Call Transaction in Background for IW52

Hi All..

When i execute my BDC (Call Transaction) in foreground, the code will update IW52 screens without any errors/warnings.

But if we schedule this in background, the IW52 screens are not getting updated.

Even there are no Errors observed.

We have used the syntax as follows..

CALL Transaction IW52 using it_bdcdata MODE 'N' messages into it_bdcmsg.

Can anyone help me how to rectify it and make it to execute successfully in background mode..??

Your Help will be highly appreciated..

Regards

Pavan
