Further Changes in 7.0, EhP2
3. New API for Generating UUIDs
6. Class for Generation Limits
7. Splitter Control on Dynpros
Other versions: 7.31 | 7.40 | 7.54
Modification 1
Lossless Assignments
The new addition EXACT of the
statements MOVE and MOVE-CORRESPONDING enables
lossless assignments; if data is lost or values are invalid, an exception is raised.
Modification 2
New RTTC Methods
The new GET method of classes CL_ABAP_STRUCTDESCR, CL_ABAP_TABLEDESCR, CL_ABAP_REFDESCR sowie GET_BY_NAME of class CL_ABAP_REFDESCR return the type object specified by the input parameter. A new type object is generated or an existing one is used again.
Modification 3
New API for Generating UUIDs
The methods of class CL_SYSTEM_UUID generate UUIDs in various formats, such as 16-character byte-like UUIDs, 22-character character-like UUIDs with upper and lower case letters, and 32-character character-like UUIDs in hexadecimal format. They also permit UUIDs to be converted to one another.
Modification 4
New Time Formats
While number and date formats for outputs have always been formatted according to the formatting setting of the language environment, until now only the 24-hour format has been available for time outputs.
From SP14 in Release 7.0, four additional 12 hour formats have been introduced. These formats can be selected in the fixed values in the user master record or stored specifically for each country in a new column TIMEFM in the T005X database table.
If enough space is available, a time is displayed on the dynpro in 12-hour format when the relevant settings are made in the user master record.
In ABAP, new formats can be used by means of the new
ENVIRONMENT TIME FORMAT addition of the WRITE TO and WRITE
statements as well as by using the
environment and COUNTRY formatting options for
embedded expressions in character string templates.
The new class CL_ABAP_TIMEFM contains methods for converting between external and internal times, as well as some auxiliary methods.
The predefined time formats of the WRITE
TO and WRITE statements cannot be influenced automatically due to downward compatibility.
Note
The new formats are supported on dynpros and in Screen Painter from EhP2.
Modification 5
String Constants in PXA
From Release 7.0, EhP2, strings declared as constants are saved globally in PXA in the same way as all constants. This can significantly reduce the amount of memory required.
Modification 6
Class for Generation Limits
From Release 7.0, EhP2, the static method GET_VALUES of class CL_ABAP_GEN_LIMITS returns the generation limits for an ABAP program.
Notes
This change was previously introduced in Release 7.0, SP16.
Modification 7
Splitter Control on Dynpros
From Release 7.0, EhP2, splitter controls can be used on classic dynpros. A splitter control enables two subscreens to be arranged above and below or beside one another in a way that allows the border between the subscreen areas to be moved.
Modification 8
Extended Jump Distance
Prior to Release 7.0, EhP2, errors could occur in ABAP programs in which jump distances were too large.
This could also occur, for example, if processing blocks were exited with RETURN,
since this statement jumps to the end of the block. From Release 7.0, EhP2, the jump distance is essentially unlimited.
Note
The unlimited jump distance should not be exploited intentionally. It enables errors to be prevented in large procedures or control blocks, but the maximum recommended number of statements in a procedure should always be adhered to as outlined in the programming guidelines.
Modification 9
Dynamic Programming
The documented class CL_ABAP_DYN_PRG provides a set of static methods that support error-free, secure dynamic programming.
Modification 10
File Interface
The documented class CL_FS_PATH provides a set of static methods that support the error-free, secure handling of file names.
