How to evaluate a field over multiple rows. Trying to create variable.

Hello!

I'm working with data for customers where one of the fields is saved in the originating software as a table. I need to be able to evaluate the entries in this field as a group for each customer. I'm having a bear of a time trying to figure out how to create the variable so it gives me what I need.

I'm not able to work with SQL so I'm limited to what is available within the Webi variable builder.

This is an simplified example of what I'm looking at:

Customer#   Date          Document

1                   5/8/2015    Receipt

1                   5/8/2015    Order

1                   5/8/2015    Delivery

I need to create a variable that puts all the documents together so I can then create some formatting rules based on the variable.

For example. If the variable gives me [Receipt, Order, Deliver], I can create a rule that says "If [variable] matches "*Delivery*" and not [variable] matches "*Receipt*"] then 1 Else 0". From there I can tell the system to highlight each entry where this rule is true as red.

I'm working with about 15-20 documents per customer. The document types are never in the same order so I can't use the previous function.

Any suggestions you may have would be most appreciated.

Thanks!
