SAP Note 14040 - Error during planning period calculation

Symptom:

Program: SAPMM61X
Error ID: 123
The materials planning in transaction MD01, MD02 or MD03 terminates with error message 61123 'Error determining planning periods calendar &'.

Cause and prerequisites

This may be due to several reasons:

1. The 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.

2. Program error in Releases 3.0F and 3.1G. The program error only occurs if you are working with planned finish = period end in the lot-sizing procedure.

Solution

1. 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.

2. Implement correction P30K141474.
