Check your update settings:

• Check the update setting of the info structure in transaction MC25.
• For standard info structure S140, you can use the standard formulas 141 – 144.
• Formula 140 is the standard formula, independent from the info structure, and must always be entered for characteristic Product allocation object.
• If you use your self-defined info structure, you can use formulas 141 - 144 as a copy reference and you must adjust them to your info structure.
• The key figure incoming orders quantity (AEMENGE) must be updated. Update must occur on schedule line level (quantity and date are transferred from schedule line, MCVBEP). The formulas of the characteristics are processed on schedule line level. The update date is the delivery date (EDATU).

Check whether statistics groups for Material, Customer, Sales Document Type and Sales Document Item Category are correctly maintained.

Check whether Assign Update Group at Item Level and Assign Update Group at Header Level are correctly maintained.

 Check whether the updating of the info structure is set to synchronous (transaction OMO1). For product allocation synchronous updating is necessary.

You can check the update for each document in transaction MCVR.

Here is displayed which info structures are updated using which update groups.

Check the validity of the product allocation object and the factory calendar:

Check the validity of the relevant product allocation object in transaction OV4Z (V_T190-KTGBI).  Make sure that the date maintained here is inside the validity of your factory calendar.

Check the validity of the factory calendar of the shipping point and the factory calendar of the route. Make sure that the validity of both calendars is maintained at least 2-3 years into the future.
