How To Fix MRTRS030 - No connection exists between the formulas of the selected stages

SAP Error Message - Details

• Message type: E = Error

• Message class: MRTRS - RMS-MRTRS : Error Messages for Master Recipe Transformation

• Message number: 030

• Message text: No connection exists between the formulas of the selected stages

What causes this issue?

You have selected recipe stages that are not directly linked via the
formulas. Since this has produced gaps, the system cannot determine a
BOM for the selected formulas.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Choose stages that are linked via the formulas. To do so, also select
the formulas that are not already chosen but are included in the
selected stages OR delete the formulas that are included in the stages
that are not selected.

• What is the cause and solution for SAP error message MRTRS030 - No connection exists between the formulas of the selected stages ?

  The SAP error message MRTRS030, which states "No connection exists between the formulas of the selected stages," typically occurs in the context of the SAP Material Requirements Planning (MRP) or Production Planning (PP) modules. This error indicates that there is a problem with the configuration of the routing or the production process, specifically regarding the connections between different stages or operations in a production order or routing.
  Cause:
  
  Missing Connections: The error usually arises when there are no defined connections between the formulas or operations in the routing. This can happen if the routing is incomplete or incorrectly set up.
  Incorrect Formula Assignment: If the formulas assigned to different stages do not have the necessary links or dependencies, the system cannot process them correctly.
  Routing Configuration Issues: There may be issues with how the routing is configured in the system, such as missing or incorrect sequence numbers or operation assignments.
  Data Inconsistencies: Inconsistencies in the master data, such as material master records or bill of materials (BOM), can also lead to this error.
  
  Solution:
  
  Check Routing Configuration: Review the routing for the material in question. Ensure that all operations are correctly defined and that there are connections between the stages. You can do this by navigating to the routing in the SAP system and checking the sequence of operations.
  Define Connections: If there are missing connections, you may need to define them. This can involve linking the output of one operation to the input of another or ensuring that the correct formulas are assigned to each operation.
  Review Formula Assignments: Ensure that the formulas assigned to each stage are correct and that they are properly linked. You may need to adjust the formula assignments in the routing.
  Check Master Data: Verify that the master data (material master, BOM, etc.) is correctly set up and that there are no inconsistencies that could be causing the issue.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on routing and formula connections, as the exact steps may vary based on your SAP version and configuration.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CA01 (Create Routing), CA02 (Change Routing), or CA03 (Display Routing) to access and modify routing information.
