Sometimes,  we need to validate some inputs from users that are inserted by external sources (like files).

For this purpose, we found very useful function modules like CONVERT_DATE_TO_INTERNAL and CONVERT_TIME_INPUT to validate external dates formats and external times formats (ex: dates like ’24.06.1978′ or times like ’11:00:00′)

This functions are also very useful to convert the external information to internal information.

If you need more conversions of this kind, take a look at utility class CL_ABAP_DATFM.

Check if is helpful for you too, or if you have any other suggestions feel free to share with us!
