Find next dated transaction for same customer

[General Ledger]

I have a table of transactions that include Date and Customer ID. How can I find for a transaction, the next transaction for the same customer?

For example, a customer might have several transactions over several dates. If I look at any one of those transactions, I need to find the very next dated transaction for the same customer.

Date-------Next Date
1/1/19----1/15/19
1/15/19---2/2/19
2/2/19----2/3/19
2/3/19----(blank)

Thank you.

maybe post representative example with structure of the data
or
try group and max date

I understand format date is m/d/y ?
