BOM DistributionLine Error

SOLVED

Hi,

I've been wondering for a couple of days now. it seems that the Distribution line is adding a bunch of numbers on my Lot.

 retVal = oProduction.oLines.oDistribution.nAddDistributionLine("B456")

oProduction.oLines.oDistribution.sLastErrorMsg says: "The 0000374000001B456 is invalid"

Cant seem to figure out where the "0000374000001" is coming from.

Hoping to shed some light on this error;
