    Many options. The easiest is to use the replace operator twice, first to replace female with F and then Male with M.

    Another would be to use the generate attribute operator, and use some combined functions.

    You generate the attribute Gender (you actually recreate it) and use prefix(upper([Gender]), 1) for instance.

    However, the canonical operator for this type of replacements is "Map".
