Error determining Planning Periods for Calendar

[Former Member]

Hi Team,

     When performing MRP Run, I get the message "Error determining Planning Periods for Calendar" for a Plant. I checked the Planning Calendar for this Plant using MD27 and also the Valid To is until 2020 which is also fine.

Is there any other place where the Planning Periods need to be checked? Kindly help me regarding this.

Thanks in advance for the help and for your time.

Thanks & Regards,

Srikanth.

Hello,

Error message 61123 'Error determining planning periods calendar

It could be due to planning calendar is insufficiently maintained. There are MRP items (requirements, planned orders, production orders, purchase orders, and so on, ... ) with a requirements date or an input date before or after the period that is defined in the planning calendar.

Check the requirements dates and delivery dates of the MRP items of the material in question with the current stock/requirements list in transaction MD04. Enhance the calendar with transaction MD26 'Change Planning Calendar' so that these dates will be considered.
