hie, I am working on a module pool program where i have a table control and i need to get VBELN through a input field and based on that field i need to write a select query and display the so items in table control.

i have defined the input field as vbak-vbeln for the input field in the screen, activated it.

the prob is ,When i write the select query, i get an error that vbak-vbeln is not defined.

can any one tel me what could be wrong ?

That name is accessible only in your screen & not in your program. You have to either use tables statement ( obsolete) in your program like tables:VBAK , or declare a individual variable referring to vbeln and use that variable name to your screen field.

if that is the problem, previously had a report program where the input field declared in the screen was accessible in the program. I did not declare an individual variable for that ... same here, but a module pool.. and this not working

Additional Information: During the debugging mode, the input field which i declared on the screen is accessible in program holding the VBELN, but when i give the same in the program, it throws an error

Report program & module pool both are different.

"During the debugging mode, the input field which i declared on the screen is accessible in program holding the VBELN - Which Program ?, but when i give the same in the program, it throws an error" Which Program. ?

Hope you understood what i meant.

Dear Karthikeyan,

In the include top declare as below:

data:vbak type vbak.

Vbak will be structure now and when you have defined the input/output fieldname as VBAK-VBELN ( Note: while defining in the input/output field you need to call the variable from program not from dictionary ) then that value will come to the structure field VBAK-VBELN which can be used in your select query.

With thanks & regards,

Thank you for all your valuble comments. I solved the problem myself.. The mistake i did was i used program fields window(F6) in the screen and displayed the input field directly from the DB table. So the Input fields acts as a two way both for Saving and displaying.

It will be a confusion there SO what i did was i declared a local varaible refering to vbeln and i used program fields window, insted of getting from attributes, i clicked on Get from program.I linked that local variable to the input field .. Problem solved.
