SNP Interactive Planning. Problems for SNP PPM plant

Hi All

Can you advise please why SNP interactive planning does not create SNP planned order when there are SNP and PP/DS related PPMs together.

And once i delete SNP PPM, SNP interactive planning creates SNP Planned Order without any problems.

Once i again create SNP PPM and run SNP interactive planning- it does not create planned order to fullfill demand.

Thanks

Best Regards

Andrey
