Vendor User Exit at Initial Screen

Question

Dear friends
When a vendor is created through XK01, I would like to control that if u201CAccount Group 1000u201D is entered then Purchasing Organization and Company Code fields must be mandatory before skipping them empty at initial screen. Although I found a user exit that controls the data on saving but itu2019s too late since after creation of vendor workflow will be triggered and until itu2019s approved no changes will be allowed.
Looking forward to your advice and thanks in advance.
Thanks and Best Regards,

Hi,
Following are userExits of T-code XK01,
RFKRRANZ            User exits: Accounts Payable Information System
SAPMF02K            User exits: Vendor master data
To Activate User Exit or Implement it,
Use T-CODE CMODE.
First Check whether enhancement is assigned to a project in CMOD.
If it is not assigned, then  assign it to a project by creating Project in T-Code CMOD.
After Assign Enhancement in project click on Components Button on Application bar of CMOD.
Click on Function Exit and Active the Include present in USER EXIT.
Write Your Code in the include fresent in UserExit.
There is a Active button at application Bar of T-code in CMODE  to activate the exit.
Thanks & regards,
