At selection-screen on value-request, at selection-screen on

[former_member125661]

I have 2 selection-screen options :

s_region and

s_state .

Here Region would mean North,South,East,West

I have At selection-screen on value request for both of these selection options.

But when I click F4 for s_state, I want to capture the selection made by user on s_region so that I only query for states under region. For eg: if South was chosen, I only want to bring up states in South Region.

I have both at selection-screen on and at selection-screen on value-request. But when I type South for s_region and press F4 for s_state, the internal table s_region[] is not filled in 'At selection-screen on value request for s_state-low . This is because at selection-screen on value-request is called before at selection-screen on - event. Only at selection-screen on s_region populates s_region.

How would I get around it ? I want to access entries in s_region during on selection-screen on value request for s_state, (without me having to hit enter key after first selection).

Shareen,

The best option would be to use 'DYNP_VALUES_READ' FM.

For eg: You've S_Region and S_state as two Selection-option fields.

After user selecting the Region, when click F4 in S_state, use this.

Data: I_SCR_FIELDS LIKE DYNPREAD OCCURS 0 WITH HEADER LINE.

At selection-screen on value-request for s_state-low.

Perform: Get_state.

At selection-screen on value-request for s_state-high.

Perform: Get_state.

FORM GET_STATE .

move 'S_REGION-LOW' to I_SCR_FIELDS-fieldname.

append I_SCR_FIELDS.

move 'S_REGION-HIGH' to I_SCR_FIELDS-fieldname.

append I_SCR_FIELDS.

*--- Get the screen values

call function 'DYNP_VALUES_READ'

exporting

dyname = Sy-cprog

dynumb = Sy-dynnr

tables

dynpfields = I_SCR_FIELDS

exceptions

invalid_abapworkarea = 04

invalid_dynprofield = 08

invalid_dynproname = 12

invalid_dynpronummer = 16

invalid_request = 20

no_fielddescription = 24

undefind_error = 28.

*

*----Read the return value-

Read table I_SCR_FIELDS index 1.

*----Or you can read table I_SCR_FIELDS with the key, depends on your req.

I_SCR_FIELDS-FIELDVALUE will have the value for the region.

Once you have the Region value, you can build the logic to get the relevant states.

ENDFORM. " GET_STATE

Hope this helps.
