• What is the cause and solution for SAP error message FRMLMSC223 - Material &1 is part of a multilevel loop ?

  The SAP error message FRMLMSC223 indicates that there is a multilevel loop involving the specified material in the context of a bill of materials (BOM) or a production process. This typically occurs when there are circular references in the BOM or routing, which can lead to infinite loops during calculations or processing.
  
  Cause:
  
  Circular References: The most common cause of this error is that the material is part of a circular reference in the BOM. For example, if Material A is a component of Material B, and Material B is also a component of Material A, this creates a loop.
  Incorrect BOM Structure: The BOM may have been incorrectly structured, leading to unintended dependencies between materials.
  Routing Issues: Similar issues can arise in routing where operations reference each other in a circular manner.
  
  
  Solution:
  
  
  Review BOM Structure: Check the BOM for the material in question. Look for any circular references and correct them. You can do
