ISU_S_WORKLIST_INSTALL-Creating move in reads

Hi,

We are processing and IDOC and calling ISU_S_WORKLIST_INSTALL FM to install a device to an installation.

If the installation is just moved in and does not have a move-in read this FM internally calls 'ISU_ADD_MISSING_MOVEIN_EABLS' to create a move-in read.

Is there any way to make sure this 06 read does not get created automatically?

Thanks.

Joshua.
