Hi, Renate.
It took me a while to answer because I needed to test on a base what you reported.
I don’t know if I went in the same place as you, but using Export by Text and putting “R” in the “Repeat separator” field worked for me.
In my test I put 2 values in a field:
Example:
^a123456789
^a987654312
On export it came out:
^a123456789; ^a987654312
The semicolon can easily be replaced, but ABCD managed to export the repetition.
