Dear varada rajan,

If i understood your question correctly that U need to assign external number range with charecter + number .

If this is correct , then

1. Go to SPRO -- Logistic general -- busines partners - Customer -- control -

A. Define Account Groups and Field Selection for Customers :

copy your existing account group and in general data maintain A1 ( you can mention as per your logic ) .

B.Define and Assign Customer Number Ranges -

i. Maintain CNA1000 to CNA2000 and mark tick in External number range

ii. Assign Number Ranges to Account Groups : here you assign the number range against the account group.

Now , you can create customer number range between

CNA1000 to CNA2000.
