Hi Priya,

Try makinng the fields in the 2nd button inactive.I think this should work, had done earlier.

In AT selction-screen event,

call Loop at screen.

Based on screen-name, make the field as inactive.

i.e., screen-active = 0.

If it works, assign points pls..

Thanks,

Hi Priya,

1)Remove the mandatory option from the definition.

2)In the event

AT SELECTION SCREEN ON BLOCK

check if the parameter is initial and display a error message.

Hi,

Consider this program.

REPORT  zzarun_pass.

PARAMETERS : one RADIOBUTTON GROUP ab DEFAULT 'X',
             second RADIOBUTTON GROUP ab.

SELECTION-SCREEN BEGIN OF BLOCK abc WITH FRAME.
PARAMETERS : p_unam1(20) TYPE c,
             p_pass1(20) TYPE c  LOWER CASE .
SELECTION-SCREEN END OF BLOCK abc.



SELECTION-SCREEN BEGIN OF BLOCK efg WITH FRAME.
PARAMETERS : p_unam2(20) TYPE c,
             p_pass2(20) TYPE c  LOWER CASE .
SELECTION-SCREEN END OF BLOCK efg.


AT SELECTION-SCREEN ON BLOCK abc.

  IF one EQ 'X'.

    IF  p_unam1 IS INITIAL.
      MESSAGE 'Enter value for p_unam1' TYPE 'E' DISPLAY LIKE 'S'.
    ENDIF.

  ENDIF.


AT SELECTION-SCREEN ON BLOCK efg.

  IF second EQ 'X'.

    IF   p_unam2 IS INITIAL.
      MESSAGE 'Enter value for p_unam2' TYPE  'E' DISPLAY LIKE 'S'.
    ENDIF.

  ENDIF.

Hi all.

thanks for your reply.

iam try to use loop at screen in the vent atselection screen on block, but here field is declared as follows,

SELECTION-SCREEN BEGIN OF BLOCK 1 WITH FRAME TITLE TEXT-001 .

SELECT-OPTIONS: C_CTLPC FOR KNKK-CTLPC. RANGES:R_SBGRP FOR KNKK-SBGRP.

PARAMETERS: C_SBGRP LIKE KNKK-SBGRP,

C_DAY TYPE I OBLIGATORY. SELECTION-SCREEN END OF BLOCK 1.

SELECTION-SCREEN BEGIN OF BLOCK 2 WITH FRAME TITLE TEXT-002 .

SELECT-OPTIONS: O_CTLPC FOR KNKK-CTLPC.

RANGES: R_SBGRP1 FOR KNKK-SBGRP.

PARAMETERS: O_SBGRP LIKE KNKK-SBGRP.

o_DAY TYPE I OBLIGATORY

SELECTION-SCREEN END OF BLOCK 2.

now if i filled the first block.and trying to execute, but it will ask to fill o_DAY also,

now please tell me how to prevent this?

[RichHeilman]

You must not use the OBLIGATORY extension for that field. If you do, it will always give an error when it is not filled.

o_DAY TYPE I OBLIGATORY

Hi rich,

i removed the obligatory extension and now i recodede as follows.

AT SELECTION-SCREEN.

IF CREDIT = 'X' AND C_DAY IS initial.

MESSAGE E002(ZCR).

ENDIF.

IF OVERVIEW = 'X' AND O_CTLPC IS initial.

MESSAGE E003(ZCR).

ENDIF.

IF REVIEW = 'X' AND G_DAY IS initial.

MESSAGE E004(ZCR).

ENDIF.

now its ok but suppose i selected the 2nd radio button and in the 2nd block for the fieldO_CTLPC ,i trying to select multile selection( -> ). in this case also it showing MESSAGE E003(ZCR).

how can prevet this prblm.

regards

hi I have faced similar problem because when u make a field obligatory and if we again use at-selection screen event the error message can not be avoided

Define a form statement which checks whether the field is initial..

try this code, based on the radio button clicked the block appears & disappears, hope this helps

Here's one problem. Shouldn't the ID for the following line be BL1?

SELECT-OPTIONS: C_CTLPC FOR KNKK-CTLPC MODIF ID L1.
