I have a dataset to which I need to apply some mappings.
However, I can't use the join tool on its own for this as the mappings are based on some/all fields depending on whether an asterisk has been recorded (essentially acting as a sort of wildcard).
Here is what the mapping table looks like:
Looking at the first mapping as an example, we'd need A, B, D and E to match in the dataset, returning 'TEXT1' if so. C and F can be any value. If TEXT1 doesn't return a match, we'd need to check the second mapping.
This mapping table can grow, so it needs to be valid for all possible combinations.
Adding a record ID then appending the entire mapping table to the dataset, using some formulae to work out if there's a match followed by a find and replace against the record ID back to the original data.
