Saving SCD to database fails with 0102

[JakobVogelsang]

Subject of the issue
When I want to save an SCD file to the database, I get an error with error code (0102) and the file is not saved to the database.

Steps to reproduce
Open any SCL. Go to save as and try to save as an SCD file.

We think that the issue is caused by large SCL files in the SCD section of the database. When opening those to check for name uniqueness is potentially causing a timeout.

It looks like the connection to the database has a timeout. When trying to save, the logging says that there is no open transaction

On the backendside it is probably fixed, it needs a front-end modification.

It is still an issue?
