To create a simple sequence, the next_in_sequence() function can be used in a reformat.
In order to get cumulative summary, temporary variables can be used iteratively to increment a particular column by adding the previous value with the current value incrementally.
If a Key is involved, we need to ensure that the Key is sorted before the Reformat. A key change function using variables need to be written such that if the Key's current value is not equal to the previous value, the group has changed and the cumulative total needs to begin again with the current record value. If multiple columns make a key, the values can be concatenated for the key change verification.
