Hi,
if possible, delete master data and reload. Every thing will be right .
As my guess .during project starting time, your team may not be used ALPHA conversion for info object 0IND_CODE.
Later, due to requirement, your team may enabled ALPHA conversion(indo object maintenance screen, General tab).Old data without deletion, team may loaded full data. in such case old data will be exist without leading 0 and new data data will be loaded with leading 0.
Due to that your master data holds two records for one industry code.
Thanks
