Hi Corrine,
If you would like to prevent the GTS pop-up messages in R/3 for a block or technical incompletion. Ideal way is to use the BADI that Dave suggested. But instead of completely filtering those documents from being transferred to GTS. You can use a Custom table to hold the user id(batch user or dialog user who loads the transactional data) or the company code/plant as Dave suggests.
Based on this information in the custom table, instead of filtering those documents from transfer- just try to clear the field "CS_CONTROL-LSMES" in the BADI.
This will be a very small change in the BADI. And you will not need to manually transfer those documents later. Loaded documents will be in GTS, but will not give you pop-up messages.
Let me know your thoughts.
Thanks
