Selection- Screen

[Former Member]

Is there any way to find out in the selection screen, if all the fields are blank, other than checking for all the parameters?

PS. Deserving answers will be given maximum points.

HO Bharath,

NO other way. you have to check if each and evert parameter is filled or not.

at selection-screen.

if P_field1 is initial and p_field2 is initial and p_field3 is initial.

message e001 with 'all parameters are empty'.

endif.

There is no such statement or utility that gives us the information. Here we are talking about the fields of selection screen and each of them is to be checked to be not initial.

Sorry no way, in selection-screens there are no equivalent for ON INPUT and ON CHAIN-INPUT thart exist on standard Dynpro.

You will have to check each parameter or select-options, or build a super-structure with all parameters and select-options included and check it.

Hey bali,

use fm ' to check the selection screen values. DYNP_VALUES_READ' This function module reads screen field contents that are to be processed by the help modules.

U could have asked this to me by giving a call instead of knowing the answer here. now dont call.

Mark all helpful answers.

loop at screen.

......

endloop.

if you want to know the details , please read the help on the sap help dodument.

chk this FM REUT_CHECK_SELSCREEN_INPUT'

[Former Member]

Call the function modele like below:

To have all the field names and values in an internal table .

Then

loop at this internal table

check if is initial is TRUE

if atleast one is not initial make w_flag =1.

endloop.

if w_flag = 1.

all fields are not initial

else

all fields are initail.

endif.
