• What is the cause and solution for SAP error message FRMLDLG191 - Input material &1 is output mat. of a formula for which no BOM exists ?

  The SAP error message FRMLDLG191 indicates that there is an issue with a formula in the system where the input material specified is also being used as an output material in a formula, but there is no Bill of Materials (BOM) defined for that output material. This can occur in the context of production planning and recipe management, particularly in industries like manufacturing and process industries.
  Cause:
  
  Missing BOM: The primary cause of this error is that the output material (which is also being used as an input) does not have a corresponding BOM defined in the system. A BOM is necessary to define the components required to produce a finished product.
  Incorrect Configuration: There may be a configuration issue where the formula is incorrectly set up, leading to the system not recognizing the relationship between the input and output materials.
  Data Inconsistency: There could be inconsistencies in the master data, such as the material master records not being properly maintained.
  
  Solution:
  
  Create a BOM: The most straightforward solution is to create a BOM for the output material. This can be done through the transaction code CS01 (Create BOM) in SAP. Ensure that all necessary components are included in the BOM.
  Check Formula Configuration: Review the formula configuration to ensure that the input and output materials are correctly defined. You can use transaction code C201 (Create Recipe) or C202 (Change Recipe) to check the details.
  Material Master Maintenance: Verify that the material master records for both the input and output materials are correctly maintained. Ensure that the necessary views (like Basic Data, MRP, and Work Scheduling) are filled out correctly.
  Consult Documentation: If you are unsure about the setup, refer to SAP documentation or consult with a functional consultant who specializes in production planning or recipe management.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), C201 (Create Recipe), and C202 (Change Recipe).
  Master Data Management: Ensure that your material master data is up to date and accurately reflects the relationships between materials.
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address known issues.
  User Authorization: Ensure that you have the necessary authorizations to create or modify BOMs and recipes in the system.
  
  By addressing the missing BOM and ensuring proper configuration, you should be able to resolve the FRMLDLG191 error in SAP.
