Table control validation

Former Member — Wed, 05 Oct 2011 08:25:46 GMT

Hi Experts,

I have 4 fields in table control. 1. Material 2. Description. 3. Unit of Measure 4. Quantity.

I have to first validate material, than if material is exits, i am populating data to description and unit of measure field.

once i populate the data to the field description and unit of measure, i want to validate quantity.

if user not entered quantity, i have to raise the message. pls enter quantity.

i have following code

loop at it_matnr.

chain.

field it_matnr-matnr.

field it_matnr-maktx.

field it_matnr-meins.

field it_matnr-bdmng.

module check_matnr on chain-input .

module tc_matnr_modify on chain-request.

module check_bdmng on chain-input.

endchain.

&----

*& Form check_matnr

&----

text

----

-->P_IT_MATNR_MATNR text

----

FORM check_matnr USING P_MATNR TYPE matnr.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

INPUT = p_matnr

IMPORTING

OUTPUT = p_matnr

SELECT SINGLE matnr into v_matnr from mara

WHERE matnr = p_matnr.

if sy-subrc ne 0.

MESSAGE e999 WITH 'material' p_matnr 'does not exist'.

endif.

ENDFORM. " check_matnr

&----

*& Module check_bdmng INPUT

&----

text

----

MODULE check_bdmng INPUT.

if it_matnr-bdmng is initial.

MESSAGE e999 WITH 'Please enter Quantity'.

endif.

ENDMODULE. " check_bdmng INPUT

MODULE tc_matnr_modify INPUT.

DATA: lv_matnr TYPE matnr.

IF it_matnr-matnr IS NOT INITIAL.

CLEAR lv_matnr.

CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT'

EXPORTING

input = it_matnr-matnr

IMPORTING

output = lv_matnr

EXCEPTIONS

length_error = 1

OTHERS = 2.

SELECT SINGLE maktx FROM makt INTO it_matnr-maktx

WHERE matnr = lv_matnr

AND spras = sy-langu.

IF it_matnr-meins IS INITIAL.

SELECT SINGLE meins FROM mara INTO it_matnr-meins

WHERE matnr = lv_matnr.

CALL FUNCTION 'CONVERSION_EXIT_CUNIT_OUTPUT'

EXPORTING

input = it_matnr-meins

language = sy-langu

IMPORTING

LONG_TEXT =

output = it_matnr-meins

SHORT_TEXT =

EXCEPTIONS

unit_not_found = 1

OTHERS = 2.

ENDIF.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'

EXPORTING

INPUT = it_matnr-matnr

IMPORTING

OUTPUT = it_matnr-matnr

MODIFY it_matnr

INDEX tc_matnr-current_line.

IF sy-subrc NE 0.

APPEND it_matnr.

ENDIF.

But i am facing the problem, once i validate material, it will fill 2 fields, but it is not going to quantity validation.

Please let me know what i have to change.

field it_matnr-meins.
field it_matnr-bdmng.  " Comment this here

field it_matnr_bdmng module check_bdmng. "As a sepaate check or try using ON INPUT or ON REQUEST

Hi,

Remove chain-input from -

module check_bdmng on chain-input.

chain-input is triggered when u input value and Request is triggered when ever u change value in field .
