BOL - change Text

Hi

I am trying to change the text for a business transaction on the web ic.

I create a business transaction and initialise a text with a value.

When I save the transaction in the follow up screen I am trying to update this text with a new value, but the value does not change. This only happens with the text entities. I change other entities successfully.

Does anyone know why texts would be locked. Could this be config.

here is the code I use.. Any help would be great.

************************************************

lv_text_h = lv_order_h->get_related_entity ( 'BTHeaderTextSet').

lv_texts = lv_text_h->get_related_entities(

IV_RELATION_NAME = 'BTTextHAll'

iv_mode = '' ).

result = lv_texts->get_first( ).

while result is bound.

textID = result->get_property_as_string( 'TDID' ).

if textID = 'Z030'.

result->set_property( iv_attr_name = 'CONC_LINES'

iv_value = text ).

exit.

endif.

result = lv_texts->get_next( ).

endwhile.

if lr_transaction->save( ) eq abap_true.

lr_transaction->commit( ).

else.

lr_transaction->rollback( ).

IF me->view_manager IS BOUND.

lr_msg_service = view_manager->get_message_service( ).

CALL METHOD lr_msg_service->add_message

iv_msg_type = if_genil_message_container=>mt_error

iv_msg_id = 'CRM_IC_IARECORD'

iv_msg_number = '016'

iv_important_info = abap_true.

ENDIF.

endif.
