Here's what I'm trying to accomplish in a script:

-Import data into FILE B from one record in a found set in FILE A.

-In order to import only that one record, I am *omitting* that record in FILE A and then using the "Show Omitted" script step. The ensuing Import Records step then correctly imports only that one record.

What I can't figure out is: At the end of the script, how do I then go back and restore the previous found set in FILE A to the exact state it was in before, sorted in the same order as before, and make the 'omitted' record the current record being browsed? Hope that makes sense. Any suggestions greatly appreciated.

If you don't have too many records in the found set, the Copy All Records script step can be used to copy the IDs of the found set, which can then be stored in a global. Then a Go to Related Records [ Show ] step on a self-join relationship from the global to the ID should produce the correct found set. You would then use one more GTRR on a self-join from another global LastID to ID relationship to navigate to the correct record.

See my demo in this thread:

The size of the found set you can remember with this is limited to maximum number of characters allowed in a text field (something like 64,000 characters, or a few thousand records depending on the size of the ID.)

Another approach would be to pass the data from A to B via global fields. If there are only a few fields that would be easy enough. If there are a lot of fields, then set a global in B to the primary key of A, and make a relationship in B from the B global to the A key field, then set the fields in B based on the relationship.
