Unable to perform validation properly

[Former Member]

Hi All,

Please help me out. I am having a scenario in a dialog prog where i have a screen in which a table control is there.1st coloum is a check box (screen name is WA_MARA-ZZSELECT), 2nd coloum is MATNR where a F4 help is used for Input.As the Input is given using F4 help, value of corresponding MATKL should come in coloum 3.

For validation one needs to select a record/records by marking the check box and click on a push button- CHECK.

Now i need to validate the input as follows:

1) if a user doesnt select any record and clicks on CHECK, he should get a msg saying "Select a record first".

2) If a user doesnt give any input and select a record and click CHECK, he should get a msg saying "enter value using F4."

3)If a user enters two same MATNR as input by F4 and then select any one of the records and click on CHECK he should get a msg- "Entry repeated".

4) If none of the above happens then he should get a msg - "Proper Data".

The code i have developed (though not working perfectly) is:

• For Validation

CASE OK_CODE.

WHEN 'CHECK'.

IF WA_MARA-ZZSELECT = ' '.

MESSAGE E008. "Select a record first

ENDIF.

IF WA_MARA-ZZSELECT = 'X'.

IF WA_MARA-MATNR IS INITIAL.

MESSAGE E006. "Enter value using F4

ELSE.

READ TABLE I_MARA INTO WA_MARA WITH KEY WA_MARA-MATNR.

IF SY-SUBRC = 0.

MESSAGE E005. " Entry repeated

ELSE.

MESSAGE E009. " Proper data

ENDIF.

ENDIF.

ENDIF.

ENDCASE.

Please guys help me with the correct logic.

Hi,

Try using this way:-

MODULE validate_data.
  CASE sy-ucomm.
    WHEN 'CHECK'.
      IF WA_MARA-ZZSELECT = ' '.
        MESSAGE E008. "Select a record
      ENDIF.

      IF WA_MARA-ZZSELECT = 'X'.
        IF WA_MARA-MATNR IS INITIAL.
          MESSAGE E006. "enter value using F4 
        ENDIF.
      ELSE.
        "take another internal table it_temp and same as it_mara
         it_temp = it_mara.
         SORT it_temp BY matnr.
         DELETE ADJACENT DUPLICATES FROM it_temp COMPARING matnr.
         IF sy-subrc = 0.
           MESSAGE E005. " entry repeated 
         ELSE.
           MESSAGE E009. " proper data
         ENDIF.
      ENDIF.
  ENDCASE.
ENDMODULE.

Hope this helps you.

Hi Tarun,

I have tried implementing your code.

The problem i am facing is whatever selection i make, irrespective of that i get one fixed message - SELECT A RECORD.

I tried to debug the code..Even if i give two similar inputs and then select one the records and click on CHECK, then also i am having the same message- SELECT A RECORD.

I would appreciate your help.

Hi,

Use:-

PROCESS AFTER INPUT.
*  MODULE user_coomand_8001.

  LOOP WITH CONTROL tab_ctrl.
    MODULE modify_data.
  ENDLOOP.

  MODULE validate_data.

In PAI,

MODULE modify_data.
  MODIFY it_mara FROM wa_mara INDEX tab_ctrl-current_line.
  "modify the contents into internal table from table control
ENDMODULE.

MODULE validate_data.
  CASE sy-ucomm.
    WHEN 'CHECK'.
      REFRESH it_temp.
      REFRESH it_temp1.
      CLEAR it_temp.
      CLEAR it_temp1.
     "take another internal table it_temp and same as it_mara
      it_temp = it_mara.
      READ TABLE it_temp INTO wa_temp WITH KEY zzselect = 'X'.

      IF sy-subrc ne 0.
        MESSAGE E008. "Select a record

      ELSE.
        IF WA_MARA-MATNR IS INITIAL.
          MESSAGE E006. "enter value using F4 
        ELSE.
          "take another internal table it_temp1 and same as it_mara
          it_temp1 = it_mara.
          DELETE it_temp1 WHERE matnr = wa_temp-matnr.
          IF sy-subrc = 0.
            IF sy-dbcnt > 1.
              MESSAGE E005. " entry repeated 
            ELSEIF sy-dbcnt = 1.
              MESSAGE E009. " proper data
            ENDIF.
          ENDIF.
      ENDIF.
  ENDCASE.
ENDMODULE.

Hope this helps you.

HI ,

1. First Check for the Record is selected or not

2. Checkl for the matnr entered or not by checking for initial values.

3. If value is entered is repeated or not .

4. if every this is ok continue your process.

Copy the Old data to one internal table in PBO to check for the dulpicate entries

IF WA_MARA-ZZSELECT = 'X'.
  IF WA_MARA-MATNR IS INITIAL.
      MESSAGE E006. "Enter value using F4 
 ELSE.
     READ TABLE I_MARA_OLD INTO WA_MARA1 WITH KEY MATNR = WA_MARA-MATNR.
     IF SY-SUBRC = 0.
        MESSAGE E005. " Entry repeated 
      ELSE.
         APPEND WA_MARA1 TO I_MARA.
         MESSAGE S009. " Proper data
      ENDIF.
 ENDIF.
ELSE.
   MESSAGE E008. "Select a record first
ENDIF.

HI,

Check wether you flag for the selected record is getting populated or not.
