Unit Test run error

[ChristianFinkbeiner]

We receive unit Test errors from the ABAP UNIT RUNNER.

One of them is an exception from the xco lib

LTC_RAP_NODE GET_FIELDS_FROM_ABSTRACTENTITY Exception Error <CX_XCO_NEWS_EXCEPTION>

Message is:
Data element TRKORR does not exist for the provided read state and origin.
Test 'LTC_RAP_NODE->GET_FIELDS_FROM_ABSTRACTENTITY' in Main Program 'ZDMO_CL_RAP_NODE==============CP'

View in Question is
gc_abstract_entity_name TYPE string VALUE 'D_SELECTCUSTOMIZINGTRANSPTREQP ',

It seems that the data type TRKORR is not accessible through the library - maybe because feature toggle A4C_OLD_REPOSITORY_APIS has not status released

Kind regards,
