Mapping XML-element with transformer in SAP Business Connector

Hi,

I receive a XML file with SAP Business Connector and I am trying to map the element "PARTNER_ID" of segment "E1ADRM1" (type: QALITY02) with the help of a transformer. The service of the transformer is "lookupTable".

I setup the mapping in this table (2 colums: received value / my value) and it works fine for the control segment "EDI_DC40" for the element "SNDPRN".

But it doesn't work for "PARTNER_ID" in "E1ADRM1". I may say, that I am receiving the segment "E1ADRM1" 2 times in this XML file. Is this the problem?
