• What is the cause and solution for SAP error message /SAPAPO/RRP704 - Only start date is known; forward scheduling is not possible ?

  The SAP error message /SAPAPO/RRP704 Only start date is known; forward scheduling is not possible typically occurs in the context of Advanced Planning and Optimization (APO) when the system is unable to perform forward scheduling due to insufficient information about the production process or the planning parameters.
  Cause:
  
  Missing End Date: The system requires both a start date and an end date to perform forward scheduling. If only the start date is provided, the system cannot determine the duration of the process.
  Incomplete Master Data: The master data for the product or resource may be incomplete, lacking necessary information such as lead times, production times, or capacity.
  Planning Parameters: The planning parameters for the product or resource may not be set correctly, leading to the inability to calculate the scheduling.
  Resource Availability: If the resources required for production are not available or not defined properly, the system cannot schedule the production forward.
  
  Solution:
  
  Check and Update Master Data: Ensure that all relevant master data (e.g., material master, resource master) is complete and accurate. This includes lead times, production times, and any other relevant parameters.
  Define End Date: If possible, provide an end date for the scheduling. This can sometimes be done by adjusting the planning parameters or the production process.
  Review Planning Parameters: Check the planning parameters for the product and resource in the APO system. Ensure that they are set correctly to allow for forward scheduling.
  Resource Availability: Verify that the resources required for production are available and properly defined in the system. This includes checking for any maintenance or downtime that may affect scheduling.
  Use Backward Scheduling: If forward scheduling is not possible, consider using backward scheduling if it fits the planning scenario.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/RRP3 (Product View) or /SAPAPO/RRP4 (Resource View) to analyze the planning situation.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  Documentation: Refer to SAP documentation on APO and scheduling to understand the requirements for forward scheduling and how to configure the system properly.
  
  By addressing the underlying causes and ensuring that all necessary data is available, you should be able to resolve the error and enable forward scheduling in your SAP APO environment.
