It's data entry error that someone mistyped the amount of one parts needed to make one model of goods... in ten folds of the actual needed number.
This somehow had gone unnoticed originally, but when they use past data to check my calculation, the problematic data become quite visible. While this parts was in small quantity for each piece of goods, it is quite expensive, someone have to take the responsibility for this.
I was willing to play low profile for this by plainly say the ordered quantity is made 10 folds too, the number for this field will be okay, and hope to let it sneak past without raising management's attention (it sounds as if that's one of the many "data entry" problem previously pointed out). But one other merchandiser, don't know whether she had bad relationship with the original one or not, or maybe just try to point to every possible bug to resist using the new form, jumped in and said it's not acceptable, and make me have to explain the actualy nature of "the bug", and in the end the management choose to fire the original merchandiser because of this.
That's the end of story.
