I do usually encounter the kanji 引当 but I suddenly encountered the 引充 kanji. My colleague said they mean the same and their reading is the same. when do you use the one over the other?
The word that the kanji modified that time 引充ｷｬﾘｱNo. which is a normal cart in an assembly line. why is the kanji more appropriate that the commonly used 引当 that time?
