CX_TRANSACTION::SuccessorsOfTopType

CX_TRANSACTION::SuccessorsOfTopType

Description:

This function returns all successors whose TopTransaction belongs to a specific class. This class can be specified via the first STRING parameter. The first INTEGER-parameter ("inherited") controls whether successors are also to be taken into account whose TopTransaction are of a class derived from the specified class. The second INTEGER-parameter ("maxLevel") controls how far the successor chain is followed at most.

The following two calls are essentially identical in their semantics:

Get(SuccessorsOfTopType("CX_SALES_ORDER", FALSE, 0xFFFFFFFF))

Get(SuccessorsByCondition("type(TopTransaction())=CX_SALES_ORDER", 1))

SuccessorsOfTopType thus also searches the subTransactions (see mode 0 for SuccessorsByCondition), but does not add any TopTransactions itself.

Code example:

FString(NONE::call(GetSalesOrder).uniqueID, NO_PRINT, TOOLTIP("Nach Auftrag suchen", "Search by sales order"), 490, 10, 90, "000000", "000000")
[ SELECT: Var(nr)
          GetValue -> nr
          nr Integer ifnot return
          ClearObox(, ListBox)
          [ "uniqueID" ] SetSort(, ListBox)
          BeginTXN(READ)
          CX_PURCAHSE_ORDER  // Klassenname
          0                  // Ableitungen berücksichtigen
          1                  // zu durch suchende Tiefe
          nr "uniqueID = %s" FindFirst(CX_SALES_ORDER) Dup ifnot { Drop return } // Transaktion
          Call(SuccessorsOfTopType) iterate
          { Get(TopTransaction()) UpdateObox(, ListBox) }
