# MMPV Date Check Error in SAP: Causes and Fix > Source: https://netray.co/erp-help/sap-mmpv-date-check-error-fix > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer MMPV, the MM period-closing transaction, moves the current material posting period in table MARV to the next period. A date check error means the period you are trying to close does not follow the current MARV period, a prior period was skipped, or documents and locks prevent the move. Run the check-only mode first, read the log, and compare the MARV values with the company code's intended period. ## Kind error ## System sap ## Erp SAP ECC / S/4HANA ## Module MM Period Closing / MMPV ## Query mmpv_date_check error in sap ## Alternate Queries - MMPV date check error - sap mmpv period close error - sap close periods materials management MMPV - MARV current period wrong ## Applies To SAP ECC 6.0 and S/4HANA on-premise MM; exact message wording varies by release ## Steps ### How to resolve an MMPV date or period check error **Items:** - Run MMPV for the company code with 'Check only' (no update) first, so you see the messages without changing anything. - Read the current period in MARV via SE16N: fields LFGJA and LFMON are the current period, and VMGJA/VMMON the previous one. - Compare to the period you are closing. MMPV can only move forward one period at a time, and the target must follow the current period. - If periods have been skipped, run MMPV repeatedly for each month rather than jumping, or use MMRV to check allowed posting periods. - Resolve the objects named in the log: other users running MMPV, a held lock (SM12) on the company code, or documents in the period that block closing. - If MARV is genuinely wrong, correct it using the period-correction function (OMSY) under your controller's approval. - Run MMPV again in update mode, then verify MARV and test a posting in the new period with MIGO. ## Sections ### What MMPV actually changes **Body:** MMPV does not post documents. It updates the period control record in MARV so goods movements are posted to the new period and the previous period becomes the allowed prior period. Together with MMRV (allowed posting periods) and OB52 (FI periods), it defines where users can post. That is why the error often points to a mismatch between the three: MM period (MARV), FI period (OB52) and the document date the user used. In S/4HANA the same logic applies, and with the Universal Journal your finance team still opens and closes FI periods separately. Coordinate the order of the steps. ### Typical causes **Body:** Skipped periods. If the last closing was months ago, MARV is far behind and a jump to the current month is refused. Close step by step. Wrong target. The user entered a period that does not directly follow the current one, or a fiscal year change is involved and the next year's variant is not set up. Blocking conditions. Open inventory counts, locked company codes or parallel processing can block the move; MMPV also checks that certain closing steps for the previous period, such as valuation runs, are complete in your process. Testing in the wrong client or company code. Check that you are working on the right plant's company code, as MARV is kept per company code. ### Safe correction **Body:** Treat MARV as a control table. Changing it directly is risky, and in most companies it needs finance sign-off. Prefer MMPV and OMSY over table edits, and document why the period was wrong. Look at the posting pattern before you change anything, because users posting into a wrong period can create a lot of corrections later. **Code:** - -- Read-only check in SE16N - Table: MARV - Fields: BUKRS, LFGJA, LFMON, VMGJA, VMMON, XRUFB ## Pitfalls - Jumping several months in one run instead of closing each period in sequence. - Closing the MM period before finance has finished valuation and reconciliation for the previous one. - Editing MARV directly in production without approval. - Forgetting to open MMRV allowed periods for the new year. ## Ai Angle Period close questions are mostly about reading state across MARV, MMRV and FI. Netray's ERPray can run this kind of lookup in plain language against your own SAP system, read-only by default, showing the query it ran and respecting SAP authorizations, with the model served on your own hardware when the system is on-prem. It explains and finds the data; it does not replace configuration decisions or post documents without human approval. ## Faq ### What does MMPV do in SAP? **Answer:** MMPV closes the current material posting period for a company code and opens the next one by updating the period control record in MARV. It does not post accounting documents. ### Can I close an MM period that is not the next one? **Answer:** No. MMPV moves forward one period at a time. If several periods were not closed, run MMPV for each in sequence. ### What is the difference between MMPV and MMRV? **Answer:** MMPV changes the current period for MM; MMRV sets the allowed posting periods, including the previous and next period, so users can post in them. ### Who should run MMPV? **Answer:** Usually someone from finance or materials accounting, in coordination with inventory control, because it affects where all goods movements post for the whole company code. ## Search terms mmpv date check error, sap mmpv, sap close periods materials management, MARV current period, MMRV allowed posting periods, sap mm period close, OMSY period correction, mmpv error sap --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
