/AWS1/CL_QSTLOGICALTABLE¶
A logical table is a unit that joins and that data transformations operate on. A logical table has a source, which can be either a physical table or result of a join. When a logical table points to a physical table, the logical table acts as a mutable copy of that physical table through transform operations.
CONSTRUCTOR¶
IMPORTING¶
Required arguments:¶
IV_ALIAS TYPE /AWS1/QSTLOGICALTABLEALIAS /AWS1/QSTLOGICALTABLEALIAS¶
A display name for the logical table.
IO_SOURCE TYPE REF TO /AWS1/CL_QSTLOGICALTABLESOURCE /AWS1/CL_QSTLOGICALTABLESOURCE¶
Source of this logical table.
Optional arguments:¶
IT_DATATRANSFORMS TYPE /AWS1/CL_QSTTRANSFORMOPERATION=>TT_TRANSFORMOPERATIONLIST TT_TRANSFORMOPERATIONLIST¶
Transform operations that act on this logical table. For this structure to be valid, only one of the attributes can be non-null.
