LSMW -Measuring Point Lower limit set as zero

Hi,

I am cretting measuring points through LSMW and while uploading the data i found that system is not updating the value of lower range limit in Additional data Tab.i have gone through suggestion given by experts to flag the Negative Vals Allowed in Characteristic basic data but our business persons are not ready for flagging field  Negative Vals Allowed as they do not want to allow any negative Value.

Is there any solution to create the measuring points with upper and lower limit without flagging  Negative Vals Allowed in characterisitc.Please note that business person has to create measuring points in huge numbers so we cannot suggest them to create manually with Transction Code IK01.

Thanks
