Sure,
If the actual MATNR is 000000000123056789 an I use the code you suggested, i'll retrieve only 3 chars:'567' instead of the expected 4 chars '0567'.
If the actual MATNR is 000000000123456789 I'm getting the correct 4 chars '4567'.
I wish the query to display all the 4 chars even if the first one is zero.
Thank you again for your help!
