Order prefix/Order suffix options let you use a prefix/suffix in the order IDs. Numeration will remain progressive, but each ID will have the indicated text before/after.
Let’s assume to set “YITH-SX” as a prefix and “-YITH-DX” as a suffix: the ID will be like in the following image.
The available placeholders to use in the prefix or suffix are:
[D] Day without leading zeros
[DD] Day with leading zeros
[M] Month without leading zeros
[MM] Month with leading zeros
[YY] two-digit year
[YYYY] Full year
[h] 24-hour format of an hour without leading zeros
[hh] 24-hour format of an hour with leading zeros
[m] Minutes with leading zeros
[s] Seconds, with leading zeros
