Hello Roshan,
There is no such standard tcode available for users to view external number range for RFQ, PO, PR, Matreial....
Option 1:
Users creating RFQ for the 1st timeWhat you can do is goto tcode: OMH6.. click on 'Overview'symbol... you can fine number assigned for external range. along with current number .. Try them into your system tcode: ME41...
Note: During Business blue print document all the number ranges are defined in the system as per user requirement for external number range...
Option 2:
If already some RFQs are created in the system and the user is not aware of the next number to be assigned to RFQ, then goto tcode: ME4L, enter your plant and execute, you can view the last RFQ number...
Hope this clears your doubt.. Kindly let me know if you have any query..
