How could I divide one multiple_value field into multiple different value?

[Jennifer]

Hi, all!

How could I separate this filed into many other fields which is formed by 4 characters?

For example:

The original value
31381012204777027704	3138	1012	2047	7702	7704
3138111620941002204720387701W019	3138	1116	2094	1002	2047	2038	7701	W019

To create a multi-value field, you could do this

| rex max_match=0 field=Call_Sequence "(?<four>.{4})"

Thanks so much for your help!

It solves part of the problem! How could I make the new results become three separate rows?
