User Defined Function in SAP HCI


We are using SAP HCI to for integrating on-premise SAP ECC and on-cloud SAP C4C systems. There is a requirement to map source field TDLINE to a target field CustomerText. TDLINE has 0...unbounded cardinality where as target field has 0...1 cardinality. Now, we need to concatenate all the values of TDLINE queue and map it to the target CustomerText field.

This requirement is straightforward in PI by creating a UDF. However, in HCI there is no provision to create a UDF in mapping. Is there a way we create some kind of custom function to achieve the mapping functionality we need?
