CKMLCP error

Hi,

We have created new plant and extended the material to it in the month of feb 2013. production start up CKMSTART for this plant was done in march 2013. Now while running ckmlcp or ckmh we are getting abap runtime error only for this plant whereas costing run for all the other materials sucessfully completed. pls advice as this is very critical issue due to year end closing.

regards,

varsha
