What is the IDR?
The IDR, found in the header area of OIF and GAF floorplans, is to display information in label/value pairs that are relevant to the data processed in the application.
This blog describes how the content of label/value pairs can be changed at runtime via ABAP APIs.
Step-by-step: Changing the values
You can access the IDR API using the following code:
DATA: LO_IDR TYPE REF TO IF_FPM_IDR.
DATA: LO_FPM TYPE REF TO IF_FPM.
LO_FPM = CL_FPM=> GET_INSTANCE( ).
LO_IDR = LO_FPM-> GET_SERVICE( IF_FPM_CONSTANTS=>IDR ).
Now that you have the API for the IDR, you can use it in the following way:
DATA: LT_ITEM_GROUP_KEYS TYPE T_ITEM_GROUP_KEYS.
LT_ITEM_GROUP_KEYS = LO_IDR->GET_ITEM_GROUP_KEYS( ).
The table LT_ITEM_GROUP_KEYS now contains all the keys of the available label/value pairs that exist in the IDR area.
What you can do next is to use the following API methods to see which key is related to which label/value pair:
DATA: LT_ITEM_GROUP_KEYS TYPE T_ITEM_GROUP_KEYS.
LT_ITEM_GROUP_KEYS = LO_IDR->GET_ITEM_GROUP( … ).
You can make changes to them as follows:
LO_IDR->CHANGE_ITEM_GROUP_BY_VAL( ) or
LO_IDR->CHANGE_NAVIGATION_ITEM( ) or
LO_IDR->CHANGE_IMAGE_ITEM( ).
Which method you use depends on the type of the label/value pair (texts, navigation links or icons).
If a label/value pair has been created as a value reference to a Web Dynpro context element attribute, changing the context element automatically updates the value (that is, there is no need to use the IDR API for this).
