Difference between length and output length of a data type in SAP

[former_member596118]

I've seen this article

https://help.sap.com/doc/abapdocu_731_index_htm/7.31/en-US/abenwrite_output_length.htm

but I still don't quite understand what the output length is trying to achieve for a data type or a domain. The length is fairly straightforward and indicates how many characters or numerals the type has but the output length is unclear.

Output length is maximum length of the field i.e. including comma and period

[Sandra_Rossi]

Try to learn the magic with the domain "SPRAS" (language code), it's 1 character in database tables (e.g. "D" if it's german) but when displayed, it appears on 2 characters (e.g. "DE").

You should first perform your own search at help.sap.com for "external and internal format". Then consider date, time, numeric, amount, quantity type fields and at last notion of conversion exit.
