Posting period ### / #### is not open

What it actually means

The period your posting date falls into is closed, so SAP refuses the document.

Why it happens

How to fix it

  1. 1Check the open periods in OB52 for the FI posting period variant (per account type: +, A, D, K, S).
  2. 2For material movements, check and roll the MM period with MMPV (it moves the current period forward one month).
  3. 3If your date is simply wrong, correct the posting date to a date inside an open period.
  4. 4If the period genuinely must be reopened, ask the finance owner — this is a controlled activity, not a self-service fix.

Stopping it happening again

Agree the close calendar with finance, and validate posting dates in any data load before running it.
