Any Standard Message for RFQ not to change

Question

Dear Gurus,
My scenarios is, once RFQ is maintained and PO is issued to Vendor, then RFQ should not allow to change? if RFQ want to change then PO has to be deleted and then RFQ can be allow to change.
Is there any standard message to restrict RFQ to be amended - even after issuing a PO against an RFQ
Regards
RS

Hi,
Go to the T-code SE24.
Enter CL_EXITHANDLER. Then display . Then select the Get_instance method
Put the break Point in the in the Beginning where tht showing the Exit_name and class_name as the output.
That will be in the line 20-30. Then run the T-code ME47 and any code.
In the Exit _name u can see the BADI name.
Just Take all the BADI Names and go to the Documentation of all the BADI's. Then select a BADI tht suits ur Requirement and implement that BADI .
Initial Just Hard Cord break Points in the Method and Exceute the T-Code.
You can use enhancement MM06E005 (read the documentation using transaction code SMOD), include EXIT_SAPMM06E_012.
