Hello,
I am trying to enhance custom screen Sales: Sales Org. Data 1 in MM02/MM03 transaction.
I have added append structure in table MVKE, copied standard function group MGD1 to custom ZMGD1 and also added screen sequence in SPRO.
I have added two radio buttons and assigned function code to them,
Screen is now visible in MM02/MM03 transaction, but getting this error if I click on radio button 'Record 21 ____ does not exist in table T133E'.

Am I missing any step?
I have followed blog Enhancing Material Master.
Thank you.
