.0000000000");
    
    	if (AvailableLookupEntry.ContainsKey(sb.ToString()))
    		lookupEntryInfo.ParentId = AvailableLookupEntry[sb.ToString()];
    
    	lookupEntryInfo.Value = new Microsoft.ProjectServer.Client.LookupEntryValue();
    	lookupEntryInfo.Value.TextValue = fullValue;
    
    	lstEntry.Add(lookupEntryInfo);
    
    	lookupTableInfo.Entries = lstEntry;
    	#endregion
    
    	Microsoft.ProjectServer.Client.LookupTable newLookupTable = projectContext.LookupTables.Add(lookupTableInfo);
    	projectContext.LookupTables.Update();
    	projectContext.ExecuteQuery();
    }
    
    catch (Exception ex)
    {
    	//log exception
    }

    Hope this code will help you. Thanks
