F4 Search Help

Former Member — Tue, 15 Apr 2008 12:04:25 GMT

Hi Gurus,

In am facing a big prob...

In my selection screen i have 2 input fields,

say, field1 and field2.. Both field1 and field2 has F4 Search helps..My requirement is, if i select field1 from F4 Search field2 also shud populate based on the selection of field1.

Say when i selected field1 search help values populated are

field1 field2

a 1

b 2

a 5

a 6 etc......

Now if i select a - 5 using field1 search help...field2 has to be populated with 5 along with field1 ....

So after selecting 'a' fields shud look like this...

field1 - a

field2 - 5

Any way in which i can acheive this...

Full rewards for appropriate answers...

Regards,

Hi,

You need to use At selections screen output event.

Under this you need to code for pupolating your own search help depending on certain values from first field.

There is one FM for this.... you need to check for it.... do F4help* and you should get that FM.

Or you might also find some similar codes here on SDN itself

search by F4 help for custom fields.

Hope it helps.

Hi,

Check the below code.

PARAMETERS: P_MNR TYPE FCMNR,

P_LTX TYPE FCLTX.

DATA: BEGIN OF ITAB OCCURS 0,

MNR TYPE FCMNR,

LTX TYPE FCLTX,

END OF ITAB.

DATA: RETURN TYPE TABLE OF DDSHRETVAL WITH HEADER LINE.

INITIALIZATION.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

READ TABLE RETURN WITH KEY FIELDNAME = 'P_MNR'.

Add it back to the dynpro.

Hi,

See my requirement is different i think from ur code..which is using DYNP_VALUES_UPDATE not work here...Yes i have to use this definitely to update the second field..but for this i have to get the corresponding data in 2nd field..i will xplain it

Bharat / Velangini,

Ur sample code is different from my requirement...in ur code F4 Help is for plant code and u have to fill plant name accordingly....so this is an easy job since for a plant code thr will be only one plant name..just like one phone no will only belong to one particular person so identification is easy....please correct me if i am wrong...

but my requirement is

one material say M1 can belong to say 7 plants..if user selects from f4

M1 and 3rd plant i shud get tht coresponding plant also...i am using this FM

'F4IF_INT_TABLE_VALUE_REQUEST' here as tables parameter i am passing both material and plant...but since export parameter only has material info like DYNNR, Field name etc..in RETURN_TAB i am only getting M1 from it...

Also,,,

Hi Gangi reddy,

I think u r refering to table level search help rite....table level we can set the export and import parameters for the fields...wherein u select one material and plant for material search help values will automatically populate rite..But sorry i cant go as of now table level...i know tht will work out..but i need know any FM is thr wherein we can get both from one.....

Rewards will be done for appropriate answers.....
