Error determining planning periods for calendar

[Former Member]

Hello SAP Guru's

We are receiving the above error when trying to go into MD04 for a particular material. we have checked the forecast agains the planning calendar and the dates in the forecast and demand planning are approximately 2 years less than the end date in the planning calendar.

Checking SAP it has said to extend the planing calendar past the planning horizon. It is already extended past the planning horizon.

The only issue with this product is that the material will soon be superseded by another material, this has a different calendar assigned to it. Could this be the problem?

Any info gratefully received.

Thanks

I found that this problem was caused by a someone entering an incorrect date that was outside the planning period. They did not want to update the planning calendars as this would have been too time consuming but the only way around this would be to change the planning date directly in the MD04 table which is not something that we would usually recommend. Planning calendars were changed.

Generally such errors come while creating a forecast or SOP for particular products / plants combination & not at MD04 level

Can you give the exact description of the error along with error message number

Also check the factory calendor for that plant + check the planning horizon of the plant / MRP Group

Hello Vicky,

The error occurs when first going into MD04. The exact error message is as follows:

Error determining planning periods for calendar M14

Message no. 61123

Diagnosis

The system could not determine sufficient planning periods by the planning calendar to group requirements by planning calendar periods for all the requirements planned in the future.

System Response

When a material is planned by using the periodical lot size by planning calendar, sufficient periods must be calculated to group requirements by the planning calendar for all requirements.

Procedure

Rework the planning calendar with which the material was planned, which means calculate new planning calendar periods.

To do this, go to Customizing for MRP, under the activity Change PPC periods.

Hi Watson

This is b'cos M14 is the planning calendor which u have maintained whose validity is not matching with your requirements

Check the planning calendor in MD26 / 27.......This could be the only reason. i.e. Maintain the planning calendar far enough in the future (at least until beyond the end of the planning horizon)

Also u can refer to SAP Note # 368079

This will surely help u

Check and revert

Thanks Vicky. I have already checked these things but still have the problem. The planning calendar is past the end date of the planning horizon.

Thanks for you help.
