User- Control Framework: Fatal error - GUI cannot be reached

[Former Member]

Hi,

I am currently working on a Project , were I am facing an issue.

I have Inbound IDoc which come, runs a BDC and then Packs HU via transaction VT02N.

The Problem is when I or some user manually trigger this IDoc via WE19 the code works fine,

But when an external system sends an IDoc we have system user which does the processing and while doing so it gives out an message "User- Control Framework: Fatal error - GUI cannot be re", we cannot debug this. I managed to capture all system message and save them in a file.

Could some one kindly help me with this.

It seems that you are calling a dynpro during background processing. In background however, dynpros can not be processed. Are you using CALL TRANSACTION with BDC_OPTIONS to display the screens (MODE A, E for example)?

hi.

you are correct , we have used call transaction in N mode,

But initially it used to work and suddenly its behaving like this.
