F4 - Help

[Former Member]

Hi ,

I have two fields in Selection screen.

Entry is made in first field of selection screen, Based on the entry in the

first field , the second field should have f4 help which brings the value from

table based on the first field entry.

How to do this.Help me to solve thid issue.

Thanks.

In these type of situations it is better to choose a drop down facility in the second input field based on the condition of the first field.

It is possible in MPP using Type pools VRM and the internal table VRM_SET_VALUES.

Cheers.

Hi,

Look at the SAP DEMO program <b>DEMO_SELECTION_SCREEN_F4</b>

Also, the below are the F4 help examples for Dailog Screens

Hi,

You can use following method.

Here firstly populate the all the data regarding first field into local internal table

Let us assme first field is plant and second is material.Then first populate the

all the materials regarding plant which is given on the selection screeen into one local internal table.then use following field.

Itab contains two fields plant and material

AT SELECTION-SCREEN ON VALUE-REQUEST FOR field2.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

You'll need to dynamically read the value for the field you are depending on, then you could build your F4 help using that value. Say for example we have a select option s_pernr-low that depends on the value input for s_kunnr-low.

In order to read the value:

-

---

at selection-screen on value-request for s_pernr-low.

DATA: BEGIN OF DYNPFIELDS OCCURS 1.

INCLUDE STRUCTURE DYNPREAD.

DATA: END OF DYNPFIELDS.

CLEAR DYNPFIELDS.

REFRESH DYNPFIELDS.

DYNPFIELDS-FIELDNAME = 'S_KUNNR-LOW'.

APPEND DYNPFIELDS.

• DYNPFIELDS table will hold your field name and the value.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-REPID

DYNUMB = SY-DYNNR

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = DYNPFIELDS

OTHERS = 11.
