Hi Gurus,

How to do automatic field checks (validations) in module pool

one way is by assigning help ( F4 ).

using process on value request (pov)

[Former Member]

your screen then create it in your main program.

You declare the module in the PROCESS ON VALUE-REQUEST.

PROCESS ON VALUE-REQUEST.

FIELD TXT_DOCNO MODULE VALUE_BELNR.

You also need to create an internal table where you wil store results of the select query fired below in the module.

here you will get a F4 help on the filed Document Number(TXT_DOCNO) based on the field Company code (TXT_CODCO)

MODULE VALUE_BELNR INPUT.

progname = sy-repid.

dynnum = sy-dynnr.

CLEAR: field_value, dynpro_values.

field_value-fieldname = 'TXT_CODCO'.

APPEND field_value TO dynpro_values.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'

EXPORTING

tabname = 'BKPF'

fieldname = 'BUKRS'

dynpprog = progname

dynpnr = dynnum

dynprofield = 'TXT_CODCO'.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = progname

dynumb = dynnum

translate_to_upper = 'X'

TABLES

dynpfields = dynpro_values.

READ TABLE dynpro_values INDEX 1 INTO field_value.

SELECT BUKRS BELNR

FROM BKPF

INTO CORRESPONDING FIELDS OF TABLE it_doc1

WHERE BUKRS = field_value-fieldvalue.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'BELNR'

dynpprog = progname

dynpnr = dynnum

dynprofield = 'TXT_BELNR'

value_org = 'S'

TABLES

value_tab = it_doc1.

ENDMODULE. " VALUE_BELNR INPUT
