CODEDS = Continuous Deductions thus yes your PMQ (coudl also be SQ's for anyone else)
The information you provide above is repeat of the "F6" screen within CCPS and as such does provide a good visual. According to the info you provided above yes your pays should be 1995.81/2. You state you only received $765.00 per pay so that does create a question.
On your printout, look at the top right side and see which month the screen capture was for. Reason I mention this is that by default the F6 screen shows the amounts for the upcoming month, and not the current month. For that you have to scroll up to see the current month. If indeed it is for the following month, then perhaps there is an upcoming adjustment which will see you getting more money. IE a pay incentive, change in taxes etc etc On the other hand, if the printout is in fact for May, and that you pay for Mid May was 765.00, then perhaps an ongoing adjustment affected that pay. IE start of PMQ, reduction in PLD, change in taxes etc.
The screen you need to look at is the FZQEDE which displays all the activity ongoing on your pay, sort of like a bank account showing all the transactions. The F6 only shows predictable entitlements, but does not reflect and adjustments occuring part way through that month or even retroactively.
The short of it is that 1995.81 is your NME (Net Monthly Entitlement) and should be divided in 2 for your 2 pays, but you must confirm for which month. If it is for the current month, it may not reflect any adjustments that occured during that month. As I cannot access your account in CCPS and investigate it myself, that is all the information that can be provided to you.
Hope this helps.
