3 Storing of interface constants
4 Exception handling for data clusters
5 Authorization check for users
6 Strings on selection screens
7 Format of lists when sending


ABAP_MODIFICATION_1 Class for system statuses

The static methods of the class
CL_ABAP_SYST return important system statuses and replace the evaluation of the corresponding system fields if you need to ensure that a system field has not been incorrectly overwritten in a program.


ABAP_MODIFICATION_2 Number of main sessions per user session
From Release 7.0, up to 16 main sessions
can be opened per user session, compared to the previous maximum of 6. The actual number is controlled by the system parameter
rdisp/max_alt_modes . The standard value for this parameter is 6 as before.
To enable more than single-digit numbers in the system field sy-modno , its data type has been changed (incompatibly ) from c of length 1 to i
.


ABAP_MODIFICATION_3 Storage of interface constants
From Release 7.0, an interface constant is created exactly once in the internal session and GET REFERENCE returns the same reference regardless of the name. Before Release 7.0, a new interface constant was created for each implementation and different formulations like
i1= const , c1= i1~const , or c2= i1~const resulted in different references for a constant const with GET REFERENCE
.


ABAP_MODIFICATION_4 Exception handling for data clusters

In IMPORT , the exception IMPORT_FORMAT_ERROR has been made handleable by assigning it to the new class CX_SY_IMPORT_FORMAT_ERROR . The exception CONNE_IMPORT_CONVERSION_ERROR has been made handleable by assigning it to the existing class
CX_SY_CONVERSION_CODEPAGE (change was also transported back to Release 6.40)
The addition IGNORING CONVERSION ERRORS
now also suppresses the exception raised by the fact that the number of bytes of an imported character-like component increases when it is converted to another code page, and therefore no longer fits into the target object. Up to now, only superflous blanks were cut off without raising an exception (change was also transported back to Release 6.40).


ABAP_MODIFICATION_5 Authorization check for users

From Release 7.0, the statement
AUTHORITY-CHECK now has the addition FOR USER , which can be used to check the authorizations of any user.


ABAP_MODIFICATION_6 Strings on selection screens

In the statement PARAMETERS , it is now also possible to specify the data type string after the addition TYPE .


ABAP_MODIFICATION_7 Format of lists when sending

The internal format into which an ABAP list is packed when the
send function is called, has been changed. The previous format can still be read. From Release 7.0, in order to send lists to systems with older releases, the new format must be converted to the previous format using the function module LIST_CONVERT_TO_OLD_FORMAT .
