ZTC_ATMP-LEGACCNO,

ZTC_ATMP-ZZDESKCODE,

ZTC_ATMP-SAKNR.

MODULE READ_TABLE_CONTROL.

MODULE check_duplicates ON CHAIN-REQUEST.

ENDCHAIN.

ENDLOOP.

Hi there.

Two questions:

1 - is that code in PAI of table control screen?

2 - go to screen layout (graphical) and check in the lines of table control if the fields are really named ZTC_ATMP-BUKRS, etc ...

Best regards.

Hi,

you can try like this...

************************************

LOOP AT IT_TC2.

CHAIN.

FIELD ZTC_ATMP-BUKRS module CHK1.

FIELD ZTC_ATMP-LEGACCNO module CHK1.

FIELD ZTC_ATMP-ZZDESKCODE module CHK1.

FIELD ZTC_ATMP-SAKNR module CHK1.

MODULE READ_TABLE_CONTROL.

ENDCHAIN.

ENDLOOP.

Now write the validations for the corresopnding Fields in there Respective Modules.... for example Validation for ZTC_ATMP-BUKRS filed in module CHK1 and so on..
