When selecting a service provider for the implementation of SAP PP in production planning, there are several important steps to consider:

1. Requirements specification: First, clarify your specific requirements for production planning and ensure that you have a clear idea of what you expect from SAP PP.
2. Market research: Conduct a thorough market study to identify potential providers with experience in SAP PP implementation. Consider factors such as reputation, references, and industry experience.
3. Provider selection: Based on your market research, create a shortlist of providers that meet your requirements. Get in touch with them and request further information about their experiences, methodologies, and reference projects.
4. Evaluation: Evaluate the providers based on criteria such as experience, expertise, team composition, project management approach, and costs. Ensure that the provider has qualified personnel familiar with SAP PP.
5. Reference check: Request references from the providers and reach out to them to gather feedback on their collaboration and achieved results. This can help you better assess the reliability and quality of the providers.
6. Contract negotiations: Once you have chosen a provider, negotiate the contract terms. Ensure that all essential aspects, such as scope of work, timeline, costs, and post-implementation support, are clearly defined.
7. Project management: During the implementation, close collaboration and regular communication with the provider are crucial. Ensure that clear project management structures are established and regular progress reports are obtained.

Through thorough preparation, careful evaluation, and selection, you can find the appropriate provider for implementing SAP PP in your production planning and ensure a successful collaboration.
