I am new in aspose library. i want to update the duration (hrs) of assigned resource in the right pan.
based on the calendar by default work duration has been auto assigned. i want to modify its value for each month using API.
is it possible to iterate monthly and set the new value (in hrs) using Aspose API.
Can you please explain the requirements in more details and also in the form of source MPP and desired MPP that you want to generate.
Thanks for your reply mudassir.
I have Source MPP file in which One Task (Task-01.01.001) is already exist. And one resource (Resource1) has been already assign for this task.
Work in hours is assigned daily basis in the right side of the sheet like below for Example:
1st Jan 2ndJan 3rd Jan
8 hrs 8 hrs 8 hrs
Now the requirement is i want to update those works programmatically using aspose library. so the output mpp file contains below :
1st Jan 2ndJan 3rd Jan
6 hrs 7 hrs 5.5 hrs
i don’t want to do any changes in task and resource. only want to update work hours for each date as per the condition in my project.
i’ll browse one Mpp file and after doing above changes i need to save it again.
hope this explanation would be clear to you.

I suggest you to please visit this documentation section link for options related to working with tasks. You may see the examples for changing the task progress as well.
Thanks for the document link.
I had gone through the documents but still my problem has not resolved.
About InputMPP File:
File contain task “Supply Lot Sale Agreement” and one resource named “Builder” has already assign to it.
Now the requirement is to assign two more resource “Client” and “Sales Dept.” to the above task and assign timephased data 20d for june’2008 and 20d for july’2008 month.
And at the same time edit the timephase data of already assigned Resource “Builder” to 15 days and 20 days in June and July month.
Now the problem is for already assign resource “Builder”. Timephased data is not reflecting in the outputMPP file.
i am sharing my code below and attaching the ImputMPP , OutputMPP and ExpectedMPP snap shot.
Awaiting your quick reply.
