Hello, the output is correct for the alpha conversion. See extract from doc how the alpha conversion works:
When converting from an external into an internal format this checks whether the entry in the INPUT field is wholly numerical, whether it consists of digits only, possibly with blank spaces before and/or after. If yes, the sequence of digits is copied to the OUTPUT field, right-aligned, and the space on the left is filled with zeros (‘0’). Otherwise the sequence of digits is copied to the output field from left to right and the space to the right remains blank.
For conversions from an internal to an external format (function module CONVERSION_EXIT_ALPHA_OUTPUT) the process is reversed. Blank characters on the left-hand side are omitted from the output.
