Retaining value of a variable .

[Former Member]

Hi All,

I am trying to enable disable the controls on selection screen depending upon the value of a variable. The value of the variable is getting set in the program.

The program calls a transaction , now when i press the back button from that transaction , i want to show different controls on the selection screen and want to disable the previous controls.

I tried to save the value of the variable to the ABAP memory but its not working .

Please Suggest wht can be done to solve the problem.

Hi,

try to assign the value of the variable

in the at selection screen output..

for ex

initially some X wil be shown in the selection screen..

after executing the program

you are calling a transaction

and take the value from the transaction

by using

get parameter

and pass this value in the at selection screen output..

hope this works,

this is just a suggestion ....

HI Venkatesh,

Thanks for ur suggestion.

I would like to add something to my question. The variable's value is not getting set in the transaction , i am just setting it 1 by assigning value 1 to the variable n when next time the program loads after clicking on back ,i am checking the value of this variable if it is 1 then i am enabling some different controls. But when program loads again the variable value is again getting set to 0 , so i want to retain this value.

Tell if any method is there for this.

Thanks

Hope you are using IMPORT AND EXPORT

EXPORT <variable> TO MEMORY ID 'TD'.

IMPORT <variable> FROM MEMORY ID 'TD'.

Hi,

Use the DATABASE option in the EXPORT / IMPORT statement..to retain the value..

Ex..

EXPORT v_value TO DATABASE indx(ST) ID 'ZMY_VALUE'.

IMPORT v_value FROM DATABASE indx(ST) ID 'ZMY_VALUE'.

Thanks,
