Lookup tool

[JBO]

I would love a tool to be created for looking up a value in a table based on a condition. It could be called "Lookup." One input to the tool would be the lookup list, the other is the main database. Inside the tool you could enter functions that can query the lookup table and return the results either as an overwrite of an existing field in the main DB or as a new field in the main DB, similar to the options in the Multi-Row Formula tool.

Here is a link to my post in Community that explains the problem. The solution, in a nutshell, was to create a Join (which resulted in millions of additional rows), run the conditional formula, then filter to get rid of the millions of rows that were created by the Join so only those that met the condition remained (the original database rows).

Here is the text of my Community post describing my project (slightly modified for clarity):

Table 1:  A list of Pay Dates (the lookup table)

Table 2:  Daily timekeeper data with Week Start and Week End Date fields.

The goal:  To find the Pay Date in Table 1 that is greater than the Week Start Date in Table 2 and no more than 13 days after the Week End Date in Table 2.

[Table 2: Week Start Date] < [Table 1: Pay Date]

and [Table 2: Week End Date] < [Table 1: Pay Date]

and DateTimeDiff([Table 1: Pay Date], [Table 2: Week End Date], 'Days') <= 13

There are many different flows I could use this type of tool for that would save time and simplify the flow.

Thanks!
