SYSTEM-CALL - Editing Internal Tables

Note

*---------------------------------------------------------*
This statement is only for

!!! Internal use in SAP Basis development !!!

Even within SAP Basis, it may only be used in programs within the ABAP+GUI development group.

Its use is subject to various restrictions, not all of which may be listed in the documentation. This documentation is intended for internal SAP use within the Basis development group ABAP+GUI.

Changes and further development, which may be incompatible, may occur at any time, without warning or notice!

Variants:

1. SYSTEM-CALL ITAB_DELETE_LIST TABLE itab1 INDEX-LIST itab2
   
                                        [NO-CHECK].

2. SYSTEM-CALL ITAB_INFO TABLE itab1 OPCODE op
   
                                 {VALUE f|PROTOCOL itab2}.

Variant 1

SYSTEM-CALL ITAB_DELETE_LIST TABLE itab1 INDEX-LIST itab2
                                         [NO-CHECK].

Effect

The system deletes the lines of internal table itab1 whose line numbers are specified in internal itab2.

The table of line numbers itab2 must have the same type as
I and the numbers of the lines that are to be deleted must be unique and in ascending order. That is, itab2 must follow a strict order from line 1 to line n (where line n is the final line of internal table itab2). Otherwise, the system returns a runtime error.

If you declare the optional additionNO-CHECK the calling program is responsible for guaranteeing that itab2 contains only valid line numbers in ascending order.

Variant 2

SYSTEM-CALL ITAB_INFO TABLE itab1 OPCODE op
                                  {VALUE f|PROTOCOL itab2}.

Effect

The system provides information from the header of the internal table itab1. It determines which information is providedfrom the header using the OPCODE field. According to OPCODEthe results are stored either in the field f or in the log table itab2.

The field f must be of type I and itab2 must be a table of the line type C with length 72.

At present, the system supports the following OPCODEs:

'IT_OCCU'

Returns the actual value of OCCURS used in the table itab1 in the field f

'IT_HSDIR'

In the field f, returns the value 1 (if an internal COLLECT hash management for tableitab1 exists) or 0 (if it does not, or if it no longer exists).

'IT_FSREGCNT'

Number of field symbols registered for the table.

'IT_LENG'

Length of line in table

'IT_FILL'

Extent to which table is filled

'IT_GETSTOR'

Writes information about the memory allocated to and used by the table itab1 to the log table itab2.

'IT_TYPE_INFO'

Writes information about the type of the internal table itab1 to the log table itab2. The first three lines contain the CRC64 hash values of the line types, the key definition, and the table type itself. The following three lines contain the values for the table type, the number of key fields, and the uniqueness indicator.

'IT_REF_COUNT'

Reference counter to the shared part of the table header
