Fields of Authorization Object 'I_TCODE'

Hi group.

We are implementing Enterprise Search. In the connector structure BUS_2038 have the Fields of Authorization Object 'I_TCODE' field with the following values:

Authorization Field Name     Value

TCD                                        IQS3;IQS23;IW23;IW29;QM03

My question is, is there any way to eliminate one of these values? It is resulting as follows:

Authorization Field Name     Value

TCD                                        IW23

We need is to leave only the transaction IW23.

Thank you very much.

Mariano.
