Hi,
I have the following challenge where I would ask for your support:
- I have a table that contains account transactions
- I have a (growing) set of "rules", according to which I could assign a specific type to each transaction.
- My main question is how to define these rules in airtable and how to check if they apply and according to the result to set the type for each transaction.
To give an example - see screenshot of such a transaction:

- My rules typically must consists of a "contains" -matching within the column "TAC-Source" and a "contains" -matching within the column "TAC-Description".
- In the case shown in the screenshot, the rule to apply would be "If TAC-Source contains "EG Schottenfeldgasse" and if TAC-Description contains "0704"" then set column Ruleset_MAtch_Type to Value "A"
Defining these rules would work within an automation. Unfortunately they are limited to 50 per base; and I will have more than 50 rules...
I also tried to make a separate rules_table, where each line is a rule and has 3 columns; 1) Stringpart to search for in "TAC-Source" 2) Stringpart to search for in "TAC-Description" 3) the corresponding type value.
Defining the rules would work; but I have no idea how to get them applied, i.e. how to get airtable to check the matching criteria then from the ruleset table to the TACS table.
Anyone with an idea to help? Thank you!!
br Chris
