Hi,
We always take a dump of EKKO and then manually load the set up table with the POs as per EKKO.
For a series of PO numbers ,say based on PO document type or document date or posting date ,We will match the total amount in BW with that of the EKKO table.
We had no issues and the data was matching.
In case any PO range is missing, we can anaylse the same and check with Functional Consultants as to what is the significance of those POs.They would give the reasons.
