Movement Type Posting in GTS

Hello All,

I have an issue and user is reporting.

A user has created a PO with the Movement Type of 102 (reversal), but when you look at the stock overview in GTS for that material/stock ID it shows the Rcpt/Issue at a + (plus sign) instead of a - (negative sign). 

Is this something that needs to be corrected in GTS so the values read correctly?

Thank you in advance.
