BDC & exit from tranction

Hi,

I am using BDC to start transaction MM01. I am only using BDC to skip the first initial screens, in which you need to enter the material number & type, views and plant/storage location data, etc. Then the user must fill the rest of the data manually.

Now the problem is that if I want to exit the transaction (without filling the data), it is not possible. Only the green "back" button is enabled, and I cannot use that to exit the transaction, since there are mandatory fields missing, and I am getting errors due to the missing mandatory fields.

If I launch the transaction directly, also the yellow exit button is available, and I can exit the transaction without filling the mandatory fields.

Is there any trick to avoid this problem? Or should I just forget the whole BDC thing?

Regards,

Pa
