Dates not refreshed correctly

Question

Hi,
We are using service contracts BT112H_SC from Web UI. From this component we are calling SAP GUI actions (using transaction launcher) to make changes to the contract u2013 like cancellations, date changes and so on.
We now have a problem with refreshing the Dates assignment block from service contract. The Dates assignment block is handled within a separate component called BTDATES and is called from BT112H_SC using component usage.
When running an action that should change the dates (due to for example an Annulation of contract), the status is set to Cancelled but the dates Contract end date is not changed. I am calling function module CRM_ORDER_READ_OW after the action is executed in some places and see that the dates are updated correctly in the buffer, but they are not showing up in the Web UI.
It seems as the dates are set correctly if I donu2019t expand the assignment block Dates before running the action. So if I expand the assignment block after running the action the dates are set correctly. If expanding the Dates assignment block before running the action, the dates are not updated.
The dates are also set correctly after saving the contract so it is just a matter of visibility.
Also if I (after running the action), go to one of the items and expanding the Dates assignment block on item level and then go back to header level the dates are displayed correctly.
I have enhanced component BTDATES/Dates u2013 Method DO_PREPARE_OUTPUT where I use the following commands that should refresh the values.
me->typed_context->btdate->collection_wrapper->publish_current( ).
    lr_ent ?= me->typed_context->btdate->collection_wrapper->get_current( ).
    lr_ent->reread( ).
I have also used the command modify without success.
Somehow the BTDATES component must be refreshed to read the dates from the buffer correctly after the action is executed.
Do anyone have any suggestions on how to handle this?

Hi,
Thanks a lot for your answers. I need all input I can get.
Kathirvel: I can see that event 0002_expand_link is triggered (from class  ZL_BT112H_S_MAINWINDOW_IMPL I believe) when expanding the Dates assigment block. But I cannot figure out what is happening next.
But after expanding the assignment block once, the event is not triggered if I expand/collapse the assigment block again.
I see that in CL_BSP_WD_VIEW_MANAGER ~ DO_FINISH_INPUT when expanding Date assignment block, a BOL_CORE->MODIFY statement is made. This code is triggered when expanding the Date assignment block (but only first time).
Do you know which event I could call to trigger the update again?
asen2222 : I entered the code lr_core->modify( ) in ZL_BT112H_S_OVVIEWSET_IMPL ~ DO_PREPARE_OUTPUT which is called after my action is executed and the dates are modified in the buffer. But it doesn't work. When debugging the modify( ) method it seems as it have no delta-information to save.
I have also tried setting the statement in component BTDATES - ZL_BTDATES_DATES0_IMPL ~ DO_PREPARE_OUTPUT without success.
In the same place -  component BTDATES - ZL_BTDATES_DATES0_IMPL ~ DO_PREPARE_OUTPUT  -  I also put the following code:
lr_ent ?= me->typed_context->btdate->collection_wrapper->get_current( ).lr_ent->reread( ).
This do not work either. But if I debug the reread method and go into
method REREAD_ENTITY of CL_CRM_BOL_CORE I see following code:
lv_relation_cacheable = me->object_model->relation_is_cacheable(
lv_parent_relation_name ).
If I then set lv_relation_cacheable = ' ', it seems to bypass the buffer and read the data from underlying layers. And then the values is showingcorrectly updated!.
I believe it is reading the relation from table CRMC_ORLSTA_BTIL but this
table do not include field DO_NOT_BUFFER so I assume this field should
never be set for business transactions. But in this case it wouldhave worked for us.
