Get the values that an user write in textbox with typed_context

Thanks for your time

I want to verificate, the values (product configuration) that an user have introduced,

I have written this code to get the values and verificate this.

  DATA:
      lr_info   TYPE REF TO cl_crm_bol_entity.

  lr_info ?= ME->typed_context->ISUORDERITEM->collection_wrapper->get_current( ).

lr_info has an atritbute T_EXTENSION_FIELDS, this is a table with the values of the product configuration, but I don't know how I can access to this values.

Could you help me, please??

Or other option to get the values to verificate this ??

Thanks
