Source Code

REPORT demo_dynpro_set_hold_data.

DATA field(10) TYPE c.

CALL SCREEN 100.

field = 'XXXXXXXXXX'.

CALL SCREEN 100.

MODULE hold_data OUTPUT.
  SET HOLD DATA ON.
ENDMODULE.

Description

The static next dynpro of dynpro 100 is 0. It contains a single input/output field field. The dynpro flow logic is:

PROCESS BEFORE OUTPUT.
  MODULE hold_data.
PROCESS AFTER INPUT.

In the PBO event of the dynpro, the Hold Data attribute is activated regardless of the static default. If, after entering a value, the user chooses System → User Profile → Hold Data or Set Data, the value is displayed again when the dynpro is called a second time and whenever the program is subsequently called (in the same ABAP session) unless the user chooses Delete Data. This overwrites any value assigned to the field field in the ABAP program.
