This table type has a line type of LVC_S_FCAT. Internal Table such as the fieldname, column position, etc. This structure is used to maintain the attributes of each field of the Dynamic Others = 2 Structure for Dynamic Internal Table Creation The class CL_ALV_TABLE_CREATE and the method CREATE_DYNAMIC_TABLE.Įxceptions: generate_subpool_dir_full = 1.Dynamic internal tables can be created using : To access the contents of the data object to which a data reference is pointing, you must dereference it.ĪSSIGN ->* TO. To create a data object dynamically during a program, you need a data reference variable and the following statement: You can create a data reference variable by using: You can only dereference a data reference using a special assignment to a field symbol. You can also create references to existing data objects. You can use data references to create data objects dynamically. ĭata references are pointers to data objects. You declare the field symbol using the statement FIELD-SYMBOLS. This means that all changes to the contents of f are visible in and vice versa. The field symbol then "points" to the contents of field f at runtime. The statement ASSIGN f to assigns the field f to field symbol. Set a pointer to a data object that you determine at runtime (dynamic ASSIGN) Set the offset and length for a string variably at runtime They are similar to dereference pointers in C.Īdopt or change the type and size of a data object dynamically at runtime (For the remaining attributes please refer the ABAP structure LVC_S_FCAT) Prerequisites of dynamic internal table areįield symbols are placeholders or symbolic names for other fields. Some of the important attributes of an internal table which can be set dynamically are Extremely useful when the numbers of columns / fields are not known at the design time / compile time.Some of the benefits of Dynamic internal table are: Dynamic internal Table A Dynamic Internal Table is an internal table with variable number of rows and columns, which can be defined during run time only.Ī dynamic internal table is not declared in the program as static.
