Alternative indicator: Not all technical spaces have been converted error

Hello Guys,

Alternative indicator: Not all technical spaces have been converted Message no. IL518

This error pops up as soon as the alternate labellng indicator testing. For every report, I got this error message and try to run the report RI_IFLOT2IFLOS as mentioned to fix this but no luck.

When I try to run this report, it says "Alternative labels for functional locations are not active" and it cannot be processed.

This is beacuse it was activated first for testing and again deactivated back again. But still system shows the same error.

How do I fix this ?
