Dear Friends,

But in Schedule lines when I try to enter plan for two different Prod. Version on same date, it is deleting one and creating Demand for only one version in a day. and giving the Message 6P336.

But in different date for different version, it is accepting. what setting I need to do to? to meet my following requirement?

Same material is produced in the same day with two differnt versions and demand should be entered in MD61 for two different versions.

I hope u guys will help in this.
