Hi
Which SRM version are you using ?
All the Data after makning changes in the PO document, will be also aviavale in BBP_DOC_CHANGE_BADI for the filter type- BUS2201 (Purchase orders) in your case. You can either do a validation there using BBP_DOC_CHECK_BADI.
The  Business Add-Ins [BADI] - BBP_DOC_CHECK_BADI should be used for customer messages to be triggered ->
