This is working as designed. When an uplift happens for a standard or supplier rate on an element type, the Element Details table overwrites the old rate with the new one but keeps the original start date for that row, the date when the element was first purchased. The purchase order revision pulls its data from this table, which is why the new PDF shows the original start date with the updated rate.
There’s another table called Real Commitments, which payment and billing cycles use. This table creates a new line for the uplift but purchase order outputs don’t pull data from here.
You can see the rate differences by:
Opening previous purchase order revisions via their hyperlinks in the care package screens for that person.
Checking the Costs tab for that element, which shows a line-by-line split of rates and periods.
Running a B13 Commitment Report, which details how rates changed and over what periods.
A manual rate uplift doesn’t create a new purchase order revision output. It just appears as plain text on the summary screen instead of a clickable hyperlink.
