ME2J vs CJI5 report difference

Hi Experts,

We have scenario where is CJI5 showing the amount against one PO, whereas if I check ME2J report its missing value against that PO.

I am running this report against one project only with same parameter.

I have check EKKO, EKPO for that PO number but there is no data for it, whereas if check in WBS budget tables I can see value against that WBS.

So what could be the scenario to occur this type of difference in reports
