EAN11 - MEAN Table - Issue with leading Zero's

Hi

Need an help on EAN11 field , We have a requirement to accept EAN11 number with leading zeros and that value will be vary . Not sure how many zeros a number will be ( Ex: 0012345 or 00012345 or 012345) , the fixed length is 12.

Here the issue is while entering EAN number in MM01 / MM02 with leading zero , The value is getting truncated and always shows without leading zero's.

We have done configuration changes by adding EAN length / Checked Alphanumeric . But no use.

Please suggest.
