Create a table from existing table with count of items

[ConnieMaldonado]

Hello - I have a table with Work Order IDs and Items for each work order.  I need to create a new table that summarizes the count of items by work order ID.

OriginalTable:

I need a table with the following:

I used the following to create the table, but I'm not sure how to indicate that the 2nd column should be a count of items for each WorkOrderID:

New Table =

SUMMARIZE(OriginalTable,OriginalTable[Work_Order_Id])

Any help would be appreciated!  Thanks.

Hi @ConnieMaldonado 
Please try

New Table =
SUMMARIZE (
    OriginalTable,
    OriginalTable[Work_Order_Id],
    "ItemCount", COUNTA ( OriginalTable[Item] )
)
