Hi Frank,
sorry for the late reply. Yes, acutally there is an update. Seems that there is an issue in the interplay of the ALV and the CONTAINS function in your HDB revision.
I guess asking you to upgrade your HANA is not an option, therefore, I propose to use another workaround.
I previously proposed to use a CAST on a dedicated data element MY_LIFNR (which does not feature an ALPHA CONVERSION). Can you alternatively use such a data element in combination with the method field_catalog()->set_data_element( ... ) function of your IDA ALV before calling the enable_text_search( ... ) function?
Works for me, but I don't have a system with exaclty the same versions (ABAP and HANA) you have in your system.
Best,
Jasmin
