Not possible to carry out the forecast - no historical data

Hi all,

in APO release 4.1, we face the following problem.

In a process chain for DP background processing a material with historical data can not be forecasted and the log states the following error message: "Not possible to carry out the forecast - no historical data" ("Message no. /SAPAPO/MA502")

Does anyone know why we get these error message?

Thanks in advance

Tobias
