I often use Rebrickable to check inventories as they have a nice 'view'
where parts are shown large and easy to identify. I have not found a similar
view in Bricklink.
Lately however, I noticed there are discrepancies between the two systems. I
was under the impression these were from the same source, but apparently not.
Anyone has info on this issue?

Thank You

What sort of discrepancies? Part variations? Missing parts? Modern or vintage
sets?

They are not from the same source.

Inventories on Rebrickable are taken directly from LEGO, which means they contain
the inventory as reported by LEGO, which may not be the same as was actually
shipped out and which does not cater for all variants that Bricklink distinguishes
(but may distinguish variants that are considered as the same on Bricklink).

Inventories on Bricklink are (nowadays) pre-filled from the same source of LEGO,
but are always manually checked and verified against what was actually packed.
The Bricklink inventories are also amended by distinguishing variants, counting
the extras (like most small parts), alternates (like different variants) and
counterparts (like stickers applied on parts, or wheel-tire assemblies).

Also, please keep in mind that although LEGO's part numbers (design ids)
are used on multiple platforms, the numbering of variants and decorated parts
may differ from platform to platform.

Well, here is one example. For set 7649 Mars Mission, Part 61485 shows up in

WHITE on Rebrickable, and in BLACK on BrickLink

I've seen cases where the part is missing completely from Rebrickable.

Also, Rebrickable now shows the extra parts (which Lego catalogs never do).

Well, this is a turntable base:
 
Part No: 61485  Name: Turntable 4 x 4 Square Base, Locking
* 
61485 Turntable 4 x 4 Square Base, Locking
Parts: Turntable {Black}
It is used with a top:
 
Part No: 60474  Name: Plate, Round 4 x 4 with Hole
* 
60474 Plate, Round 4 x 4 with Hole
Parts: Plate, Round {White}
Could it be that Rebrickable shows white on the assembly of the two? Like:
 
Part No: 60474c01  Name: Turntable 4 x 4 x 2/3 with Black Square Base, Free-Spinning (60474 / 61485)
* 
60474c01 (Inv) Turntable 4 x 4 x 2/3 with Black Square Base, Free-Spinning (60474 / 61485)
Parts: Turntable {White}
(which is in the "alternate items" on the inventory for your set).

Niek.

“Counterpart,” not “Alternate”

Rebrickable (wrongly) has the base in White (and I don’t think they do assemblies/counterparts
there).
Brickset (which has this inventory from LEGO) has it in Black, like BL.

I think this is just that OP stumbled upon an inventory with errors on Rebrickable. 
They have a forum there too where I guess this can be discussed.
