Source Field Type string

Other versions: 7.31 | 7.40 | 7.54

Numeric Target Fields

Target Conversion
i, (b, s) Content is handled in the same way as a sourcefield of type c If the source field has a length of 0, the target field is assigned the value 0.
p Content is handled in the same way as a sourcefield of type c If the source field has a length of 0, the target field is assigned the value 0.
decfloat16, decfloat34 Content is handled in the same way as a sourcefield of type c If the source field has a length of 0, the target field is assigned the value 0.
f Content is handled in the same way as a sourcefield of type c If the source field has a length of 0, the target field is assigned the value 0.


Note

  • The CL_ABAP_DECFLOAT class contains the methods READ_DECFLOAT34 and READ_DECFLOAT16, to convert character strings into floating point numbers. The exceptions of these methods are more significant than those of a normal assignment. Furthermore, the methods return a return value that reveals information about the roundings carried out.

Character-Like Target Fields

Target Conversion
c The content is handled in the same way as a sourcefield of type c, with the difference that trailing blanks are passed. If the length of the source field is 0, the target field is padded with blanks.
string No conversion takes place. After the assignment, the internal reference of the target field pointsto the same string as the source field. A new string is only created in the memory if a change request for the content of the source field or target field is submitted.
n Content is handled in the same way as a sourcefield of type c If the length of the source field is 0, the target field is padded with the character "0".
d The content is handled in the same way as a sourcefield of type c, with the difference that trailing blanks are passed. If the length of the source field is 0, the target field is padded with the character "0".
t Content is handled in the same way as a sourcefield of type c If the length of the source field is 0, the target field is padded with the character "0" and the trailing blanks are passed.


Notes

  • In ABAP, the trailing blanks are respected for source fields of type string but not for data objects of type c.

  • If characters are cut off on the right when character strings containing non-Unicode double-byte characters are assigned, such a character can be split down the middle, which generally produces an invalid character at the right edge. To prevent this, the method CL_SCP_LINEBREAK_UTIL=>STRING_SPLIT_AT_POSITION can be used.

Byte-Like Target Fields

Target Conversion
x Content is handled in the same way as a sourcefield of type c If the length of the source field is 0, the target field is padded with hexadecimal 0.
xstring Content is handled in the same way as a sourcefield of type c If the length of the source field is 0, the length of the target field is also 0 after the assignment.
