Reg : PO text updation based on Work Order no and Operation

Hi Team,

I have a requirement that  PO item Texts needs to be updated with some Texts based on the the Work order and Operation no from the Account assignment.

As soon as the Work order and Operation is given , texts needs to be updated for the item.

The problem is i am not getting the Work order no and Operation no .

I have tried the BADI ME_PROCESS_PO_CUST , here those work order no and operation no details are not available.

So my question is that is there any BADI/EXIT where i will get all the PO and Work order Details of the corresponding PO Item in order to update the PO texts.

Please let me know.

So do i need to go for an implicit enhancement??

Please do suggest me.

Thanks!
