CHAIN END CHAIN IN MODULE POOL

Hi gURUS,

i have 4 columns in table control

matnr , quantity, meins , plant.

i enter the values for

material , quantity , meins and plant in table control and hit enter.

My code is like this.

FIELD Itab-MATNR module testm_matnr.

FIELD Itab-quan.

FIELD Itab-meins.

FIELD Itab-werks MODULE testK_werks.

in module testm_matnr i have the following code.

data : testm like mara-matnr.

select single matnr in testm from mara

where matnr = itab-matnr .

if testm is initial.

mESSAGE E999 WITH Itab-MATNR 'Material Doesnot exist'.

endif.

in module testk_werks i have the following code.

data : test like marc-matnr.

select single matnr in test from marc

where matnr = itab-matnr

and marc = itab-marc.

if test is initial.

mESSAGE E999 WITH Itab-MATNR 'Material Doesnot belon to plant'

itab-marc.

endif.

My question is,

1) I have entered all the four values , if the material is wrong then

i can input only matnr since i don't chain and chain.

let says i have entered a correct material but the PLANT is wrong.

Now the plant is available for input.

But NOW IF I DECIDE TO CHANGE THE MATERIAL INSTEAD OF PLANT I CANNOT BECAUSE I AM ABLE TO INPUT ONLY THE PLANT FIELD.

SO I HAD THE CHAIN AND ENDCHAIN

CHAIN.

FIELD Itab-MATNR module testm_matnr.

FIELD Itab-quan.

FIELD Itab-meins.

FIELD Itab-werks MODULE testK_werks.

ENDCHAIN.

I entered all the values and hit enter

NOW THE ISSUE IS WHEN MY MATERIAL IS WRONG I DON'T SEE ANY VALUES FOR

QUAN , MEINS , WERKS.

My requirement is

I input all values when some thing is wrong i should be able to change whichever field i want and at the same i need to retain the previous values.

I SHOULD BE ABLE TO TO INPUT ALL FIELDS AND AT THE SAME TIME I SHOULD BE ABLE TO RETAIN THE VALUES OF OTHER FIELD AS WELL.

I TRIED THIS WAY BUT IT DIDNOT WORKED FOR ME.

CHAIN.

FIELD Itab-quan.

FIELD Itab-meins.

FIELD Itab-werks.

Not sure why you are not able to see previous values, but try coding like this.

CHAIN.
   FIELD: Itab-MATNR , Itab-quan,
          Itab-meins,  itab-werks.
   MODULE TEST_ALL_FIELDS.
ENDCHAIN

.

Code a new MODULE which will check all of the fields in sequence.
