if Statment with previous or any other suggestion

Hi guys

i have some sampledata but i cant get my If statment to work properly. It's a bit complicated but maybe somebody can help me out

This is the sample below

I want to know if a customer bought a Product in the 100 series and at the same date or six months before bought he/she bought a Product in the 200 series . Can I solve this with a IF statement and a PREVIOUS statement? or is there any other sulotion that's better to solve this problem?

thx Theo

Re: if Statment with previous or any other suggestion

I'm not sure if you could get it to work with previous/peek-functions within if-loops because you would need to define how many iterations are max. possible and to sort your table to all of your conditions. I would probably try to get this informations with join/keep-loadings like:

table1:

load Customer, Date from Source where Product = '1??';

     concatenate(table1)

load Customer, addmonths(Date, -6) as Date from Source where Product = '1??';

inner join(table1)

load Customer, Date from Source where Product = '2??';
