• What is the cause and solution for SAP error message MMPUR_SUBCONTRG_MSG000 - Assembly flow not available. Purchasing document not generated by MRP. ?

  The SAP error message MMPUR_SUBCONTRG_MSG000: Assembly flow not available. Purchasing document not generated by MRP typically occurs in the context of subcontracting scenarios within the Materials Management (MM) module. This error indicates that the system is unable to generate a purchasing document (like a purchase order) for a subcontracting process because the necessary assembly flow is not available.
  Causes:
  
  Missing Assembly Flow: The assembly flow for the component or material is not defined in the system. This could mean that the routing or bill of materials (BOM) is not set up correctly for the subcontracting process.
  MRP Settings: The Material Requirements Planning (MRP) settings may not be configured to generate purchase requisitions for subcontracting materials.
  Material Master Data: The material master data for the component may not be set up correctly, particularly in the purchasing or MRP views.
  Subcontracting Info Record: There may be no valid subcontracting info record for the material and vendor combination.
  MRP Type: The MRP type assigned to the material may not be appropriate for generating purchase requisitions.
  
  Solutions:
  
  Check Assembly Flow: Ensure that the assembly flow is correctly defined in the routing and that the BOM is properly set up for the subcontracting process.
  Review MRP Settings: Verify the MRP settings for the material. Ensure that the MRP type is set to a type that allows for the generation of purchase requisitions (e.g., MRP type 'PD' for planning).
  Material Master Data: Review the material master data for the component. Ensure that the purchasing and MRP views are correctly maintained.
  Subcontracting Info Record: Check if there is a valid subcontracting info record for the material and vendor. If not, create or update the info record.
  MRP Run: If changes have been made, run the MRP again to see if the purchasing document can now be generated.
