ICMR - Manage Assignments column "Up to Now (YTD)" not working

Hello all,

I'm presently investigating the Manage Assignments app. The lawsuit lone wants to analyse the cumulative values during the year betwixt the starring portion and the trading partner. Therefore, we made lone the "Up to Now (YTD)" file available, which, according to SAP, "Shows the aggregated amounts of the trading portion pairs up to the clip of the execution of the report. This incorporates immoderate caller postings detected since the past matching run."

Shouldn't the values, connected that circumstantial column, connected the play of December, aggregate the worth from January to December? 
In my case, erstwhile I filter the values to 012.2024 period/fiscal year, the Leading Unit values look to beryllium lone from November and December.

Thanks successful advance.
