Enhancement in ME22N

Question

Hi All,
         There is requirement to enhancement in  Release strategy (ME22N). If  user increase the OP price the release strategy being changed but he decrease the OP the price release strategy not being changed. The reauirement is there if they make any change in OP price either incrase or decrease, release strategy should be change. therefore there is any User-Exit or BADI which change the release strategies related informantion. I have aslo tried some user exit and BADI but in these exit and BADI  the OP header information not in export parameters (this information is import parameters) so I can not make change it. there is any other user exit or BADI for do that.
Thanks in Advance

This is mainly config.
Check in SPRO - IMG
Materials Management > Purchasing > Purchase Order > Define Screen Layout at Document Level
Also these BAdis are available:
ME_PROCESS_PO_CUST - For Custom logic in Enjoy transactions
ME_GUI_PO_CUST - For Additional Custom screens in ME2xn
Read the documentation, it will help.
Also, read the config section about enhancements in Purchasing using old enhancement technology. See below.
OSS is also a good place for documentation. OSS 496083.
Good luck!

     In contrast to modifications, enhancements are basically
     release-insensitive since they are not implemented in the SAP original
     but in a name range that is reserved for the customer.
     The general procedure for creating enhancements can be found in the
     enhancement transaction at Help -> Application help.
     If you want to display the documentation for an enhancement, choose Goto
