Material is spent on …

I agree with Rafael, this is confuse me too. I try two variations this schedule, first makes activity 3 SS(start-start) with activity 2, but the dialog says same thing:

Second Option, how activity 3 depends on from activity 2, I changed for activity 2 be supplier and activity 3 be consumer, and the dialog anymore shows. Maybe algorithym consider that the supplier must comming first than consumer? like figure bellow!

I recreated the example. It is a bit confusing I admit, but in the Reason of delay for activity 2 Spider fills in „Material "Material A" (Code: A); 0 days”.

So you could filter for this.

It would be great if in the schedule report you would get similar to resources...Activity 2 (Code:2) is delayed due to Material A (Code:A) which is spent on xx.yy.zzzz hh:mm

Maybe in the Material Gantt a vertical red line could be drawn in order to highlight material supply constraints (this is implemented in the Resource Gantt).

Spider Project reports that on certain date it cannot start the next activity because available materials are not sufficient for its execution untill the end.

If consumption preceeds the supply then consumption activity cannot start and Spider Project reports that on certain date material availability is not sufficient for scheduling of remaining activities.

It is not that by 04-02-21 all Material B is spent, by this date no Material B is spent and all of the supply by Activity 1 (-500) is still available.

• Perhaps it should read - On 04-02-21 Material A availability is not sufficient for scheduling of remaining activities.

I guess the solution to this issue is on the scheduler not on the software; can be solved by increasing supply before this date, can be solved by decreasing consumption after, or by a combination.

Yes,

"Material A availability is not sufficient for scheduling of remaining activities" is the right wording.

Thank you!

But what is the date that matters?

Materials Gantt helps keep focused.

In my example total supply was increased but there is an excess of 2000 units that should be solved. In this case figuring out the date is easy but what about more complex scenarios?

• Is it good idea to display a date?
