Hi I'm new here, I'd like to ask if anyone knows why when the user reverse an IC from work order completion using P31114, by changing the quantity to negative, the item ledger has record of the stock quantity being deducted but the unit cost of that record is 0?

I've read that if the item does not use standard cost then the reversal would not work but I checked the item, the cost method is 07 Standard.

Any other possible root cause for the zero unit cost in item ledger record? Appreciate any help on this.
