Am very new to celonis data connection and events including PQL
I have a data set for Requisition PR (EBAN), Procurement PO (EKKO and EKPO)
I also have the finance data invoices BSEG.BSCHL = ‘31’
Is there a column or a query l can use to directly link the invoices (BSEG) to POs(EKPO) without the table EKBE
Eventually, l have to compare PR, PO and Invoice value?
