MARC-VINT1 not updated using RMDATIND

I'm loading Material Master Data using LSMW. This LSMW uses standard program RMDATIND.

After post load validation, I noticed that MARC-VINT1 was not updated though a value was passed on.

I checked the field mapping for that field to check if maybe it was not mapped at all, but it is mapped.

I wonder maybe if it's in the load program.

Any thoughts about this?

Thank you.
