"Error determining planning periods for calendar " when running a program

[former_member184595]

Hi,

When i am running a program with date range say "01/05/2011" to "30/06/2011",the program is executing successfully without any error. When i am executing the same program with date range as a) "01/05/2009" to "30/06/2011" and b)"01/05/2008" to "30/06/2011" the program is failing with error as "Error determining planning periods for calendar". Can anyone suggest me what i should do to avoid the failure of the program with above date ranges also.

Thanks in advance,

Dear,

Error message 61123:"Error determining planning periods for calendar &".The PPC planning calendar specified in the material master MRP 2 view for the material is incorrectly.

The planning calendar periods are insufficiently maintained for the planning calendar used.

Check the period of planning calendar in MD26 and generate the correct period.You can avoid the problem in several ways:

Maintain the planning calendar far enough in the future (at least until beyond the end of the planning horizon).

Also check any demand is lies beyond the validity period of planning calendar.

Reduction of the planning horizon of MRP also can control such issue, as MRP planning horizon lies in an area in which the planning calendar is no longer maintained

Dear,

For which material and PPC calendar are you getting the error?

For that material check in MD04 last MRP element and its date.

Suppose demand is there on May 2012 and check the PPC calendar which is assign to material.

If the PPC calendar is having the validity as March 2012 then system issue this message.

There are few OSS note there to debug this issue Please check.
