hi,

Please see the following declaration,

TYPES :BEGIN OF WA_ADMN_MAS.

TYPES :SEL TYPE CROSS-TYPE.

INCLUDE STRUCTURE ZTRST_ADMN_MAS.

TYPES :END OF WA_ADMN_MAS.

why did they write TYPES :SEL TYPE CROSS-TYPE.

what is the use of the statement.

please revert backas soon as possible

Thanks & regards,

Kirthi

What they are defining here is that the structure should have all fields of ZTRST_ADMN_MAS as well as another field call SEL. Most likely this SEL field is the selection handling field for maybe a table control or ALV grid.

Hi Kirti,

TYPES :SEL TYPE CROSS-TYPE.

denotes declaring a variable which is of the type Field:<b>TYPE</b> from Table:<b>CROSS</b>. It is basically a Single-Character Indicator.

Reward if useful.

Thanks

Because it added a new field, not included in dictionary structure (or table) ZTRST_ADMN_MAS, in the type defination.

When the INCLUDE STRUCTURE is used to declare a structure, the first statament has to end with a point, so or you write:

TYPES : BEGIN OF WA_ADMN_MAS.
TYPES : SEL TYPE CROSS-TYPE.
                INCLUDE STRUCTURE ZTRST_ADMN_MAS.
TYPES : END OF WA_ADMN_MAS.

TYPES : BEGIN OF WA_ADMN_MAS,
                SEL TYPE CROSS-TYPE.
                INCLUDE STRUCTURE ZTRST_ADMN_MAS.
TYPES : END OF WA_ADMN_MAS.
