Dear Ravi
the issue is the "list of customers" who would like to get sequence number. This is in most cases not a "static list" but dynamic. Therefore you need to find a way to handle this list of "customers". As you now: a customer is maintained using a "business partner". And you need to be specific which role you would like to use to do so. If you do not have a problem in generating customer specific report symbol: you could try to use an own symbol with output condition (blank compression e,g,): if in the "delivery" on of the customers is mentioned which should get ssequence number you would print; in the othere case you use blank compression and you would not print (or use if/eks technique; here the same result comeup).
