Posting only possible in periods 2009/04 and 2009/03 in company code BP01
Message no. M7053
The posting date entered is not within one of the permitted posting periods (current period/previous period).
This can be due to one of two reasons:
The correct current period has not been set in the system.
For the system, the first of the entered periods is the current period. At the beginning of a new period, your systems administrator must change the current period in the material master record, using the function "Shift periods". This has not yet been done.
You have entered a wrong date in the field "Posting date".
Check the posting date and correct it if necessary. If your input is correct, inform your systems administrator that the "period shifting" (period-end closing) process has not yet been completed. Copied from M8022
