Automated iDPR conversion failed when converting a large data set and while adding new files to the iDPR graphical source. The process started but it didn’t complete, the conversion log showed in the last entry line “Error: Incorrect function”.
The failure was caused by the process handling the iDPR process being out of memory. Loading a large amount of dgn files in a single IDPR conversion job can consume a lot of memory as internally all of those files must be loaded inside a single Microstation process. Very large datasets can be separated into multiple groups. This has the same effect as using multiple input commands with the iDPR converter.
Even when using multiple groups the conversion may face the same problem if the groups are still very large. The solution in this case was to use more groups with a lower number of DGN files, when dividing the data in smaller groups the conversion was completed successfully.
Multiple groups can be created in a Automated iDPR graphical source from the GWP Administration > Data Collection > Graphical Sources > Automated iDPR > Connection Name > Graphical Source Name > General Tab. Click the right arrow button to add a new group and then use the browse button to add input files to the group.
