Hi,

Have you used in a LOOP.

Ex:

LOOP AT SCREEN.

screen-name = 'checking'.

ENDLOOP.

Hi meriem,

My guess is you have put the Loop at Screen logic in a place which is not supported.

If you are using module pool Screen should be used only inside the PBO module and if you are using report program then it should be used inside At selection-screen output event. The SCREEN data object would be only available inside these events.

Please check table control structure ,may be problem in structure definition.

Thanks.

Hi,

Where in the code you are using screen-name???

Re: error in table control

Former Member — Thu, 23 May 2013 10:41:31 GMT

i had resolve the problem.

i used a variable called screen in my program.

so i rename it.

Re: error in table control

RaymondGiuseppi — Thu, 23 May 2013 11:40:18 GMT

Can you post the code of MYALV_CHANGE_FIELD_ATTR module.

ALV list/grid and Table Control are two different tools, giving the name MYALV to a TC should not be done in real life, It will only confuse developers who would later maintain the program.
