Helper IIINeed help with Month over month calculation
I have input dataset like this :
| Item | Sub Item | Month | Cost |
| Item 1 | Subitem 1 | 30-Jun-23 | 200 |
| Item 1 | Subitem 2 | 30-Jun-23 | 300 |
| Item 1 | Subitem 1 | 31-May-23 | 400 |
| Item 1 | Subitem 2 | 31-May-23 | 600 |
| Item 2 | Subitem 1 | 31-May-23 | 500 |
I want to caculate Month over month cost saving i.e June month cost - May month cost for the various items and subitems .
Require a matrix outout like this -
| Item | Sub Item | 30-Jun-23 | 31-May-23 | Cost Saving |
| Item 1 | Subitem 1 | 200 | 400 | -200 |
| Item 1 | Subitem 2 | 300 | 600 | -300 |
| Item 2 | Subitem 1 | - | 500 | -500 |
| Total row | 500 | 1500 | -1000 |

The challenge I am facing is this .. If you see the Item 2 in the input data , It does NOT have any record (i.e cost) for June month . There is May cost which is 500 . In this case I want June cost to be considered zero and cost saving calculated as (0-500) = -500 and the above matrix to be created with proper totals
In other words it is as good as inserting below row in input data
| Item 2 | Subitem 1 | 30-Jun-23 | 0 |
