fetching PO changes relevant for given version

Hi Gurus,

We activated Version management for Purchase orders & all relevant settings are done to capture the changes & display them on PO print.

But the problem is, when we print the PO, changes done with all versions are being displayed every time.i.e.

lets say there is PO no: XXXX. & initial version no:0

then we did some changes to PO & now version no:1

then further modified the PO & now version no:2.

When we print the PO displaying changes, system is showing all changes done from version no:0 to 2. Actually system should show only changes between version no 1 & 2.

we are using SAP FM:ME_READ_CHANGES_EINKBELEG

please suggest a logic to fetch changes between latest version to last version.

Thanks in advance
