ECC6 - ALV Grid Output Conversion Exit

Hi,

I'm creating a program in ECC6 to display the report in ALV grid by called FM: REUSE_ALV_GRID_DISPLAY.

EG: Select field (TPLNR) from table IFLOT. Value retrieved are: ?0100000000000000029. However, the output doesnt do the conversion exit to change the TPLNR value to format MY.FO.001.

I did the same in 4.6C system, the ALV report able to display the correct value of TPLNR. Eg: MY.FO.001 instead of

?0100000000000000029.

If anyone encountered the same issues in ECC6 system which In an ALV grid, it doesnt to display data that is based on a domain with a conversion exit?
