F4 help in module pool programming

[Former Member]

Hi Experts,

I have two issues in module pool programming.

1) In my screen 100, I have 3 fields matnr(Material number) and sernr(Serial number) and TestID (Custom value)

I have a table DDIC standard 'Z' with the above fields MATNR,SERNR,TESTID and DATE.

I have created a simple F4 search help to TESTID and have assigned to the parameter in module pool.

My question is I want capture the matnr entered in the screen 100 and automatically assign it to the F4 help screen that pops up automatically when I hit F4 button. While creating the search I help I gave the search parameters as matnr,sernr and date. My issue is I must pass the value entered in the screen 100 to the search help screen automatically.

2) I have created a custom domain location 'ZLOCATION' in its value pair, I have maintained the value for the domain.

(E.G) V - Vendor, O - Other etc. In my module pool, I have one of the fields type as ZLOCATION. And once I press F4 help for this parameter, the value maintained should appear.

3) Is it possible to provide text box(for comments) in module pool programming?. Text box - having multiple rows for input instead of one row.

Awaiting reply experts thanks.

For your 1st query,

make use of FM DYNP_VALUES_READ to read the user entered value in the screen. You should write this business logic inside the search help module for that field written under PROCESS ON VALUE-REQUEST.

Eg:

dynpfld-fieldname = 'MATNR'. (Name of the field in the screeen)

append dynpfld.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = sy-repid

DYNUMB = sy-dynnr

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = dynpfld.

read table dynpfld INDEX 1.

matnr = dynpfld-fieldvalue.
