Hello,
I think I may have the answer, but I will still ask the question. My co-worker has imported a file (.xer) into his master project. There is one activity showing that it has a constraint, but has none. Is this perhaps a bug in the program? Even on the schedule log report that particular activity comes up as having a constraint. I had him send me the file and I ran the log report and it did not show as a constraint, but in the shedule itself again showed as a constraint. Is this possible that he imported a different ver of p6 that was not compatible. This is a total mystery, can you help me solve this issue? Have to know.
Hello Anna,
for me the best way to import a .XER-File is the following:
This is for me the easiest way to clean up XER-Files and prevent errors in Primavera.

Hi Anna
When I had the same problem the cause was a link from some imported activities to successors/predecessors from another project.
Primavera when exporting a project replaces these relations by a date (early start or finish date of predecessors/successors) placed in the external constraint field. These external constraints do not appear in the activity form and you have to call them as collumns.... Hope it helps

Not sure about P6 but MS project can have a global constraint on the overall project completion which could be an issue.
I do not use P6 but for what I have read at PP it occurs to me it can be [a substitute to] an external link or link to another project.
Best regards,
