• What is the cause and solution for SAP error message W0159 - Do not set the indicator "Do not prepare material" ?

  Certainly! Here's a detailed explanation regarding the SAP error message W0159: "Do not set the indicator 'Do not prepare material'":
  
  SAP Message W0159: "Do not set the indicator 'Do not prepare material'"
  
  1. Cause
  This warning message appears when you try to set the indicator "Do not prepare material" (in German: Material nicht vorbereiten) in a process or transaction where this setting is not allowed or does not make sense.
  
  The indicator "Do not prepare material" is typically used in production or procurement processes to specify that the material should not be prepared or staged for production.
  However, in certain contexts (e.g., specific production orders, process orders, or material types), this indicator must not be set because the system requires the material to be prepared for the process to proceed correctly.
  Setting this indicator incorrectly can lead to inconsistencies in material staging, production planning, or goods movements.
  
  
  2. When does this occur?
  
  When creating or changing production/process orders.
  When setting parameters in material staging or production scheduling.
  When the system logic or configuration forbids the use of this indicator for the material or order type.
  Possibly during MRP runs or order confirmations if the indicator conflicts with system requirements.
  
  
  3. Solution
  
  Do not set the indicator "Do not prepare material" if the system issues this warning.
  Review the business process and confirm whether the material should indeed be prepared/staged.
  If the indicator was set by mistake, remove it.
  If you believe the indicator should be allowed, check the configuration or master data settings:
  
  Verify the material master settings (e.g., MRP type, procurement type).
  Check the order type configuration and whether it allows this indicator.
  Review user exits or custom enhancements that might enforce this restriction.
  
  
  Consult with your SAP PP (Production Planning) or MM (Materials Management) consultant to understand the process requirements.
  If necessary, adjust the process or configuration to align with business needs.
