Input mask Choose input mask when the value has a stable, narrow structure with predictable character classes and grouping. Typing valid characters fills the next available mask slot and inserts literal separators automatically. SAP Fiori supports mandatory labels, mask patterns, immutable characters, aria-described guidance, paste behavior, deletion behavior, and mask avoidance when valid data would be blocked.
