How to refresh task hierarchy after creating some tasks programmatically?

[jj1]

Hi,

How can I get the left task hierarchy (or tree) get refreshed with new tasks which are created by myself programmatically in cPro 4.5?

I created some tasks under the exising task but they are not shown in the left task hierarchy automatically, only shown after I refresh the page manually or by re-entering the project again.

Thanks in advance for your help. Any suggestion would be helpful.

Best regards,

Beiyang

Hi Beiyang,

If you are using xRPM portal and cProjects within that, please consider the option of refreshing the cache memory.

If you are connected to cProjects directly without xRPM, you can always close that project. Go to another tab and then open that project again. I believe it works.

Please let me know if it solves your query.

Hi Nishit,

First thank you for the suggestion here. Is there any sample code for that?

I am a newbie for cPro, don't know how I could do to get the cache refreshed programmatically or close/open the project by code.

I am trying to find some sample code to refresh the task hierarchy programmatically, currently I am checking on CL_DPR_PROJECT and CL_DPR_TASK but don't know whether this is the correct direction.

Thanks and regards,

Beiyang

Hi Beiyang,

If you are using cProjects in xRPM Portal, then go to Portfolio Management > Administration > Cache Administration > Invalidate selected Cache..

By doing so, it refreshes the cache and the real time data is getting displayed. But this is manual mode.

Code below notifies the dpr_tree webdynpro component of the creation of a task.

The dpr_tree component will receive the changes and upate itself in its on_update method.

(Please be aware that the parents of the newly created task to the root node should already be loaded in the tree)

The important method is lr_api_chg_hndlr->NOTIFY_CREATE(

  data lv_objtype type cgpl_object_type.
  data lr_chg_mgr type ref to cl_dpr_ui_change_manager.
