Error during copying from contract to std sales - Message no. V2 005

Question

Dear Experts,
      My client requirement is, "Qty Contract" needs to be created in the name of one Sold To Party (e.g. XYZ). After that, in the regular sales order screen after entering another Sold To Party code (e.g. ABC) the previously created "Qty Contract" needs to be referred.
                When we tried to create the regular sales order for another Sold To Party (e.g. ABC) by referring the "Qty contract" created we are getting the error message that "The sold-to parties are different. 19991 and/or 99992 (reference)"  Message no. V2005
Can any experts help us to resolve this issue.
Thanks in advance
Warm Regards,

Answer 1

Dear Experts,
         Thanks for your valuable feedback.
But due to my client business requirement, we are looking for the solution as we told in our initial question. But we got the  confident by seeing the "Message" we received during our process from SAP system. In that message its mentioned that, If Business wants the "Error" message can be modify as "Warning". So we are looking for the solution where to modify this error message in to Warning message.
Please find below the system message we received during our testing
The sold-to parties are different. T-L63C01 and/or T-S62A01 (reference)                                                                               
Message no. V2005
                                                                                Diagnosis                                                                               
The sold-to party in the reference document is not the same as the      
    sold-to party in the target document.                                                                               
System response                                                                               
Depending on the copying requirements for the various sales documents   
    which are defined in Customizing, this message appears either as an     
    error message which requires a correction or a warning which can be     
    skipped over.                                                                               
Procedure                                                                               
Procedure for                                                                               
-   Error message                                                    
      Select a suitable reference document which has the same sold-to  
      party as the target document.                                                                               
-   Warning                                                          
      Proceed as described for the error message or skip over the      
      warning with ENTER.                                              
      If you skip over the warning, only the item data from the        
      reference document is copied into the target document.
