Mark intervals between an N and P flag with a buffer of X columns

[John2275]

Hi all,

I have a data set with specific N and P flags in a column. I would like to isolate/mark (with a 1) the rows in between NP flag pairs only when the P flag occurs after a minimum of 6 rows, inclusive of the N flag row. Only an N flag after a P flag will create a new isolation interval.

Value	Flag	Mark
234	N	1
234		1
23	N	1
4	P	1
458		1
45		1
8	P	1
58
567	P
...
	N	1
		1
	P	1
		1
	N	1
		1
	P	1
	N	1
		1
		1
		1
		1
	P	1
		1
	P	1

Any and all help would be appreciated. I tried using the filter tool with the multirow formula but I am having trouble figuring out the 6-row margin part. Thanks in advance!

You should be able to accomplish that using a Record ID tool first then use the Record ID as reference for your formula.

Not sure if I'm following exactly what you're looking for but does this somewhat solve?  I acutally increment the mark and reset each interval.
