Outbound INVOIC01 e1edkt1 and e1edkt2 not working

Hi,

in outbound idoc Invoic01, we are populating header text which is present invoice header text, but adding additional texts from SO10 text,

problem is when idoc is getting triggered using Send immediately option, e1edkt1 is partially filled and no e1edkt2 is populated, but if i run this scheduled job instead of send immediately, its working fine.

not sure why its not working for Send immediately option.

appreciate your help guys..

Thanks,

Unni
