hi,

The statement

SELECTION-SCREEN DYNAMIC SELECTIONS FOR NODE|TABLE <node>.

declares a node <node> of a logical database for dynamic selections in the selection include.

To use the dynamic selections in the SELECT statements of the subroutine PUT_<node>, you must use the data object DYN_SEL. The data object DYN_SEL is automatically generated in the logical database program as follows:

TYPE-POOLS RSDS.

DATA DYN_SEL TYPE RSDS_TYPE.

You do not have to program these lines yourself. The data object DYN_SEL is available in the database program but not in a connected executable program.

The type RSDS_TYPE of the data object is defined in the type group RSDS as follows:

TYPE-POOL RSDS.

• WHERE-clauses ------------------------------

TYPES: RSDS_WHERE_TAB LIKE RSDSWHERE OCCURS 5.

TYPES: BEGIN OF RSDS_WHERE,

TABLENAME LIKE RSDSTABS-PRIM_TAB,

WHERE_TAB TYPE RSDS_WHERE_TAB,

END OF RSDS_WHERE.

TYPES: RSDS_TWHERE TYPE RSDS_WHERE OCCURS 5.

• Expressions Polish notation ---------------

TYPES: RSDS_EXPR_TAB LIKE RSDSEXPR OCCURS 10.

TYPES: BEGIN OF RSDS_EXPR,

TABLENAME LIKE RSDSTABS-PRIM_TAB,

EXPR_TAB TYPE RSDS_EXPR_TAB,

END OF RSDS_EXPR.

TYPES: RSDS_TEXPR TYPE RSDS_EXPR OCCURS 10.

• Selections as RANGES-tables -----------------

TYPES: RSDS_SELOPT_T LIKE RSDSSELOPT OCCURS 10.

TYPES: BEGIN OF RSDS_FRANGE,

FIELDNAME LIKE RSDSTABS-PRIM_FNAME,

SELOPT_T TYPE RSDS_SELOPT_T,

END OF RSDS_FRANGE.

TYPES: RSDS_FRANGE_T TYPE RSDS_FRANGE OCCURS 10.

TYPES: BEGIN OF RSDS_RANGE,

TABLENAME LIKE RSDSTABS-PRIM_TAB,

FRANGE_T TYPE RSDS_FRANGE_T,

END OF RSDS_RANGE.

TYPES: RSDS_TRANGE TYPE RSDS_RANGE OCCURS 10.

• Definition of RSDS_TYPE

TYPES: BEGIN OF RSDS_TYPE,

CLAUSES TYPE RSDS_TWHERE,

TEXPR TYPE RSDS_TEXPR,

TRANGE TYPE RSDS_TRANGE,

END OF RSDS_TYPE.

CLAUSES

CLAUSES contains the dynamic selections entered by the user (or possibly program-internal selection criteria) as internal tables, which you can use directly in dynamic WHERE clauses.

CLAUSES is an internal table that contains another internal table WHERE_TAB as a component. Each line of the CLAUSES-TABLENAME column contains the name of a node designated for dynamic selections. For each of these database tables, the WHERE_TAB tables contain the selection criteria of the dynamic selections. The WHERE_TAB tables have a format that allows you to use them directly in dynamic Where.
