[VUE 3] inconsistency in start and end dates

[cospino]

Hi,

I’ve been running some tests importing Microsoft Project files in the Bryntum web page:

https://bryntum.com/products/gantt/examples/msprojectimport/

The import is done successfully, but checking in detail all imported data, we find some inconsistencies in the dates. You can see an example in the attachment.

The attachment clearly shows that Row 137 in the Microsoft Project file there’s an activity named “Desmonte linea de eje”, and this activity begins on Friday, April 26th and ends on Tuesday, April 30th. Nevertheless, Bryntum Gantt’s reflects different dates in the same activity (“Desmonte linea de eje”) and shows beginning on April 29th and ending on May 2nd. We have checked many times and haven’t found yet a concrete answer about why this is happening.

Please help us on this problem, to find a solution promptly. Many thanks in advance.

Hi

Can someone help me with this?

Hello,

The task on row 137 is shifted to Apr 29, because it has an incoming dependency from the previous task on row 136.

This is an unfortunate difference between the MSProject and Bryntum scheduling - the MSProject does not account for incoming dependencies, if task has percent done > 0 and we do not have such special processing.

We already have ticket for this issue: https://github.com/bryntum/support/issues/6766 I'll notify the team regarding possible prioritization.

there is an estimated date for the solution of this problem?

we need this functionality to go into production

We'll try to prioritize it, can't provide estimates though.

@cospino At the moment, we can prioritize the simplified solution for this issue, which will just prevent a task from being affected by its predecessors when it has percentDone > 0. Would it be enough for your needs?

The full solution with task split, as described here described here would require certain effort and would be delayed.

Hi,
I see that this ticket has already been resolved since version 6.0.2 but the problem persists. When importing the file (Bryntum Example.mpp) that I attached at the beginning of this ticket, the start and end dates of the project do't match.

It seems that you are not taking into account the project calendar, in Bryntum Gantt it assumes that April 4th to April 21st are 46 days, this is not correct.

Please help us with this ticket, we need to go into production and this error prevents it.

Hello,

That ticket issue was resolved but we didn't check if your file is handled correctly.
And it looks there is more than one issue when handling the file.
Here is one more ticket for the case: https://github.com/bryntum/support/issues/9977

Sorry for the inconvenience and thank you for the report.

Best regards,
Arcady

thanks Arcady, when will version 6.0.6 be available?

Hey cospino1,

Most likely 6.0.6 will be released in the next one or two weeks.
