hi,

With data types p, n, c, and X you can enter a length in parentheses after the type name. If no length

is entered, the default length for this data type is used.

With data type P you can use the DECIMALS addition to determine the number of decimal places that

should be used (up to a maximum of 14). If this addition is missing, the number of decimal places is

set to zero.

If you do not specify a type, then the field is automatically type C.

All other literals (character, numbers with decimal places, floating point numbers) are stored as text

literals with data type C. If a literal is assigned to a variable that does not have type C, then a type

conversion is carried out.

The length specification after the type name for ABAP data types C, N, and X specifies the number of

characters in the type. For type P fields, you can also set the number of decimal places. If you omit

these specifications, the system uses the default values

Hope this helps, Do reward.
