Thank you for the reply vadim,
The requirement is to plan for new cities of business along with existing cities. The client insists for all the cities to be seen as per the selection criteria of "Region" ans "Sales group".
The maximum length of the dimension is "31". It is not taking characters after that. Still i have some duplicates because of length issue, system is taking 31 characters and leaving the remaining.
If some how i shorten the name of the city manually, then i think there might be problems when transaction data load like "Population", etc. will be difficult to match the master data.
Thanking you
Praveen
